Students identify biotic and abiotic components of ecosystems and analyze the cycling of matter that takes place within them. This includes an investigation of the transfer of energy that occurs at various consumer levels, the implications of the loss of produers and consumers to the transfer of energy, and the potential for bioaccumulation within an ecosystem. Students explore ecological succession and assess the positive and negative impacts of human interventions on this natural process. Students discuss environment, social and economic factors that should be considered in the management and preservation of ecosystems. They propose a course of action that would help protect the habitat of a particular organism. Students observe microorganisms with microscopes and discuss their beneficial and harmful roles. Students consider how knowledge of microorganisms has imprved food production and preservation techniques.From the Grade 5-8 Science Foundations for ImplementationThe Importance of Understanding Interactions within Ecosystems: Humans are an animal species, a biotic part of virtually every ecosystem around the world and it is vitally important for young people to understand what previous generations have often tried to ignore. Human populations and human needs have escalated dramatically over the last century, from a population of around 2 billion in 1920 to 7.5 billion less than a century later. About a quarter of all modern humans that have ever existed are living today, and our impact on the natural world is colossal, occasionally positive, all too often sharply negative. In order to understand our impact on ecosystems, however, students must know what an ecosystem is and the components of the ecosystem and the diverse interactions between the biotic (living) and abiotic (non-living) elements of an ecosystem. They must understand the cycling of matter and energy, and of the importance of every organism within the ecosystem, including often unloved scavengers and decomposers, such as vultures and bacteria. They should understand notions like bioaccumulation and ecological succession, that ecosystems are finely balanced and easily disrupted, and that they are not powerless to help ecosystems. The purpose of the unit is not to deride modern society for its industrial or technological advances- to put it bluntly, there are too many of us on Earth to give it up wholesale and in any case, in Western societies at least, few can deny that more of us have lived better than ever before. However, we must be considerate of the other organisms that share our planet with us. We have to understand that there is only one Earth and that ecosystems, and on a wider scale, the whole biosphere, are like living beings. If we totally disregard the needs of our planet, we might find that biosphere will collapse, and us with it. We cannot live without the Earth, it is our duty to learn as much as we can about it and do our best to protect its living and non-living systems. Unit Activities: My goal for this unit is to challenge the traditional paradigm of Middle Years Science education, wherein fun activities supplement traditional methods of educations, such as lecturing and testing. As much as possible, students will be actively engaged in creative assignments and activities that will test not just their understanding, but their creativity. Some of these assignments will call upon students to reflect and create individually, others to work in groups and some in a whole-class environment. The major graded assignments for this unit will consist of the following: The creation of a functional animal shelter, which will be donated to an appropriate non-profit agency, such as Brandon Riverbank Inc. or Ducks Unlimited for their use. The animal shelters will be completed by table groups. The conduction of a research project on one harmful or helpful role that microorganisms play. These research projects will be done either in pairs or individually. The creation of a model of a functioning ecosystem, using animals of the students’ own creation. Other activities will include games such as the Energy Game and Who Wants To Be An Energy Expert, hands-on activities like a field trip to the Riverbank Discovery Centre and the use of microscopes, the examination of media such as the award-winning Planet Earth documentary and educational YouTube videos, written worksheets and reflections, and even a free snack with surprisingly educational results. Essential Questions:The list of fifteen outcomes presented in the Manitoba Science Curriculum is rather daunting, but can be organized easily enough into key questions, which students must understand in order to have successfully completed the unit. What is an Ecosystem? Students must know what an ecosystem is and all the parts that comprise it. How do living things function within an ecosystem? Students must know the roles of organisms in an ecosystem, from producers to apex predators. They must grasp the transfer of energy and matter, and concepts like ecological succession. How do human beings interact with an ecosystem? Students should have a grasp of the different ways that humans interact with their ecosystems, both positive and negative. They should have a sense of some ways in which they can encourage sustainability and responsible practices, on an individual and social level. Cross-Curriculum Connections: It is difficult to satisfy all of the competing needs of a successful middle school curriculum, and virtually impossible to do so if one adhered strictly to lesson plans that could only relate to a single subject. While most of the material in this unit is decidedly Science-oriented, there are significant connections to other subject areas present in the offered material. English Language Arts: There are significant links between the material in this unit and English Language Arts, for much of the material relies on skills of reading, writing and representing that are key to ELA. Research skills are a significant requirement of completing the unit successfully, another skill that is of great importance in English Language Arts. Social Studies: Material that has to do with development, sustainability and ecological protection have significant crossover with elements of Grade 7 social studies that deal with sustainable development and human impact on the environment. In many ways, the Science material that is presented here supplements the Social Studies material on World Communities. Physical Education/Health: