In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean. The...

In this experiment, learners float colored ice cubes in hot and cold water. They compare the behavior of the melting ice cubes to understand how temperature is related to ocean currents and how...

In this experiment using sprigs of Elodea, learners will observe a natural process that removes carbon dioxide (CO2) from Earth's atmosphere. This process is a part of the carbon cycle and...

Albert Einstein proved that space bends around anything that has mass. This activity uses Jell-O's ability to bend around objects as a model for space bending around planets and stars. The...

Learners test their "light-smarts" by playing a game called "Light Quest!" The game board represents an atom and each player represents an electron that has been bumped into the...

Using simple, inexpensive items, learners build and test submarine models. They gain insight into the engineering that's required to make these machines ascend, descend, and hover safely in...
