In this activity, learners explore the forces at work in water. Learners experiment to find out what happens to pepper in water when they touch it with bar soap and liquid detergent.

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

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

In this activity, learners explore static electricity and electrical charges while experimenting with an inflated balloon, unflavored gelatin powder, and a wool sweater.

In this activity about olfaction (7th activity on the page), learners use natural ingredients to concoct their own perfume.

Perform this classic inertia demonstration to illustrate the transfer of potential energy to kinetic energy.

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 activity, learners compare frog eggs to chicken eggs to better understand why frog eggs need water. Learners compare a boiled chicken egg to "frog eggs" represented by boiled tapioca.

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 genetics activity, learners discover how to extract DNA from green split peas.

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

Learners place cut flowers in colored water and observe how the flowers change. The flowers absorb the water through the stem and leaves.

In this math activity, learners create their own units of measurement by making noodle rulers. Learners practice estimating and measuring objects using the noodle rulers .

In this engineering activity, learners investigate the differences between the strength of bridges made from flat and round building materials.

In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle.

In this chemistry activity, learners are asked to form a hypothesis about the behavior of milk as household detergents act upon it.

In this activity, learners discover what happens when they crush wintergreen-flavored candies in a very dark room.

In this geology activity (page 6 of the PDF), learners explore how carbonic acid can slowly dissolve limestone and form caves.

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.