Some of the activities involve direct physical activity, such as the field trip to the Riverbank Discovery Centre, and the Energy Game, which can only be played while up and walking around the classroom. The sections of the unit that deal with microorganisms are significant as well for a potential crossover into Health material, as microorganisms play a major role in food production but also in the cause of disease. Assessment:Unit Assessment Philosophy: The assessment of this unit and all other units that I teach is assessment not only of learning, but for learning and as learning as well. Assessment is not something that simply happens at the end of a unit, but occurs throughout it. It is not simply for the purpose of getting a grade- indeed, getting a grade is decidedly secondary to the goals of both assessing the learning that has taken place and facilitating further learning. Assessment Techniques: Observation: Observation is an everyday activity in the classroom, with incidental notes taken so that important observations or impressions can be recorded permanently. Not only will I go about and examine student work, but I will engage them periodically in conversation about their work and assess their understanding of the task at hand and the core knowledge and skills behind it there. Conferences: Students will frequently engage in conferences with each other in which they will look at each other’s work and give feedback on strengths and areas that need improvement. As well, I will occasionally speak with students, perhaps two or three times in the teaching of a cluster, perhaps about a specific thing that they are working on, but perhaps about the unit generally. It is there that I can not only get an impression of student learning, but it is also an opportunity for students to communicate openly and honestly about any questions or concerns they may have. Reflections: Students will be frequently called upon to write reflections upon both what they have learned in instruction and upon the work they have done. Self-assessment will be an important and ongoing process, giving the student a strong sense of their own strengths, weaknesses and learning, while simultaneously granting the teacher the same perspective. These reflections could be important in shaping instruction as the unit goes on- for example, if student reflections generally show that there is not an understanding of the concept of ecological succession, I may decide to include a quick review of the concept or possibly even another full lesson on it. I also believe that the making of honest and thorough self-assessments is a skill in and of itself, and students should be encouraged to do so often. A final self-assessment will be given at the end of the unit, which will provide students with an opportunity to reflect on the totality of their learning. This will also be paired with an instructor evaluation in which they assess the performance of the teacher delivering the unit instruction. Graded Work: The provincial government requires there to be graded work as a feature of Middle Years assessment. While this may not be ideal, there are a few principles that can be followed in order to make it more valuable and less arbitrary for students. The first of which is to base grades around a standard, wherein students whom meet the standard get good grades, as opposed to simply passing. Graded work that meets the standard for the assignment, as set out in the rubric will receive a grade of about 80 percent, leaving some room for those who exceed standards to receive higher grades and giving some leeway for students who are approaching or struggling with the standards.There will be four elements of this unit which will be formally graded projects, with 20% of the unit grade being reserved for the completion of minor assignments. Any student who completes all of the work in the term will receive the full 20% for this. Habitat Project: In this project, students will be creating a functional habitat for a particular species of animal. The most important element of success in this project is functionality- the animal should be able to actually live in the shelter designed, with creativity and a brief write-up about the shelter and how it satisfies the needs of the animal in question also being called for. This project is worth 25% of the total unit grade. Microorganism Research Project: In this project, one or a pair of students will do research on one harmful or helpful role that microorganisms play for us. The primary criteria for evaluation will be the quality of the content in the project, the depth of the research done and the organization and quality of writing inside the project. This project is worth 20% of the total unit grade. Ecosystem Project: In this project, students will be creating their own ecosystem and are expected to include all the functional levels of the ecosystem, including scavengers and decomposers. Originality and creativity will also be important factors in this project, which will be the most significant graded assessment piece in the unit, being worth 25% of the total unit grade. Vocabulary Quiz: Two vocabulary quizzes will be issued during the teaching of the unit, in order to assess the knowledge of key vocabulary amongst students. The quizzes are each worth 5%, for a total of 10%. Lesson #1: What Is An Ecosystem?Lesson PlanMr. KeenSubject: ScienceTopic: Introduction to EcosystemsUnit: Interactions within EcosystemsGrade: Grade 7Learning Outcomes: 7-1-01: Use appropriate vocabulary related to their investigations of interactions within ecosystems.7-1-02: Define ecosystem and describe various examples that range from the microscopic to the entire biosphere.Assessment: Students will be assessed through observation of their interactions and contributions, with incidental notes taken. The student summaries will be examined as well, and this will count towards the unit work portion of their grade. Connection to other Lessons: This lesson is intended to begin the unit and get students to think about the concept of an ecosystem. Flexible Groupings: Students will discuss the video and information presented from it as an entire class. Activating Strategies: Students will engage in a brief brainstorming session about what they think some of the key words and concepts, such as “ecosystem” and “biosphere” mean. The three Essential Questions of the unit will be introduced to the students. Acquiring Strategies: Students will watch a portion of