In this physics activity, learners construct a small-scale version of a classic carnival game.

In this activity, learners build a simple mechanism that regulates the "escape" of energy released by a falling weight by portioning it into discrete amounts.

In this activity, learners burn a peanut, which produces a flame that can be used to boil away water and count the calories contained in the peanut.

In this activity, learners build a Wilberforce Pendulum, a special coupled pendulum in which energy is transferred between two modes of vibration, longitudinal ("bounce') and torsional ("twist"), on a

In this activity, learners explore how two cylinders that look the same may roll down a ramp at different rates.

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.
