In this demonstration, learners investigate mass, gravity, and acceleration by dropping a wooden bar with a balloon attached to its underside, a mass suspended from it by rubber bands, and a sharp-poi

In this physics activity, learners conduct two experiments to explore free-falling.

In this activity, learners make optical fibers out of strips of gelatin.

This activity explores the basic workings of a siphon, which is the core technology that makes toilets work.

In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.

This lesson focuses on molecular motion in gases. Learners compare the mass of a basketball when it is deflated and after it has been inflated.

In this chemistry demonstration, acid rain is simulated in a petri dish.

In this activity related to flight, learners conduct two simple tests to explore how lift works.