the BBC documentary Planet Earth, being directed to watch out for signs of functioning ecosystems. Applying Strategies: Students will engage in a group discussion of the key concepts of ecosystems in relation to the video clip they have seen. Students will write a brief reflections on their reactions to the video and what they learned in it. Learning Resources: Manitoba Science CurriculumPlanet Earth DVDDifferent Ways of Learning:Interpersonal Students Intrapersonal: Students will write about their own personal reactions and learning from the video. Verbal/Linguistic: Students will engage in class discussion and write a brief summary of Visual: Students will watch portions of Planet Earth.Materials Used: Whiteboard/SmartboardLesson #2: What Is An Ecosystem?Lesson PlanMr. KeenSubject: ScienceTopic: Introduction to EcosystemsUnit: Interactions In EcosystemsGrade: Grade 7Learning Outcomes: 7-1-01: Use appropriate vocabulary related to their investigations of interactions within ecosystems. 7-1-02: Define ecosystem and describe various examples that range from the microscopic to the entire biosphere. 7-1-03: Identify abiotic and biotic components of ecoystems that allow particular organisms to survive. 7-1-04: Describe ecological succession and identify signs of succession in a variety of ecoystems. Include: The natural process whereby some species are replaced by other species in a predictable pattern.Assessment: After students do the lesson, they will engage in a game of Who Wants To Be A Science Expert?, in which students will be asked questions from the slides taken, with correct answers meaning prizes. Connection to Other Lessons:This lesson picks up immediately after the previous lesson has left off, expanding student knowledge about ecosystems considerably. Activating: Students will engage in a roundtable discussion of what was brought up last period, and then bring what they discussed to the class as a whole. Acquiring: A PowerPoint lesson will be taught, giving the students an overview of the most important themes of the unit. The lesson will be stopped periodically to check on student understanding Applying: After the PowerPoint lesson is over, the class will engage in a spirited round of Who Wants To Be A Science Expert, in which students will be put on the spot for a series of four questions. If they go through all of them correctly, they will gain a prize. The rules for Who Wants To Be A Science Expert are given below. Learning Resources: Grade 7 Interactions Within Ecosystems Notes, by Kathy Lyons, Christ the Redeemer Catholic SchoolPowerpointSmartboardFlexible Groupings: The class will engage in the lesson as a whole group, and play the game Who Wants To Be A Science Expert? Together as well. Different Ways of Learning:Interpersonal: The class will have to help each other for the Who Wants To Be A Science Expert game. Verbal: The PowerPoint presentation will be viewed as well as watched. Materials Used:Who Wants To Be A Science ExpertWho Wants To Be A Science Expert? Rules: The student has to answer five questions correctly to win. They will get a small prize for participating and another one if they succeed in answering all questions successfully. I have no objection to offering small candies as a prize, but if schools are stubborn about this or you prefer something else, use stickers or some other small and cheap item students like in your class. If the student does not know the answer to the question, they have three Lifelines: 50/50: The student eliminates two of the options, leaving the correct and one incorrect answer. Ask a Friend: The student can ask any one person in the classroom and get their feedback on an answer. Poll the Class: The student can poll the class, seeing how many raise their hands at each option. Sample Questions: A biotic part of an ecosystem is: A living part of the ecosystemA non-living part of the ecosystemA robotic part of the ecosystemA formerly living part of the ecosystemIn ecologic, consumers are the following:Creatures that shop at Wal-MartCreatures that consume energy without directly producing itCreatures that eat primarily meatCreatures that eat primarily plantsWhich of the following creatures is NOT a parasite?LeechTapewormOrchidHead LouseScavengers eat primarily the following: AnimalsPlantsCarrionRocksEcological Succession is the following:The process in which one species of apex predator replaces anotherThe process in which one part of an ecosystem separates from anotherThe process in which hippies leave urban society to live on communesThe process in which the species structure in a given ecosystem changes over timeLesson #3: Photosynthesis and Cellular RespirationLesson PlanMr. KeenSubject: ScienceTopic: Introduction to EcosystemsUnit: Interactions within EcosystemsGrade: Grade 7Learning Outcomes: 7-1-08: Compare photosynthesis to cellular respiration and explain how both are part of the cycling of matter and the transfer of energy in ecosystems.Assessment: Students will complete Blackline Master 7-B, which will be assessed by the instructor and included as part of their unit work. Connection to Other Lessons: This lesson will give more depth to the concept of energy cycling in an ecosystem and prepare the way for further discussion on the issue. Activating: Students will watch a YouTube video on cellular respiration and photosynthesis on the Smartboard. : Students will complete Blackline Master 7-BApplying: Students will be given bean seeds, which they will help in germinating and explain the needs of their growing plants using appropriate scientific terminology. Learning Resources: Flexible Grouping: Students will do their Blackline Masters individually, and they will work with their bean plants in pairs. Different Ways of Learning: Interpersonal: Students will be working in pairs to take care of their bean plants. Kinesthetic: Students will work hands-on to help their bean plants germinate. Logical/Mathematical: Students will be precisely measuring how long it takes for their plant to germinate, as well as how much water to give it. Naturalistic: Students will gain a hands-on appreciation of how the processes of cellular respiration and photosynthesis work in the natural world. Verbal/Linguistic: Students will work on and complete Blackline Master 7-B. Materials Needed: Bean Plants, bags, other appropriate materialsCopies of Blackline Master 7-BHow To Take Care of a Bean Plant You Are Taking Care Of Your Plants … Why does your plant need sunlight in order to grow?

