    stand up and students on one side are "red", doing the wave very slowly.
    The next row of students are "orange" and do the wave a little faster, and
    on until the last row are "violet" and waving fast and furiously! It's
    fun, expands a little teenager energy and students often remember this
    activity during a quiz or test.

    This is an interesting idea for the kinesthetic learner, but seems like it
    could confuse the issues of wave frequency and wave speed.
    How do you/can you distinguish them?

    --If the rows are equal length, could you ensure that all rows use the same
    amount of time to "do their wave", but some rows get to repeat the process?
    This seems like a good way to discuss frequency. This has the added
    advantage of keeping distance and time the same (the two variables involved
    in speed).
