In this chemistry challenge, learners identify which plants have the enzyme "catalase" that breaks hydrogen peroxide into water and oxygen.

In this activity/demo, learners discover how liquid nitrogen cools a creamy mixture at such a rapid rate that it precipitates super fine grained (nano) ice cream.

In this activity, learners will turn cream and salt into butter—using marbles. Learners will explore how shaking up fat globules help them create homemade butter.

In this activity, learners make instant ice cream without using a freezer.

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

In this activity, learners will conduct an experiment to discover methods of reventing foot mold growth on food.

In this fascinating and fun experiment, learners use chemistry to identify a mystery powder and to solve a "crime," a process similar to that used by real forensic scientists.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

In this activity, learners test what happens when they put baking power on different frozen liquids.

Learners observe a tank of water containing cans of diet and regular sodas. The diet sodas float and the regular sodas sink. All the cans contain the same amount of liquid and the same amount of air.

Some animals can swallow food whole, but humans have to chew. In this activity, learners will investigate what saliva does chemically to food before we even swallow.

In this activity, learners test different food items by timing how long it takes each liquid to slide from the top of a ramp to the bottom.

In this experiment, learners test multiple food items to see if they are an acid or base using an indicator solution created with red cabbage.

Learners mix liquid water with solid cornstarch. They investigate the slime produced, which has properties of both a solid and a liquid.

In this physics activity, learners experiment with the attractive and repulsive power of magnets.
