Learners work in pairs to create three simple types of bridges, a beam bridge, an arch bridge, and a suspension bridge. They will observe how the bridges work under load and discover why engineers...

In this physics activity, learners build their own rockets out of film canisters and construction paper. Learners discover how a chemical reaction (from a mix of water and Alka-Seltzer) creates gas...

Learners conduct four simple experiments to demonstrate the effects of air pressure. They use Bernoulli's Principle, that moving air exerts less pressure, to manipulate air pressure and see...

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. Learners use this table to simulate...

In this geology activity learners build a "squeeze box," which allows them to compress layers of sediment. This is a great way to investigate folding and faulting in the Earth. The...

In this activity, learners explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered. Learners conduct an experiment using a plastic syringe and...

In this physics activity, learners will investigate the strength of egg shells. They will attempt to stack books on top of inverted half egg shells to see how many they can hold, and the results...

In this design challenge activity, learners build a tower that can support a tennis ball at least 18 inches off the ground while withstanding the wind from a fan. Learners will build a sturdy frame...