Connection with Other Lessons: This lesson will help solidify some of the most important concepts in the minds of students and will prepare them for upcoming assignments, including one where they must make their own functioning ecosystem. Flexible Groupings: Students will complete an example of an ecological pyramid and a food web as a whole class before working individually on their worksheets. Activating Strategies: Students will walk in to hear The Circle of Life from the Lion King, for which no context will be immediately offered. Acquiring Strategies: Students will work as a class in order to complete the example ecological pyramid and food webs on the whiteboard. The ecological pyramid will be completed by questioning students, while individual students will come up to fill in links in the food web. While this is happening, the concept of bioaccumulation will be explained, as potential toxins become more and more concentrated in successive consumer levels. While an insect that a fish eats may be unharmed, the fish may be slightly harmed and the eagle that consumes the fish seriously harmed by a toxin. Applying Strategies: Students will work to complete worksheets to reinforce their learning. Learning Resources: Manitoba Science Curriculum Ways of Learning: Intrapersonal: Students will work individually to complete worksheets. Kinesthetic: Students will work hands on in making the food web at the front of the class. Musical: An appropriate song will be played to get students to think about the idea of cycling in ecosystems. Verbal/Linguistic: Students will do group discussion and writing. Visual: A Smartboard presentation will be made. Materials Needed:Computer and SpeakersWorksheets (example provided below)Whiteboard, markers, etcCreate An Ecological Pyramid: Make sure to correctly place producers, primary consumers (herbivores), secondary consumers (carnivores), tertiary consumers (apex predators), scavengers and decomposers on your pyramid! You’ll be doing this again for a much bigger assignment later on in the unit, so do your best work now! center000Food WebDraw a line from each creature to what it would eat. Indicate if it is a herbivore (primary consumer), carnivore (secondary consumer) or omnivoreLesson #6: How I Learned To Stop Being Grossed Out And Love Vultures And WormsLesson PlanMr. KeenSubject: ScienceTopic: Introductions to EcosystemsUnit: Interactions within EcosystemsGrade: Grade 7Learning Outcomes: 7-1-12: Provide examples of scavengers and decomposers and describe their role in cycling matter in an ecosystem.Assessment: Students will be assessed on the quality of reasoning and thought shown in their groupwork and their grasp of basic concepts will be uncovered through careful questioning on they work on creating the school composting system. Connection with Other Lessons: This lesson elucidates an important part of the ecosystem that is often ignored, that is, the role of scavengers and decomposers. Flexible Groupings: Students will work in table groups to come up with examples of scavengers and decomposers in an ecosystem. Activating Strategies: There will be a short Smartboard presentation on scavengers and decomposers and their role in the ecosystem, in which some of Kathy Lyon’s slides will be referenced. Students will also be shown fruit in various stages of decomposition and a composting bin (ideally one with worms). Acquiring Strategies: Students will work in table groups to come up with some examples of scavengers and decomposers and how they might be helpful to the ecosystem in which they live in (for example, how hyenas and vultures clean up remains left by lions, how scavengers often disperse seeds through their droppings, how earthworms enrich and aerate soil). Applying Strategies: Students will start a composting program in the school to allow decomposers to do their work properly within the ecosystem of the school environment. If possible, one with earthworms that works fairly rapidly would be ideal. Learning Resources: Manitoba Science CurriculumKathy Lyon’s Grade 7 Interactions within Ecosystems PowerPoint notesPlanet Earth DVDDifferent Ways of Learning: Kinesthetic: Students will be working hands-on in order to create a composting system in the school. Interpersonal: Students will be working in groups to create a food pyramid. Logical/Mathematical: Students will have to logically consider the creation of composting bins and the logistics of delivering one to each classroom. Naturalistic: Students will be coming up close and personal with elements of nature. Verbal/Linguistic: Students will be writing and communicating their examples of scavengers and decomposers orally. Materials Needed: Composting BinsWorms (hopefully)Moldy bread, rotting fruitHow to Compost: (We will be using a garbage bin or two) will give recycling bins and composting bags for free. They host a Waste Reduction School Challenge in Brandon Schools. Vocabulary Quiz #1What is an ecosystem? a.) Just the non-living things in a given areab.) Just the living things in a given areac.)

