1. Matter Unit Assessment Review Oct. 5, 2015

2. #1. 10 physical properties 1. size Density Mass Volume Physical state Magnetism Temperature Color shape

3. #2. change physically Lemonade Folded paper Saltwater Melted ice Paper clips and marbles

4. #3. change chemically 1. baked cake 2. burned wood 3. baking soda and vinegar 4. rotten eggs 5. leaves turning color

5. #4. mixture Definition: 2 or more substances (things) mixed together but can still be separated 1. trail mix Salad Halloween candy

6. #5. ways to separate mixtures Wood and rice: sieve / tongs /hands Water and sand: filtration / coffee filter Water and salt: evaporation (heat - 100°C) Iron filings and sand: magnet (magnetism)

7. #6. solution One substance dissolves into the other when mixing

8. #7. solution also a mixture Because it is two or more substances mixed together

9. #8. solubility The ability of one substance to dissolve into another

10. #9. properties change No, only the particles of one of the substances dissolve Ex: water and salt

11. #10. 2 examples of substances Sugar / salt evaporation

12. #11. why doesn’t the mass change The mass doesn’t change because the particles of the sugar or salt are still part of the mixture / solution

13. #12. mass and volume The density is determined How much “stuff” (matter) is in a certain amount of space

14. #13. Do not do

15. #14. describe a solid

16. #15. describe a liquid

17. #16. describe a gas

18. #17. define volume The amount of space that an object takes up

19. #18. list tools Metric ruler Graduate cylinder

20. #19. do not do

21. #20. define mass How much “stuff” (matter) is in a certain amount of space

22. #21. tools for mass TBB

23. #22. define weight The pull of gravity on an object - force

24. #23. tool for weight Spring scale

25. #24. define density How tightly packed the particles of an object are

26. #25. explain evaporation Heat is added to water to cause evaporation

27. #26. draw the cycle of solid, liquid, gas Heat is added for melting 0°C Heat is taken away for freezing 0°C Heat is added for boiling 100°C
