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

This activity demonstrates liquefaction, the process by which some soils lose their solidity during an earthquake.

In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

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 conduct an experiment to find out if steel wool will weigh more or less when it is burned. Learners will explore the effects of oxidation and rusting on the steel wool.

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

In this weather-related activity, learners make a portable cloud in a bottle.
