Wind Lab
Why do you think hot air rises?
Hot air rises because it has a lower density than cool air and gasses with higher densities sink.

When the fire burned out the cool air lifted the warm air up along with the remaining flakes of the tea bag.
Conclusive Questions
1. Conduction is when heat is transferred through direct contact. In this lab when the lit match touched the tea bag and the bag caught fire, that simulated conduction.
2. Convection is where the more dense cool air sinks and pushes up the warm air. In the lab, convection was simulated when the tea bag burned out and the cool air pushed the warm air, along with the remnants of the tea bag, upward.
3. Cold air is denser than hot air and it affects its motion because the denser cold air will sink while the less dense warm air gets pushed up.
4. Conduction is displayed while cooking soup because the hot stove heats up the soup. Convection happens in the soup and in the air around it.
5. To escape a burning building, you should go down because cool air sinks.
