Observations:

State three observations from when the jar was placed over the lit candle until it was removed.

a. Water rised

b. Bottle got foggy/ smokey

C. Fire dimed before going all the way out.

Analysis:

1. In the beginning of the video when the candle was not lit, what conclusion can you draw about the air pressure inside of the jar and outside of the jar?
2. For each of the observations above, explain how /why the changes in air pressure caused the phenomenon to occur(compare the pressures inside the jar and outside the jar).

d.

b.

C.

Questions:

1. Is it more likely to rain during a low-pressure system or a high-pressure system? Why?
2. Let us say you blow up two balloons then hold one in each hand, six inches apart from each other. If you were to blow very hard into the space between the balloons, they would move toward each other. Why?

Next Steps:

If you could modify this experiment, what would you change to further investigate the effect of high/low pressure systems?
