Learners experiment with a 2-liter plastic bottle containing water and four “divers." The divers consist of open, transparent containers with the opening points downward.

In this activity, learners examine raindrop bottles (prepared ahead of time) to observe in slow motion the behavior of falling droplets and explore concepts such as drag and terminal velocity.

In this activity, learners discover that two pendulums suspended from a common support will swing back and forth in intriguing patterns, if the support allows the motion of one pendulum to influence t

In this activity about light and perception, learners create pictures in thin air.

Learners explore the Bernoulli effect by building an airfoil (airplane wing) and making it fly.
