1. GRAPH- Inquiry 4 Density of air

2. Directions: 1.Finish calibrating thermometer (steps 9 and 10) 2. Everyone should have completed Qs 4 and 5 on lined paper and STAPLED it to the Inquiry 5: lab sheet. 3. Pick one group members paper to continue questions 6, 7, 8, 9, 10, 11. Discuss these Qs and answer as a group. TRADE OFF WRITERS. These conclusion Qs will be a group grade. Write in PEN. 4. Collaborate and compare your graphs (respiration of fish). On the back of the graph, in PEN: - Interpret your graph- What does it tell us? Include details. - Write about your OWN graph

4. CONTENT BLAST! - Temperature and Density SOLIDLIQUIDGAS I. Describe how the motion of the particles and the density of a substance change as it is heated. HOMEWORK DISCUSSION- STATES OF MATTER… 2 ways the states of matter differ from each other?

5. Looking at the visual, can you explain why ice floats on water? Use the word density in your answer.

6. II. Temperature - measure of the ____________ of the molecules of a substance. _______ temperature = more _______energy movement higherkinetic

7. III. Matter is ALWAYS in motion… LIQUIDGASSOLID How does the motion of solids, liquids, and gases compare to each other?

8. A.When matter (solid, liquid, gas) is ________ atoms move ________ and spread out = EXPANSION - Volume ___________, Density ___________ HEATED FASTER INCREASESDECREASES

9. B.When matter (solid, liquid, gas) is ________ atoms move _______ and closer to each other = CONTRACTION - Volume ___________, Density __________ COOLED SLOWER DECREASESINCREASES

10. Liquid nitrogen = -320°F = VERY COLD!

11. C.______ remains constant, regardless of temperature. The ________ changes, which affects the _________. MASS VOLUME DENSITY

12. IV. _______ = is the transfer of thermal (heat) energy from a hotter to a colder object. A. _______ = the absence of heat (lack of molecular motion) HEAT COLD
