Day 1: Wednesday, March 18, 2020 Choice 1: Use the following list of lab safety rules to draw two pictures of classroom scenarios where one picture is a lab safety rule being following and one is a lab safety rule not being followed. Never run, push, or engage in horseplay or practical jokes of any kind in the lab.Never eat, drink or chew gum in a lab.Never sit on the lab tables.Wear protective eye goggles and aprons when performing experiments or instructed by your teacher.Dress appropriately wear pants, wear closed-toed shoes, long sleeves, pull back hair and remove jewelry.Keep your desk area clean and place personal belongings away from the lab.Keep chemicals and glassware away from the edge of the table.Never touch equipment, chemicals or other materials without permission.Keep your hands away from your face, eyes, mouth and body during experiments and wash them before your leave the lab.Choice 2: Complete lab safety scenario worksheet below. Describe how each scenario could have been prevented (precautions) and how you could respond to minimize accidents (response). Scenario DescriptionPrecautionsResponseA student is working hard on a chemistry lab experiment that uses a strong acid. Halfway through the lab, the student gets hungry and starts eating a bag of chips. When the student licks their fingers, they start to have a severe reaction.During a chemistry experiment, a student carefully pours and unknown solution from a test tube into a beaker. Another student sneaks up behind them and surprises their friend. The student accidentally drops the beaker on the floor, and pieces of glass land on their sandaled feet.A student with long hair (or loose clothing) is heating a solution over a Bunsen burner. As the student leans over the burner to reach for something, their hair (or clothing) catches fire.A student is excitedly telling their friend their plans for the weekend, and is not listening to the teacher’s lab instructions. During the lab, the student mixes two of the wrong chemicals together and an uncontrolled chemical reaction occurs.Day 2: Thursday, March 19, 2020 Use the graphing notes about “TAILS” to complete one of the graphing activities below. 34486851905000Choice 1: Graphing Gizmo – download in Unified Classroom, Teams or Teacher WebpageChoice 2: Create a tally chart of the letters in the following sentence.

A graph communicates 277499155200the responding and manipulated variables tested and measured during and experiment. The manipulated variable is identified and labeled along the x, or horizontal, axis, and the responding variable is identified along the y, or vertical, axis. Graph the data Laura collected during her experiment in the empty graph provided. Number the y-axis by 20’s and label it “Average Time Soda Bubbled”. Write the substances tested under every other space along the x-axis, and then label it “Substance Tested” Use a bar graph since you are comparing times. Title the graph “Bubbling Time of Sodas with Granular Substances”. Day 7: Friday, March 27, 2020Choose one of the following activities to complete.

Day 9: Tuesday, March 31 Natural Selection WorksheetDarwin’s Natural Selection WorksheetName ___________________________________Read the following situations below and identify points of Darwin’s natural selection.5603875120650001)There are 2 types of worms: worms that eat at night (nocturnal) and worms that eat during the day (diurnal). The birds eat during the day and seem to be eating ONLY the diurnal worms. The nocturnal worms are in their burrows during this time. Each spring when the worms reproduce, they have about 500 babies but only 100 of these 500 ever become old enough to reproduce.Identify a type of variation in the worms. ______________________________________________________Which variation is most favorable? _______________________________________________________In 50 years, what will natural selection have most likely done for the worms? _________________________________________________________________________________What adaptations might occur in the birds in 100 years? ______________________________________ ________________________________________________________________________________________518160060960002) There are 3 types of polar bears: ones with thick coats, ones with thin coats and ones with medium coats. It is fall, soon to be winter. The temperatures are dropping rapidly and the bears must be kept warm, or they will freeze to death. Many of the bears have had ~2 cubs each but due to the extreme temperatures, many mothers only have one cub left.Identify a type of variation in the polar bears ______________________________________________________Which variation is most favorable? _______________________________________________________In 50 years, what will natural selection have most likely done to the polar bears? _________________________________________________________________________________15240018415003) In ostriches, there are 2 types: ones that run fast and those that run slowly. The fast birds can reach up to 40 miles an hour. Jackals love to eat ostrich, and they can reach speeds of up to 35-40 miles per hour. A flock of ostrich will lay ~ 10 eggs (each mother only lays 1), but many rodents break into the eggs and eat the fetus before they hatch.Identify a type of variation in the ostriches ______________________________________________________Which variation is most favorable? _______________________________________________________In 50 years, what will natural selection have most likely done to the ostriches? _________________________________________________________________________________#4: A population of insects is sprayed with a new insecticide. Most of the insects are killed but a few survive. In the next generation, many more of the insects are unaffected by the insecticide. Which of the following BEST explains these results?The insecticide caused a mutation in the species.A few insects in the first population were immune and passed this trait to their offspring.The insecticide caused a side effect of immunity that was passed on to the next generation of insects.The insects learned to fight off the insecticide.What adaptation might occur in the jackals in 100 years? ______________________________________________________4924425-222885005) There are two types of rabbits: those that strictly eat grass and those that strictly eat berries and flowers. A drought occurs one year, and the plants have difficulty producing any extras (flowers, berries, etc.).They can only try and keep themselves green. The rabbits have had babies all year long but many are eaten by foxes or hawks Due to the drought, many have starved to death.Identify a type of variation in the rabbits. ______________________________________________________Which variation is most favorable? _______________________________________________________In 50 years, what will natural selection have most likely done to the rabbits? ________________________________________________________________________________6)Describe how natural selection is occuring in the image above. Be sure to use the word adapt and variation: __________________________________________________________________________________________ ____________________________________________________________________________________________________________________________________________________________________________________7. The table below describes four types of female mice that live in a beach area with mostly tan sand and scattered plants. Which of the four mice types would be considered most favorable for natural selection? Explain: _______________________________________________________________________________________ ______________________________________________________________________________________________Color of furAge at Death# of mice produced by each femaleRunning speedBlack2 months08 cm/secTan7 months116 cm/secTan-Black mix8 months37 cm/secCream2 months05 cm/secDue to natural selection, what could you expect to occur to the mice on this beach over several years? _________________________________________________________________________________________________8)Snowy owls are beautiful white owls that live in the arctic. They are able to withstand the frigid temps of the arctic. They usually migrate south to southern Canada during the middle of the arctic winter, but soon return far north. Explain how the population would respond in the following scenario:a)The snowy owls environment is warming up very quickly and going from very frigid temperatures to very warm. This change is happening so quickly that the snowy owls are too visible to their prey since there is less snow. They have started having a hard time finding food and many are starving. The warmth has also messed up their migration/breeding patterns. _______________________________________________________________________________119255512400Day 10: Bird Beak Lab903951350323800 ................
