In this quick and easy activity and/or demonstration, learners use two empty soda cans to illustrate Bernoulli's principle. Learners lay the two cans parallel to each other on a level surface...

In this interactive and informative group activity, learners use packages of M&M's to illustrate the difference between weather and climate. Learner work in groups to sort and average the...

In this simple activity, learners explore ocean waves. To find out if water moves forward toward the shore, learners create waves in a simulated ocean (small aquarium tank of water). Learners...

Learners develop an understanding of air pressure in two different activities. They model the magnitude of air pressure as gravitational force per unit area, and they use cookie wafers to model how...

In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater. This...

Learners compare the properties and solubilities of Styrofoam (TM), ecofoam packing peanuts, and popcorn. First, the solubility of each substance is tested in water. A drop of iodine is added to...

Learners use a candle to investigate the products of combustion. When a glass rod is held over a lit candle, the candle flame deposits carbon on the rod. Then the candle and a drop of pH indicator...

In this activity, learners investigate how increased carbon dioxide (CO2) emissions from the burning of fossil fuels is changing the acidity (pH) of the ocean and affecting coral reefs and other...
