1. Observe what is presented in the photograph. Sketch the waves as seen from above the water basin Label the source of the disturbance

2. Make a paper boat. Place it in the middle of the basin. Tap the water that surrounds the paper boat then observe. Answer the guide questions below.

A. Do the waves set the paper boat into motion? What is required to set an object into motion?

B. If you exert more force in creating periodic waves by tapping the surface with greater strength, how does this affect the movement of the paper boat?

3. Sketch the water waves as seen them from above the basin. One wavelength should be labeled in the drawing.

4. Tap the water rapidly to increase the rate of the vibration. What happens to the wavelength of the waves? Sketch the water waves as seen from the top of the basin.

5. Discuss the steps in determining the speed of a wave. Please refer to the performance rubric below.
