Matter Unit Assessment Review Oct. 5, 2015

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

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

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

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

#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)

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

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

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

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

#10. 2 examples of substances Sugar / salt evaporation

#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

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

#13. Do not do

#14. describe a solid

#15. describe a liquid

#16. describe a gas

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

#18. list tools Metric ruler Graduate cylinder

#19. do not do

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

#21. tools for mass TBB

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

#23. tool for weight Spring scale

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

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

#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
