In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.

This activity guide includes instructions on how to build a "Shake Table" by mounting an eccentric mass (off center) on the shaft of a small dc motor.

In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

In this activity, learners create a model using metric measuring tapes and atmosphere composition data.

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