In this activity, learners build large-scale structures and cantilevers in a series of "building out" challenges with garden poles and tape.

In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.

In this activity, learners separate the components of Gatorade using a home-made affinity column.

In this physics activity, learners assemble and/or investigate a pendulum "snake." Several large steel hex-nuts are suspended on strings of successively increasing length to form a series of pendulums

In this activity on page 3 of the PDF, learners visualize the relative size and structural differences between microbes that have the potential to cause disease.

In this demonstration, learners watch as a device drops a ball into a cup without touching the ball or cup, even though the ball and cup are virtually side-by-side.

In this activity, learners cook amino acids and sugar to explore the range of aromas released.
