This fun video explains how to make a batch of oobleck (or slime) and why this special substance is known as a "non-Newtonian" fluid. Watch as Mr.

In this quick activity, learners take a balance challenge to measure their average balance time. As they collect data, they investigate how practice and repetition improve their balance time.

In this activity, learners heat ice and water of the same temperature to get a hands-on look at phase changes. This is an easy and inexpensive way to introduce states of matter and thermodynamics.

In this activity, learners explore water pressure by conducting an experiment with a garden hose. Learners build a testing apparatus and create PVC nozzles with different sized holes.

In this activity, learners conduct an experiment by heating an aluminum can filled with water to investigate air pressure.

In this activity, learners make three different "seed" types and determine which design flies the farthest.

In this activity, learners discover how their heart rate changes in different situations.

In this activity, learners conduct a controlled experiment to examine how many Mentos are needed to make the tallest possible soda geyser.

In this activity, learners conduct a controlled experiment to examine which brand of soda makes the best (highest) soda geyser.

In this activity, learners create a straw oboe to explore sound and pitch.

In this activity, learners compare the ancient Egyptian system of measurement, which was based on body lengths, to the customary and metric systems used today.
