1. Activator You and a partner will compete in the great ice cube race to see who can melt an ice cube in a zip lock bag the fastest. You may not leave your area or take the ice cube out of the bag. Write as your activator how you win the race.

2. Heating Curve of water You will be given a beaker with ice water and a thermometer. When told to start read and record the temperature on your data table. Stop after your ice melts and bring your water to the front of the class.

3. Melting Description Changes from solid to liquid. Energy Change Absorbs Energy

4. Freezing Description Changes from liquid to solid Energy Change Releases energy

5. Boiling Description Changes from liquid to gas Energy change Absorbs energy

6. Condensation Description Changes from gas to liquid Energy Change Releases energy

7. Sublimation Description Changes directly from solid to gas Energy change Absorbs energy

8. Deposition Description Changed directly from gas to solid Energy change Releases energy

9. Activator Copy and Answer the questions Yesterday while the ice / water mixture was melting why did the temperature stay the same? Why did the boiling temperature stay the same?

10. Heating Curve of Water

11. Phase Changes

12. Weekly Summary 1.How did you do on the heating curve assessment? 2.Which learning activities were of the greatest value this week? 3.How could instruction been better this week? 4.Do you have any concerns with Physical Science.

13. Activator Sketch the graphs and draw the molecular motion of the water molecules for each section of the graph. I II III IVV
