In this activity, learners investigate how geometry plays a role in perspective.

In this lab activity, learners explore how to initiate a density current. Learners measure six flasks with different concentrations of salt and water (colored blue).

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

In this activity, learners will explore how the human brain interprets environmental stimuli.

In this experiment, learners construct an equilateral triangle using graph paper, a pencil, protractor and ruler. They also make a "laser triangle" using a laser pointer and front-silvered mirrors.

In this activity, learners work in teams to investigate the relationship between mass, acceleration, and force as described in Newton's second law of motion.

In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.
