Air and Water Compression (Type A)
A FUN WAY OF LEARNING THE NATURE OF AIR AND WATER, FOCUSING ON THE RELATIONSHIP BETWEEN VOLUME AND PRESSURE
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 power of pressing. Learn the elasticity of trapped air and water.
Method
● 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.
Learning Results
● Understand that compressing the trapped air reduces the volume, but increases the force of pressing back.
● Understand that the trapped air is compressed while the water is not compressed.