After the game is finished, there will be a brief discussion of the salient points made in the game. Connection to other Lessons: This lesson will help impress upon the students the actual workings of an ecosystem in a fun and interactive way.Flexible Groupings: This is a whole class activity, so there are no groupings as such. Activating Strategies: Preparing for LearningStudents will quickly do a KWL related to any existing knowledge or conceptions they have about the vital words and concepts that will be dealt with in the Energy Game. Acquiring Strategies: Integrating and Processing LearningA brief classroom lesson with a Smartboard Presentation will be taught to give students a working knowledge of the concepts that they need. They will be handed a copy of an ecological pyramid, with the appropriate levels placed on. Applying Strategies: Consolidating LearningStudents will play the Energy Game, in which all players are trying to Learning Resources: Manitoba Science CurruculumDifferent Ways of Learning: Intrapersonal: Students will be doing their own ecosystem checklists. Interpersonal: Students will be communicating with each other about their observations and reflections. Kinesthetic: Students will be encouraged to pick up and handle artifacts and possibly animals from the Riverbank area, though only with the permission of the tour guide. Logical/Mathematical: Students will be encouraged to keep track of what they see on their ecosystem checklists. Naturalistic: Students will be experiencing nature directly, rather than simply observing a program or hearing a lecture. Student responses to the natural environment can be captured in their reflections. Verbal: Students will be talking with each other about their observations and experiences, both on the trail (as appropriate) and in the classroom after they return. Visual: Students will be encouraged to sketch something on their checklists, whether it be a plant or an animal. Resources Used: Coloured Paper (to represent the plant energy)Stick-On Tags (for players to identify themselves) The Energy Game!All ecosystems are based upon the transfer of energy between levels, as producers are eaten by consumers and consumers prey upon each other, which energy being recycled back into the ecosystem by scavengers and decomposers. What the Energy Game tries to do is model the transfer of energy between levels in an ecosystem. Rules: (Assuming a class of 25 students) Group Composition: 18 students will be herbivores (first-tier consumers)6 students will be carnivores (second-tier consumers)2 students will be scavengersHerbivores can directly pick up food energy in the form of plants, represented by pieces of paper left around the room, some in large packs, others singly, in various locations. Only they can gather up the energy which directly fuels the ecosystem. Carnivores go around the room and engage the herbivores in a game of rock, paper, scissors, and must win 2/3 matches in order to seize the energy from the herbivore, which must find new energy. Scavengers get energy by taking energy from the predators, including the apex predator. Any energy that the scavengers or decomposers take is left in the room for an herbivore to pick up. After playing rock, paper, scissors with one other person, you must leave that person and find another person. Be fair and honest with each other. The idea with the game is that you will create a relatively self-sustaining ecosystem, with energy dynamically flowing from one to the other. While the game is going on, at any time, the teacher can remove elements from the game in order to disrupt the functioning of the system. Without herbivores, there is no energy flow because no one can actually eat the plants. Without carnivores, there is simply endless accumulation with herbivores. Scavengers make sure that energy doesn’t stay with the carnivore. Removing any one element makes it extremely difficult for the rest of the system to function. Lesson #8 Interacting with Nature: A Field Trip to the Riverbank Discovery CentreLesson PlanMr. KeenSubject: ScienceTopic: Introduction to EcosystemsUnit: Interactions within EcosystemsGrade: Grade 7Learning Outcomes: 7-1-01: Use appropriate vocabulary related to their investigations of interactions within ecosystems.7-1-05: Identify and describe positive and negative examples of human interventions that have an impact on ecological succession or the makeup of ecoystems.7-1-06: Identify environmental, social and economic factors that should be considered in the management and preservation of ecyosystems.Assessment: Students will complete ecosystem checklists, which will be assessed by the teacher. They may not be complete, but will all demonstrate signs of observation. Students will discuss their findings and observations with each other, and I will listen in on their conversations. Connection to other Lessons: This lesson will serve as a summation of their prior experiences, as they get to observe a natural habitat in its entirety, and additionally will serve as a springboard to two other lessons. Flexible Groupings: Students will be broken up into pairs, who will work together on their ecosystem checklist. These pairs will also serve as a “buddy system” for such occasions such as bathroom or water breaks, and as a basis of splitting up the group if there are too many for a given tour. Activating Strategies: Preparing for LearningBefore the field trip, students will do a brainstorming sessions on what they expect to find at the Riverbank Discovery Centre, relative to what they have been taught. Students will be primed on what to expect before they go there. Acquiring Strategies: Integrating and Processing LearningOn the walking path, students will be listening to the tour guide as they explain features of the wetlands environment as well as both positive and negative human intervention. They will be filling out their ecological checklists as well as jotting down notes for their reflection if they desire. Applying Strategies: Consolidating LearningThe whole class will briefly return to their brainstorming session before and compare what they found to what they thought they would find previously. They will be invited to discuss their findings, thoughts and connections with each other in table groups, as the instructor will go around taking notes about their findings.

