Objective:To determine how fluids (gases and liquids) travel between systems of different pressures. Materials: . Tea candle . A tall jar / glass . A wide bowl or deep plate . Water (with food coloring added) Instructions: 1. Fill the bowl with water. 2. Light the candle and place it on top of the water so that it floats. 3. Put the jar over the candle such that the candle is in the jar and the rim of the jar is touching the bowl. 4. After ten seconds, remove the jar. **** After reviewing the video, answer the following questions. **** Observations: State three observations from when the jar was placed over the lit candle until it was removed. a. b. C.11:01 all '6' I = AA 8 ixythoscontent.blackboardcdn.com C', Observations: State three observations from when the jar was placed over the lit candle until it was removed. a. b. C. Analysis: I. 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). a. b. C. Questions: I. Is it more likely to rain during a lowpressure 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
