An interactive simulation that teaches about periodic motion, simple harmonic motion, and conservation of energy. Observe one or two pendulums to determine how the swing is influenced by the length of the string, the mass of the pendulum...

Virtual laboratory provides five hands-on experiments at rigid pendula.

In this lesson plan students are "given one hour to solve a problem that a has caused a huge drop in sales" for a clock company. All clocks are five minutes slow. Because of this, they must find a way to put the clock back on time...
