WIND WAVES

How Are Waves Made?

MATERIALS

large, shallow cake pan

tap water

drinking straw

PROCEDURE

I. Fill the cake pan with tap water.

2. Hold one end of the drinking straw close to the water.

3. Blow air through the straw on the water's surface, sometimes blowing hard and sometimes softly. What happens as you blow on the water?

EXPLANATION

By blowing on the water, you produced waves on the top of the water. The energy of the air pushes the water, creating waves. This energy increases as the speed of the air increases. The height of the waves changes according to the amount of air blowing on the surface. As the energy passes through the water, ripples of waves move through the water.
