In this activity, learners make models representing bones on Earth and bones that have been in space. They discover what happens to bones without proper exercise and nutrition.

Ocean acidification is a problem that humans will have to deal with as we release more and more carbon dioxide into the atmosphere.

In this activity, learners explore why the sky is blue. Learners model the scattering of light by the atmosphere, which creates the blue sky and red sunset, using a flashlight and clear glue sticks.

Learners build a can that automatically returns after being rolled away. The can has a rubber band inside that stores energy as the can rolls one direction.

In this activity, learners explore clouds and how they form.

In this activity, learners follow a recipe to make hollandaise sauce. Learners discover how cooks use egg yolks to blend oil and water together into a smooth mix.

In this activity, learners touch supercooled water drops with an ice crystal and trigger the water drops to freeze instantly.

In this optics activity, learners make a simple telescope using two lenses and a cardboard tube. Learners construct the telescope and then calculate its magnification.

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 activity about electricity and magnetism, learners examine what happens when a magnet exerts a force on a current-carrying wire.

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

In this chemistry activity, learners use yeast and hydrogen peroxide to generate a gas (oxygen) and test some of its properties.

In this neuroscience activity (4th activity on the page), learners make their own set of Von Frey hairs to test detection thresholds.

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

The demonstration/experiment provides quick proof that air has mass.

In this activity (4th activity on the page), learners test to see if saliva is necessary for food to have taste.

In this activity (2nd activity on the page), learners explore how the nose is responsible for part of the flavor we taste in food.

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

In this chemistry activity, learners explore density by using four solids and 6 liquids to create colorful, layered rows.