While exploring the Riverbank I discovered: Evidence of ecological succession __Evidence of animal alteration to the ecosystem__Evidence of positive human intervention in the ecosystem__Evidence of negative human intervention in the ecosystem__Evidence of energy transfer in the ecosystem__A producer__A consumer (herbivorous)__A consumer (carnivorous)__A scavenger__Evidence of decomposers__Something I did not expect to find__What was it? _____________________________________________SKETCH: Mr. Keen loves to draw and he’d like you to as well! Draw an interesting creature or feature you saw at the Riverbank Discovery Centre.-666752984400Lesson #8: Reflections on NatureLesson PlanMr. KeenSubject: ScienceTopic: Human Interactions with EcosystemsUnit: Interactions within EcosystemsGrade: Grade 7 Learning Outcomes: 7-1-05: Identify and describe positive and negative examples of human interventions that have an impact on ecological succession or the makeup of ecoystems.7-1-06: Identify environmental, social and economic factors that should be considered in the management and preservation of ecyosystems.7-1-07: Propose a course of action to protect the habitat of a particular organism within an ecosystem. Assessment: Student reflections upon their visit to the Riverbank Discovery Centre will be assessed. Connection to Other Lessons: This lesson is intended as a follow-up to the field-trip that occurred in the previous session. During this class, students will also be informed about the upcoming project of creating habitats for animals and will be expected to begin looking online for ideas for creating bird shelters. Flexible Groupings:The reflection writing will be an independent-work assignment. Activating Strategies: Students will engage in a class discussion and brainstorming session regarding their visit to the Riverbank Discovery Centre. Acquiring Strategies: Students will take the content of the discussion and their notes from the visit to the Riverbank and use it to write a reflection on their trip and a proposal for themselves or a group to do something to protect a creature’s habitat, whether it be as simple as cleaning up garbage or as intensive as a tree-planting program. Applying Strategies: Students will be invited to follow through with their proposals. If any proposal here is sufficiently meritorious, the whole class might engage in making it happen. Learning Resources: Manitoba Science CurriculumThe imaginations of studentsDifferent Ways of Learning: Interpersonal: Students will engage in a class discussion about their field trip to the Riverbank. Intrapersonal: Students will be engaging in a personal reflection. Naturalistic: Students will be invited to consider an ecological perspective on all matters. Verbal/Linguistic: Students will engage in speaking during the class discussion and writing their reflections. Resources Used: Whiteboard and markersChart paperLesson #9: Creating a HabitatLesson PlanMr. KeenSubject: ScienceTopic: Human Interactions w/EcosystemsUnit: Interactions within EcosystemsGrade 7Learning Outcomes: 7-1-05: Identify and describe positive and negative examples of human interventions that have an impact on ecological succession or the makeup of ecosystems. 7-1-07: Propose a course of action to protect the habitat of a particular organism within an ecosystem. Assessment: The animal habitat that is created using this project will be a graded project, and is worth 20% of the final unit grade. In addition, students will write a self-reflection on the project. Functionality will be the most important of the criteria, with aesthetics being secondary. Connection to other Lessons: This lesson flows from the previous lesson and follows from the field trip to the Riverbank Discovery Centre. Activating Strategies: Students will engage in a discussion of habitats and form groups. They will have been told to find ideas for a habitat to create online and will make definite plans in the first class. Acquiring Strategies: Students will build shelters with their groups, being given class time to construct their habitats, but also able to take their shelters home to work on them if they desire. Applying Strategies: Students will present their habitats to a representative of Brandon Riverbank Inc., Ducks Unlimited or another appropriate agency which will come to the classroom to speak with students about their project and take their work. Flexible Groupings:Students will be able to freely choose groups for this project, with each group consisting of four to five students. Learning Resources: Manitoba Science CurriculumDifferent Ways of Learning: Interpersonal: Students will be working with each other to create a shelter. Kinesthetic: Students will be working hands-on to create a functioning animal shelter. Logical/Mathematical: Students will need to use precise measurements in order to create their shelters. Visual: Students will be decorating their animal shelters appropriately. Materials Required:Wood (of various sizes)Tools (including screws and nails, though any power tools MUST be used by the teacher)Special Note:The school shop teacher will be contacted regarding possible collaboration and assistance with any projects that require woodworking. Students will be able to use ordinary hammers and nails under supervision with proper precautions, but absolutely cannot use any power tools unless under the supervision and explicit agreement of the shop teacher. Assessment Rubric for Animal Habitats: Functionality: 1= Not Meeting Standard. The habitat created is wholly unfit or even dangerous for an animal to inhabit. 