This simple Pendulum provides an ideal introduction to harmonic motion, sound and waves. The concepts of cycle, period, frequency, and amplitude are intuitively illustrated.
Advanced activities explore extrapolation, rate of change, and functions.
The length of the string can be varied from 15 cm to nearly a meter. The Pendulum is a great example of oscillating motion but also of learning to use variables, rates of change, and graphing. 21 pages of hands-on Activities at all three levels with 41 solved questions and problems.
