In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.

In this activity, learners turn an ordinary metal coat-hanger into a (very quiet) musical instrument.

This is a chemistry lab activity about solutions (page 7 of the PDF). Learners see firsthand how chemicals in a solution can combine to form an entirely different substance.

This is a quick activity/demonstration that introduces learners to the concept of index of refraction. Learners place stirring rods in a jar of water and notice they can see them clearly.

In this activity, learners construct a coastal landmass from sand and add features such as tidal creeks and barrier islands.

In this activity, learners use a pneumatic trough (see related activity) to generate and collect pure oxygen.

Visitors test solutions of water, sugar, salt, and hydrochloric acid and the solids salt and sugar. They clip leads from the hand generator to wires immersed in each substance.

In this activity, PVC pipe, plastic water bottles and vinyl tubing are used to make a simple working toilet model. The model shows the role of a siphon in the flushing of a toilet.

The Ancient Egyptians used a naturally-occurring salt from the banks of the Nile River, called natron, to mummify their dead.

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 chemistry activity, learners use spaghetti to explore density and chemical reactions.

In this activity, learners build a model of a self-sustaining habitat (growing grass and beans from seeds).

In this chemistry demonstration, learners will discover that phenolphthalein is an acid/base indicator. One learner will read a poem about four witches making a potion.

In this activity, learners explore how engineers develop pipeline systems to transport oil, water, gas, and other materials over very long distances.

In this physics activity, learners will explore buoyancy.

In this activity, learners model, on a human-sized board game, how changes in water temperature may affect fish distributions and, ultimately, fisheries.

In this activity, learners cut out and assemble wheels to explore how variations in fish body structures (mouth shape/position/teeth, body shape, tail shape, and coloration patterns) allow fish to sur

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

In this activity, learners measure and calculate the amount of cubic feet various containers contain. Next, learners investigate cubic feet per second (cps), by carrying jugs in one second.

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.
