Science - Grade 7 Summer PacketThis summer, you will complete TWO activities below to get you thinking scientifically.All students must complete this:Read a book about a science topic that interests you. Write a journal entry telling what the book was about and what you learned from it on the attached sheet.AND ONE of these options:Visit a museum exhibit related to science. You may also visit a nature center. Write a journal entry describing what you saw and what you learned from it.Do one of the attached science experiments. Write a journal entry explaining what you did and what you learned from it.Please print out the worksheets that correspond to the work you have chosen. Complete all work on the worksheets. You DO NOT have to print out all pages, only the ones you have chosen to complete.You can attach more sheets as needed.Name:7th Grade Class:What to do: Go to a library. Find the section of science books for kids (ask a librarian if you need help!). Choose a book that interests you AND is related to one of the following 7th grade science topics:Atoms and MoleculesChemistryPhysicsSpace ExplorationElectricity and MagnetismSimple MachinesEngineeringLook at a few different books before choosing one. Read the first page or two to make sure the reading level is not too easy or hard for you. Check out the book, then take it home and read it. Write a journal entry answering the questions below.Title of Book:Author:Year of publication:What did you learn from this book? Focus on the big ideas, not the details.What is the most interesting thing you read about in this book? Include details from the book to support your answer.In what ways does this book relate to you and your life? Use supporting details from the book.Would you recommend this book to a friend? Why or why not?Name:7th Grade Class:Visit a Scientific Institution!What to do: Visit a museum or nature center such as the Greenbelt Nature Center, American Museum of Natural History, Liberty Science Center, New York Hall of Science, Bronx Zoo, Brooklyn Botanical Gardens, etc. If you are not in New York City this summer, find a similar exhibit or nature center in the place where you are. Choose one exhibit that you find really interesting, and write a journal entry answering the questions below. Please attach a ticket stub, photo or other evidence that you visited the institution. A photo would be great so we can post them in the classroom.Which institution did you visit?When was your visit?What did you see and do?What did you learn (focus on the big ideas, not just a list of details)?If you were going to design an exhibit for this institution, what would design and why?Name:Experiment 17th Grade Class:Experiment 1(Chemistry): SolutionsBackground: A solution is a mixture of two or more substances that are evenly mixed. Every sample of a solution has the same amount of each of the substances. Examples of solutions are salt water, sugar water and soda. You know that a substance has dissolved when it seems to "disappear" into the water. If the substance has a color (like lemonade mix), the solution will all be the same color when the substance has completely dissolved. To read more about solutions, look here:: How does water temperature affect the time it takes a substance to dissolve?What is your hypothesis?Materials:At least three of the following substances: instant coffee crystals, sugar, salt, lemonade or iced tea mix (you will need a few spoonfuls of each)Measuring cupSpoonTimer, stopwatch, or clock with a second hand3 mugs or small bowls of the same size & shapeKettle or other method of heating water safely (use oven mitts if water is hot!)RefrigeratorProcedure: Read all directions before you begin!Place a cup of water into the refrigerator for at least 10 minutes before you begin. Start heating water at the same time. Leave a cup of water on the counter to bring it to room temperature. You will need three different temperatures of water- cold, room temperature, and hot.Measure a certain amount of room temperature water and pour it into one of your cups.Measure the same amount of cold water and pour it into another cup. Measure the same amount of hot water and pour it into a third cup.Quickly measure one spoonful of your substance (coffee, sugar, salt, or lemonade) and pour it into the first cup. Repeat using the same amount and the same substance in the other two cups.Start your timer. If you have someone to help you, it would be even better to drop the substances into the three cups at the same time.Observe the three cups. Do not move them or stir the water. When all of the substance seems to "disappear," you will know it has dissolved.In the data table, record how long it takes for the substance to dissolve in each sample of water.Repeat steps 1-6with a second substance. See if you get the same results!Data Chart:SubstanceTime to dissolve in cold water (seconds)Time to dissolve in room temp water (seconds)Time to dissolve in warm