1. Make waves of different sizes.
Use the Wave Simulator to make waves of different sizes. Look at how each affects a boat at rest, in an area with no current. Use the toolbar to change the wave height, or how tall waves are. Use the toolbar to change the wavelength, or how far apart the waves are. Use the toolbar to change the wave period. How do those changes affect the waves? How do they affect the boat?
2. Talk about the experience.
What did you have to change to make the waves bigger? Smaller? Faster? Slower? What did you have to change to make lots of waves? A few?
What is wave height?
Wave height is how tall waves are.
