Investigate the interaction of liquids of different densities and experiment with wave patterns with this hands-on activity.

In this quick activity, learners drink Avogadro's number worth of molecules - 6.02x10^23 molecules!

In this matching activity (3rd activity on the page), learners use their sense of smell to match pairs of opaque containers filled with various smelly items like orange peel, roses, or moth balls.

In this activity, learners model hot spot island formation, orientation and progression with condiments.

In this activity, young learners (2 years and up) explore tree structure and biology. Tree products are explored by painitng with fruit.

In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

In this a hands-on activity, learners explore how to put ice cream in an oven without it melting. Ideas in this activity include insulation and cooking.

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

In this math activity, learners trace their hands and estimate the number of beans that can fit into their hand tracings. Then, learners glue the beans to the tracing to test out their estimations.

In this activity, learners sublimate dry ice and then taste the carbon dioxide gas.

In this activity (4th activity on the page), learners use their sense of smell to rate and arrange containers filled with different dilutions of a scent (like cologne or fruit juice) in order from wea

This hands-on activity lets participant explore chemical reactions as they create a soda explosion with lots of bubbles. The bubbles in soda are made of carbon dioxide gas.

In this activity, learners mix up a bubbly brew and examine density. Learners explore how they can make different materials fall and rise in water using oil, water, and salt.

In this quick activity, learners break the tension that happens when water develops a "skin." Learners use water, pepper and some soap to discover the wonders of surface tension—the force that attract

This activity helps learners learn about math through a real-world scenario. Three friends are baking cookies for their school’s bake sale.

In this chemistry activity, learners use spaghetti to explore density and chemical reactions.

In this activity (7th activity on the page), learners use their sense of hearing to find a "sound match." Learners shake containers filled with items like dry seeds, sand, beans, etc.

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

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

In this activity, learners add food coloring to hot and cold water in order to see how fluids at different temperatures move around in convection currents.
