Part 2 Activity 3: Airstream Bubbles
Record the temperature of the elements in your obstacle course.
Record the temperature of the elements in your obstacle course.
1. How were the bubbles affected by the temperature of the obstacles?
When the bubbles flew across the ice, they immediately sank. Cold air has more density, so when the bubbles came across it, they sank. When the bubbles had gone across the hot plate, they rose. Warm air rises, so when the bubbles came in contact with it, they rose.
2. If the bubbles represent an air mass, how does temperature affect air masses?
When an air mass will meet cold temperature, it will sink. When an air mass meets warm temperature, it will rise.
3. What might happen to an air mass flowing over a sun-heated desert?
If an air mass meets a hot desert, then the air mass will rise because warm air rises.
4. What might happen to an air mass flowing over a cold ocean?
If an air mass meets a cold ocean, then the air mass will sink because cold air has more density and it will sink.
