This series of chemistry stations is designed to accompany the PBS documentary about African-American chemist "Percy Julian: Forgotten Genius." Each of the six stations features either a chemical or p

In this indoor or outdoor water activity, learners pour water from small cups to large cups and containers. In doing so, they discover water takes the shape of its container.

Professor John Endler traveled to Trinidad in the 1970s to study wild guppies. In this activity, learners take part in an online simulation of Endler's work.

In this design challenge activity, learners build a car that can travel at least four feet using rubber band power and use the design process to debug problems.

In this physics activity, challenge learners to make a rubber band-powered spool racer. Demonstrate principles of motion as well as potential and kinetic energy.

In this activity, learners play a guessing game to explore classification.

In this activity, learners construct paper airplanes that twist and turn.

In this engineering activity, challenge learners to build a tower out of 10 sheets of newspaper and 3 feet of masking tape, which can hold a golf ball balancing at the top.

In this design challenge activity, learners use tubes of newspaper to make a table that’s at least eight inches tall and strong enough to hold a heavy book!

This guide features three related ramp explorations in which learners investigate the following science concepts: when placed on a ramp, some objects roll, others slide, and others stay put; the shape
