In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.

In this activity, learners make a barometer, an instrument to measure change in air pressure.

The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.

Make a one-string "guitar" by stringing a cup with some fishing line. You amplify the plucking of the string by placing a piezo contact microphone and mini battery powered amplifier inside the cup.

Through doing these hands-on activities, learners explore the environmental consequences associated with fossil fuel usage.

The goal of this activity is to build a miniature bobsled that is either the fastest or the slowest. Learners use recycled materials to design, build, and test their bobsled on a bobsled track.

In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.
