In this unit of study, students demonstrate an understanding of observable properties of materials through analysis and classification of different materials. The crosscutting concepts of patterns, cause and effect, and the influence of engineering, technology, and science on society and the natural world are called out as organizing concepts for these disciplinary core ideas. Students demonstrate grade-appropriate proficiency in planning and carrying out investigations and analyzing and interpreting data. Students are also expected to use these practices to demonstrate understanding of the core ideas.Student Learning ObjectivesPlan and conduct an investigation to describe and classify different kinds of materials by their observable properties.

Simple tests can be designed to gather evidence to support or refute student ideas about causes. Different properties are suited to different purposes. Because there is always more than one possible solution to a problem, it is useful to compare and test designs.Students who understand the concepts can: Design simple tests to gather evidence to support or refute student ideas about causes. Analyze data from tests of an object or tool to determine if it works as intended. Analyze data obtained from testing different materials to determine which materials have the properties that are best suited for an intended purpose. (Assessment of quantitative measurements is limited to length.) Examples of properties could include: Strength Flexibility Hardness Texture Absorbency Analyze data from tests of two objects designed to solve the same problem to compare the strengths and weaknesses of each. What It Looks Like in the ClassroomIn this unit of study, students look for patterns and cause-and-effect relationships as they describe and classify materials using physical properties. In addition, students collaboratively plan and carry out investigations and analyze and interpret data in order to determine which materials are best suited for an intended purpose. In the natural world, different types of matter exist, and all matter can be described and classified according to physical properties. To begin this units progression of learning, students plan and conduct investigations to describe different kinds of material using observable properties. They will collect data during these investigations; analyze the data to find patterns, such as similar properties that different materials share; and use the data to classify materials. Materials can be classified by color, texture, hardness, flexibility, or state of matter. For example, students can explore hardness of rocks by shaking them in containers to see how easily they break apart. They can explore viscosity by pouring a set amount of various liquids, such as glue, oil, and water from one container to another to observe the relative speed that each flows. Students can also heat or cool a variety of materials, such as butter, chocolate, or pieces of crayon, in order to determine whether or not these materials can be either solid or liquid depending on temperature. Because every human-made product is designed by applying some knowledge of the natural world and is built using materials derived from the natural world, it is important that students understand that different properties are suited to different purposes. After investigating and classifying a variety of materials based on their physical properties, students will engage in the engineering design process. Students can work collaboratively, with adult guidance, to test different materials to determine which have properties that are best suited for an intended purpose. For example, this project could be launched using the childrens story, The Three Little Pigs. After reading the story, students would: Investigate the physical properties of straw, sticks, and bricks in order to determine what properties make bricks the material best suited for building a house. Work together to brainstorm a list of possible structures that could be built with different materials. For example, students could build bridges or simple roller coasters for marbles. Select one structure from the list and determine the intended purpose of that structure. Select two or three different materials that could be used to build the structure. Investigate the physical properties of the materials, including shape, strength, flexibility, hardness, texture, or absorbency. Collect and analyze data to determine whether or not the given materials have properties that are suited for the intended purpose of the selected structure. In groups, use one of the materials to build the structure. (Teachers should have different groups use different materials.) Test and compare how each structure performs. Because there is always more than one possible solution to a problem, it is useful to compare the strengths and weaknesses of each structure and each material used. Integration of engineering In this unit, students investigate the physical properties of a variety of materials, and then build a structure with materials that are best suited for the structures intended purpose. This process is outlined in greater detail in the previous section. Connecting with English Language Arts/Literacy and MathematicsEnglish Language Arts The CCSS for English Language Arts can be incorporated in this unit in a number of ways. Students can participate in shared research, using trade books and online resources, to learn about the properties of matter. As students explore different types of materials, they can record their observations in science journals, and then use their notes to generate questions that can be used for formative or summative assessment. Students can add drawings or other visual displays to their work, when appropriate, to help clarify their thinking. To teach students how to describe how reasons support specific points an author makes in a text, teachers can model the comprehension skill of main idea and details using informational text about matter. Technology can be integrated into this unit of study using free software programs (e.g., Animoto) that students can use to produce and publish their writing in science. Mathematics Throughout this unit of study, students have opportunities to model with mathematics and reason abstractly and quantitatively. During investigations, students can collect and organize data using picture graphs and/or bar graphs (with a single-unit scale). This can lead to opportunities to analyze data and solve simple put together, take-apart, and compare problems using information presented in these types of graphs. Some examples of ways to sort and classify materials in order to create graphs include: Classifying materials as solids, liquids, or gases. Classifying materials by color, shape, texture, or hardness. Classifying materials based on what they are made of (e.g., wood, metal, paper, plastic). Classifying materials based on potential uses. With any graph that students create, they should be expected to analyze the data and answer questions that require them to solve problems. Modifications(Note: Teachers identify the modifications that they will use in the unit. See NGSS Appendix D:  HYPERLINK "http://www.nextgenscience.org/sites/ngss/files/Appendix%20D%20Diversity%20and%20Equity%206-14-13.pdf" All Standards, All Students/ HYPERLINK "http://www.nextgenscience.org/appendix-d-case-studies" Case Studies for vignettes and explanations of the modifications.) Structure lessons around questions that are authentic, relate to students interests, social/family background and knowledge of their community. Provide students with multiple choices for how they can represent their understandings (e.g. multisensory techniques-auditory/visual aids; pictures, illustrations, graphs, charts, data tables, multimedia, modeling). Provide opportunities for students to connect with people of similar backgrounds (e.g. conversations via digital tool such as SKYPE, experts from the community helping with a project, journal articles, and biographies). Provide multiple grouping opportunities for students to share their ideas and to encourage work among various backgrounds and cultures (e.g. multiple representation and multimodal experiences). Engage students with a variety of Science and Engineering practices to provide students with multiple entry points and multiple ways to demonstrate their understandings. Use project-based science learning to connect science with observable phenomena. Structure the learning around explaining or solving a social or community-based issue. Provide ELL students with multiple literacy strategies. Collaborate with after-school programs or clubs to extend learning opportunities.

Research on Student LearningN/A Prior LearningKindergarten Unit 1: Pushes and Pulls (engineering practices) A situation that people want to change or create can be approached as a problem to be solved through engineering. Asking questions, making observations, and gathering information are helpful in thinking about problems. Before beginning to design a solution, it is important to clearly understand the problem. Designs can be conveyed through sketches, drawings, or physical models. These representations are useful in communicating ideas for a problems solutions to other people. Future LearningGrade 5 Unit 1: Properties of Matter Measurements of a variety of properties can be used to identify materials. (Boundary: At this grade level, mass and weight are not distinguished, and no attempt is made to define the unseen particles or explain the atomic-scale mechanism of evaporation and condensation.) Matter of any type can be subdivided into particles that are too small to see, but even then the matter still exists and can be detected by other means. A model showing that gases are made from matter particles that are too small to see and are moving freely around in space can explain many observations, including the inflation and shape of a balloon and the effects of air on larger particles or objects. The amount (weight) of matter is conserved when it changes form, even in transitions in which it seems to vanish. Grade 5 Unit 2: Changes to Matter When two or more different substances are mixed, a new substance with different properties may be formed. No matter what reaction or change in properties occurs, the total weight of the substances does not change. (Boundary: Mass and weight are not distinguished at this grade level.)
