In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

"Molecules in Motion" explores how materials behave and change in a vacuum.

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

In this outdoor activity, learners search for lichen, a combination of a fungus and an alga living together. Lichen grow where most other plants cannot, on rocks, the trunks of trees, logs and sand.

In this outdoor, ocean-side activity, learners investigate the distribution of organisms in the upper region of the intertidal zone.

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.

In this outdoor activity, learners make their own organic-rich soil. Depending on where this activity is done, learners will probably discover that their local soil is low in organic matter.
