This is an activity about robotics programming. Learners will discover how precise programmers have to be as they instruct a friend to make a peanut butter and jelly sandwich.

In this activity, learners will explore the chemistry of cooking. They will learn about--and observe--the Maillard Reaction as they make their own browned butter.

Learners combine hydrogen peroxide with three different forms of potato: raw chunks, ground chunks, and boiled chunks.

In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.

In this hands-on activity, learners make the world's simplest Cartesian diver, using only a plastic bottle, some water, and a condiment packet.

This simple and engaging astronomy activity explains nuclear fusion and how radiation is generated by stars, using marshmallows as a model.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

In this activity, learners explore how eating unhealthy food can damage a heart and arteries.

In this activity, learners create a necklace of wheat germ DNA. Learners add alcohol to wheat germ so that the DNA clumps together.

In this activity, learners use water, oil, and food coloring to observe a chemical reaction that creates a shower of colors inside of a glass.

Learners add drops of alginate solution to a solution of calcium chloride. The alginate does not mix with the calcium chloride, but forms soft gel beads.