water (seconds)Analysis:How did the temperature of the water affect how fast the substances dissolved? Use data to support your pare your hypothesis to what really happened? Was your hypothesis supported? Use data to support your answer.How could this experiment help you make iced coffee if you are in a hurry? Explain your answer using data from your experiment.Name:Experiment 27th Grade Class:Experiment 2 (Biology): Seed GerminationBackground: Germination is the process of a seed starting to grow. The first sprouting of the seed shows you germination is taking place. To learn more about germination, look here: : How does temperature affect seed germination?What is your hypothesis?Materials:3 clear plastic or glass cups of the same size and shape3 paper towels, folded in halfWaterAt least 15 seeds- you can buy seeds or use dried beans from the supermarket- if you want to compare different types of plants, you should have at least 15 seeds of each kindThree places that have different temperatures but are otherwise similar (same amount of light, etc.) where you can put your seeds for several days (example: freezer, refrigerator, closet)Plastic wrapThermometer (optional)Procedure: Read all directions before you begin!Fold each piece of paper towel in half. Dip them in water until they are moist but not dripping.Place one folded paper towel on the inside of each cup so that it lines the sides of the cup.The folded side of the paper towel should be at the bottom of the cup."Plant" at least five seeds in each cup. Place the seeds between the layer of paper towel and the side of the cup, so that you can see the seeds. Spread out the seeds around the sides of the cup.Cover each cup tightly with plastic wrap so the water won't evaporate away.Place each cup in a different location. The locations should be different in temperature, but similar in other ways. For example, if one location is dark, the other locations should also be dark.If you have a thermometer, measure and record the temperature of each location every day.Leave the cups for at least 7 days. Each day, look at the cups. Write and draw your observations of the seeds in the table below. How many have sprouted? How long are the sprouts? Are there leaves?Set Up Details:Where did you put the seeds?Coldest location:Medium location:Hottest location:What type of seeds did you use?Data Chart:DayColdest TemperatureObservationsMedium TemperatureObservationsHottest TemperatureObservations1234567Analysis:How does temperature affect seed germination? Support your answer using data and observations.Was your hypothesis supported? Explain your answer using data from your experiment.How could this experiment help you if you want to plant a garden? Support your answer with data.Name:Experiment 37th grade class:Experiment 3 (Biology): Heart RateBackground: Your heart is a muscle that pumps blood around your body. Blood carries oxygen to your cells, and carbon dioxide away from your cells. When you exercise, your cells use more oxygen. You breathe faster and your heart beats faster as your heart tries to send more oxygen to your cells. To read more about your heart, look here: : How does exercise affect people's heart rates?What is your hypothesis?Materials:At least five friends, all about the same age. Try to find some who exercise a lot and some who exercise very littleStopwatch or other timerA place where you can run around for several minutesProcedure: Read all directions before you begin!Interview each volunteer about how much they exercise in a week and what type of exercise they do. Record their responses in your data table.Ask all volunteers to sit down.Have each volunteer use two fingers to find his/her pulse on the inside of the wrist or the side of the neck.Time for 1 minute while each volunteer silently counts his/her pulse. Record their results under “Heart rate before exercising”.Now ask each volunteer to walk at a normal pace for five minutes. After five minutes, have them measure their pulse again. Record under " Heart rate after walking”.Ask each volunteer to walk at a fast pace or run for five minutes. After five minutes, have them measure their pulse again. Record under " Heart rate after running”Have the volunteers sit for 10 minutes to cool down from exercise. Then measure their pulse again. Record under " Heart rate after resting after exercise”.Data Chart:VolunteerExercise Habits - What kind, how often, how long?Heart rate before exercising (beats per minute)Heart rate after walking (beats per minute)Heart rate after running (beats per minute)Heart rate after resting after exercise (beats per minute)12345Analysis:What is the relationship between amount a person exercises and heart rate? Support your answer using data from your experiment.Is your hypothesis supported? Use data to support your answer?How could this experiment help you advise your friends about exercise? Support your answer using data from your experiment. ................
