Playing with Air Pressure

•What was the point of this activity?
Demonstrate the properties of air pressure and how force and area can impact the pressure of an object.
•Explain how you would introduce this to your class.
The students will predict what is going to happen if they placed their hand in the jar with/without covering the hole. Students will then use the Glove in the jar to test if they predicted it correctly.
•Where do you see a student having difficulty with this?
Understanding the scientific principles behind this experiment.
•What changes or extensions could you do to this activity?
-Allow students to partly cover the hole and predict what will happen
– Have students place their hand partly into the jar and cover the hole and predict what occured
Scientific Principles
When placing your hand in the jar with the hole uncovered it is easier to move around due to the same amount of pressure inside and outside of the jar. Once the hole is covered, the pressure increases causing it harder to move your hands inside the jar.