2= Approaching Standard. The habitat created is marginally fit for animal inhabitation and may require some modification before being offered to Brandon Riverbank Inc. or Ducks Unlimited. 3= Meeting Standard. The habitat created is fit for animal inhabitation and does not require modification to be offered to Brandon River Bank Inc. or Ducks Unlimited. 4= Exceeding Standard. The habitat created is innovative and provides for more than an animal’s basic needs, or the habitat is a large, ambitious model for a larger creature that meets the standard of Brandon Riverbank Inc. or Ducks Unlimited. Grade on Functionality-285757683500Aesthetics and Creativity: 1= Not Meeting Standard. The habitat shows no signs of creativity or appealing visual design. 2= Approaching Standard. The habitat shows some signs of creativity or appealing visual design. 3= Meeting Standard. The habitat created shows significant signs of creativity and appealing visual design. 4= Exceeding Standard. The habitat created displays “out of the box” thinking regarding visual aesthetics and creativity.

Lesson #12: Good Germs, Bad GermsLesson PlanMr. KeenSubject: ScienceTopic: Introduction to EcosystemsUnit: Interactions within EcosystemsGrade: Grade 7Learning Outcomes: 7-1-14: Identify beneficial and harmful roles played by microorganisms7-1-15: Research and describe human food production or preservation techniques that apply a knowledge of micro-organismsAssessment: Students will produce a brief report on one beneficial or harmful role played by microorganisms, which will be assessed. Additionally, their participation in the roundtable discussion will be assessed and incidental notes taken. Connection to Other Lessons:This lesson continues a discussion of microorganisms. Activating: Students will be treated to a snack, provided there aren’t any horrible allergies in the group. Something baked, and yogurt. Probiotic yogurt. And then we’re gonna talk about what probiotic actually means. Acquiring: A brief lesson about beneficial and harmful micro-organisms will be delivered via PowerPoint while the kids finish up their snack. There will be a subsequent discussion, where students come up with ideas for further research about beneficial and harmful microorganisms. Applying: Students will work either individually or in pairs to do a research project on one helpful or harmful role that microorganisms play in the environment. Learning Resources:Manitoba Science CurriculumDifferent Ways of Learning:Interpersonal: Students will work together in order to do their research. Kinesthetic: Students will, literally, get their hands on the product of beneficial microorganisms. They will, in fact, eat them. Verbal: Students will discuss the idea of beneficial and harmful microorganisms as a class, and then present their findings. Resources Used: Baked goods (could be toast, or a half muffin or something similar)YogurtBowls, spoons, etcMoldy bread (to demonstrate a harmful role that microorganisms play)Microorganism Research Project:Assignment HandoutYour mission, should you choose to accept it (but you should, because this is worth marks) is to find a partner if you wish and do a research project on one helpful or harmful role that microorganisms play in natural and humanmade environments. Your research project will take the ultimate form of a 1-2 page typed or written report (if you have large writing, it might be longer- I can tell) which will be presented orally. This will be a graded assignment which is worth 15% of your total unit grade. You should use more than one source for your research- while I support and heartily endorse Wikipedia as a whole, it is not a sufficient resource by itself. If I may make a humble suggestion, scroll to the bottom of a Wikipedia article and check out the links! Suddenly, your one source has become three, or five, or a dozen. There is also the possibility of finding material in a non-online source, though the library. You will be given some class time in order to do this project, but it may be necessary for you to do some work on your own time. Your project needs to explore one harmful or helpful role that microorganisms play in some detail and contain an introduction, body and conclusion, with correct sentence and paragraph structure. You will be graded on the quality of your research and content, and on the quality of your writing and organization. Microorganism Research Project Assessment RubricResearch and Content1 = Not Meeting Standard. There is little or no discernable research, and the content is significantly less than sufficient for the purposes of the assignment. (Should be 1-2 pages)2= Approaching Standard. Students used one source for research, such as Wikipedia. The content is of approximately the right length, but does not cover the material in any depth. 3= Meeting Standard. Students used 1-2 additional sources in addition to a general reference work such as an encyclopedia or Wikipedia. The content is interesting, sufficient in quantity and shows understanding of the material. 