In this three-part activity, learners use paper to explore Bernoulli's Principle — fast-moving air has lower pressure than non-moving air. First, learners observe what happens when they hold a...

Ocean acidification is a big issue due to the amount of carbon dioxide humans release. CO2 in the atmosphere is absorbed into the ocean thus changing its acidity. The more acidic the ocean becomes,...

In this activity, learners (at least three) work together to explore the effects of atmospheric pressure. A learner (at least 100 lbs) will step inside an extra large trash bag, while another...

In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment. In this modern, low cost version, a pair of learners try to pull apart two suction cups (dent...

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays. Learners use "detectors" (UV beads) at five different stations,...

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 test exhaled breath for carbon dioxide and learn how to use an indicator as a simple way to measure pH. Learners also explore what happens when an acid (lemon) is mixed...

This demonstration/activity helps learners understand why higher elevations are not always warm simply because "hot air rises." Learners use a tire pump to increase the pressure and...
