  1. Eureka #51 • What is matter? • Give 3 examples.

  2. Answer: • Anything that is made of molecules and takes up space i.e. desk, water, air

  3. Eureka # 52 • What is meant by the term mass? • What is meant by the term volume?

  4. Answers: • Mass - a measure of the amount of matter in an object (i.e. a tree has more matter than a leaf) • Volume – a measure of how much space an object takes up

  5. Eureka #53 Name the 3 phases (states) of matter that naturally exist on the planet Earth. What determines the phase of matter of an object?

  6. Answer: • solid, liquid, and gas • Temperature determines the phase matter is in. ie. water - heat = solid (or ice) water + heat = gas(water vapor)

  7. Eureka #54 • What are the characteristics of each state of matter? (definite volume? definite shape?)

  8. Answer: Definite Volume Definite Shape Solid yes yes Liquid yes no Gas no no

  9. Eureka # 55 How do the molecules of solids, liquids, and gases differ from each other?

  10. Answer: • Solid - closely packed molecules; cannot move around much • Liquid - molecules are close together; can move around slowly • Gas - molecules are widely separated; move around freely and at high speeds

  11. Eureka #56 • State the changes in states that require heat energy to be absorbed (added).

  12. Answer • Solid to Liquid • Liquid to Gas

  13. Eureka #57 • State the changes in phase of matter in which heat energy is given off.

  14. Answer • Liquid to solid • Gas to liquid

  15. Eureka #58 • Define malleable and ductile. • List 5 properties of a metal and 5 of a nonmetal.

  16. Answers Malleable - capable of being shaped or formed; can be hammered, rolled, or pressed into shapes Ductile - can easily be bent or twisted into wire, or hammered thin

  17. NONMETALS METALS

  18. METALS: 1. Conduct heat and electricity 2. Shiny/metallic luster (look polished) 3. Silver-gray color (except copper and gold) 4. Are ductile - make wires 5. Are malleable - can be shaped into different forms NONMETALS: 1. Poor conductor of heat and electricity 2. No luster (dull appearance) 3. Brittle (breaks easily) 4. Not ductile 5. Not malleable

  19. CONGRATULATIONS!!! WE HAVE FINISHED ALL 58 Eurekas!! Bring your Eureka notebooks home today and stash them in a safe place for next year!! Remember . . . Every little bit will help when preparing for the NJASK 8 next year, so be sure to study all of your hard work from this year.
