• 1. Provide students with a key.
    Write the following key on the board for students to refer to as they complete the activity:
    crest = top of wave
    wave trough = lowest point between each crest
    wave height = distance between crest and trough
    wavelength = distance from crest to crest or trough to trough

    2. Have students experiment with creating waves of different sizes.
    Have students use the Wave Simulator interactive to shape waves and see how they affect a boat at rest, in an area with no current. Model for students how to adjust the wave height, wavelength, and wave period and how to recognize how those changes affect the waves and boat. Then have students use the interactive in pairs.

    3. Have students reflect on their experience.
    First, ask pairs to describe how they used the interactive. Then ask: 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?