4= Exceeding Standard. Students used 3 or more additional sources and have extensive, well-researched and interesting content that show a real interest and grasp of the subject material. Grade on Research Content-1047755143500Organization and Writing1= Not Meeting Standard. There is no discernable organization (no real introduction or conclusion) and the writing is of extremely poor quality, with large numbers of spelling and grammatical errors. 2= Approaching Standard. There is a scheme of organization but it is basic and may be flawed. The writing may have several spelling and grammatical errors, but mostly be accurate and understandable. 3= Meeting Standard. There is a rational scheme of organization, introduction, body, conclusion. The writing is good, with few spelling or grammatical errors. 4= Exceeding Standard. There is a solid scheme of organization, not just introduction, body and conclusion, but also solid organization of all paragraphs. The writing is excellent, with no spelling or grammatical errors. Grade on Writing and Presentation-104774-17335500Total Grade (The average of the two grades)-1047756604000Lesson #14: Design Your Own EcosystemLesson PlanMr. KeenSubject: ScienceTopic: Introduction to EcosystemsUnit: Interactions within EcosystemsGrade: Grade 7Learning Outcomes: 7-1-01: Use appropriate vocabulary related to their investigations of interactions within ecosystems. 7-1-02: Define ecosystem and describe various examples that range from the microscopic to the entire biosphere. 7-1-03: Identify abiotic and biotic components of ecoystems that allow particular organisms to survive.7-1-09: Analyze food webs, using ecological pyramids, to show energy gained or lost at various consumer levels.7-1-12: Provide examples of scavengers and decomposers and describe their role in recycling matter in an ecosystemAssessment: This is a graded assignment, and the rubric for the assignment is provided below. Additionally, observation and incidental notes will be made throughout the completion of the project. Connection to other Lessons: This project will demonstrate the knowledge that students have gained regarding the functioning of an ecosystem. Flexible Groupings: This is a whole class activity, so there are no groupings as such. Activating Strategies: Preparing for LearningStudents will be engaged in a brief whole-class exercise to review their knowledge of the elements of an ecosystem, and will place a few examples of real-world creatures at all of the following relevant levels. Acquiring Strategies: Integrating and Processing LearningStudents will engage in group work to create an ecosystem of their own devising, using creatures they themselves have made up, in an ecosystem that can either be inspired by real-world ecosystems or totally fictional ones. Applying Strategies: Consolidating LearningStudents will engage in in-class presentations of their finished ecosystems, giving them a chance to show off their hard work and receive comments and constructive criticism from their peers. Learning Resources: Manitoba Science CurriculumDifferent Ways of Learning: Intrapersonal: Students will be doing their own individual reflections upon their project. Interpersonal: Students will be communicating with each other about their observations and reflections. Kinesthetic: Students will be working hands-on to create their posters. Logical/Mathematical: Students will be encouraged to think through the problems involved in creating an ecosystem in an organized and logical manner, including the number of predators relative to prey and similar considerations. Verbal: Students will be presenting their finished product to each other. Visual: Students will be engaged in making their posters visually attractive, as well as drawing the creatures placed upon them. Resources Used: Posterboard and Art Supplies (for the students to make their posters)Assignment Handout (Build Your Own Ecosystem)You and your group are astronauts who have just touched down on a strange planet, filled with bizarre life forms. You have been charged with the mission of discovering the workings of the ecosystem of the new planet you have landed on, with all the best instruments available to medical science and the best training a Grade Seven science class can give you … For this assignment, you will create an example of a functioning ecosystem, which must contain the following elements: Abiotic elements (soil, rocks, water, etc)Biotic elements (plants, animals, microorganisms)A food pyramid containing producers, consumers (both herbivores and carnivores), scavengers and decomposers. You will create a visual presentation of your ecosystem with appropriate captions on a piece of posterboard (this will be provided) as well as a brief (1-2 pages) writeup about the functioning of the ecosystem your group has created. All of the creatures in the ecosystem must either be your own original creation or from folklore (nothing can be used from copyrighted material like Harry Potter or Lord of the Rings) and it should demonstrate your understanding of the principles behind a functioning ecosystem. Your ecosystems will be presented in class and displayed prominently outside of the classroom. Class time will be given to complete the assignment, but it may be necessary to do some of the work for this assignment on your own time. This is an important graded assignment, worth 25% of your unit grade. Good Luck! I look forward to seeing your completed ecosystems.
