Air & Water Compression - Model D

Investigate the nature of air and water, when the force of pressing is applied to trapped air or water, learn the relationship between volume change and the force of pressing, learn the elasticity of trapped air and water.

• Use water guns and syringes to check the volume and response when air or water is pushed in.
• Compare the difference with a water gun using an air gun.
• Examine the structure of the fountain using the properties of air and water.

• Understand that compressing the trapped air reduces the volume, but increases the force of pressing back.
• Understand that the trapped air is compressed, and the water is not compressed.
