Do the Waves Move the Boat?

4-PS4-1 Develop a model of waves to describe patterns in terms of amplitude and wavelength and that waves can cause objects to move.

Sound can make matter vibrate, and vibrating matter can make sound.

Waves, which are regular patterns of motion, can be made in water by disturbing the surface. When waves move across the surface of deep water, the water goes up and down in place; there is no net motion in the direction of the wave except when the water meets a beach.

Waves of the same type can differ in amplitude (height of the wave) and wavelength (spacing between wave peaks).
