1. Learning Target I can explain how thermal energy impacts molecules Investigating the relationship between temperature and pressure Take out a piece of paper and your energy project proposal.

2. Investigating the relationship between temperature and pressure Impact of Pressure on Temperature Title Purpose Independent Variable Dependent Variable Data Table Graph Summary

3. Materials: water bottle pressure cap LCD thermometer

4. How changes in pressure affect temperature 1.Place the thermometer in the water bottle and screw on the pressure cap. 2.Record starting temperature. 3.Quickly add 10 pumps of air to the bottle. 4.Record temperature. 5.Repeat steps 3 and 4 ten times. 6.Once 100 pumps of air are in the bottle, quickly unscrew the cap, observe what happens and record temperature. 7. Graph results and write a paragraph summary.
