25. Draw a diagram of the atoms in a Compound, Mixture, Atom and Molecule. CompoundMixture AtomMolecule

26. Draw a diagram of the atoms in a Compound, Mixture, Atom and Molecule. CompoundMixture or AtomMolecule

27. ? As thermal energy decreases, what happens to the movement of molecules?

28. Slow down/closer together As thermal energy decreases, what happens to the movement of molecules?

29. ? Which has a higher density: Copper at 28°C or Copper at 34°C? Why?

30. Copper at 28 degrees Which has a higher density: Copper at 28°C or Copper at 34°C? Why? Because it has less thermal energy, so less movement, so the atoms are closer together

31. Separating Mixtures  You are given a bucket filled with sand, rocks, iron nails, and pieces of foam.  Discuss with your partner how you would separate the pieces from each other and what equipment you would need.  No, you cannot simply pick the things out with your hands  Once you have a plan, share it with your table group to compare and decide on a final plan.

32. Separating Mixtures Just one way of doing it: 1. Use a magnet to separate the iron nails. 2. Use a grate/strainer to separate the rocks out. 3. Use water to make the foam float to the top and skim it off. 4. Boil off the water from the sand. These are all PHYSICAL methods.

46. Describe the properties of each state of matter. (Attraction, Movement, Shape, Volume, and Mass) SolidLiquid Gas

47. (Attraction, Movement, Shape, Volume, and Mass) SolidLiquid Has a definite shape and volume Molecules are packed tightly together Molecules only vibrate slightly Molecules are VERY attracted to each other Has a definite volume but no definite shape (Takes the shape of its container) Molecules are packed almost as tightly as a solid Molecules move freely around each other Molecules are somewhat attracted to each other. Gas No definite shape or volume As gas molecules spread apart, they fill all the available space. (takes on shape of container) Molecules move at high speeds in all directions Molecules not attracted to each other.
