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 will make their own prism and use a glass of water to separate sunlight into different colors.

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.

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

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.

Learners blow into balloons and collect their breath--carbon dioxide gas (CO2). They then blow the CO2 from the balloon into a solution of acid-base indicator.

In this activity, learners use tonic water to detect ultraviolet (UV) light from the Sun and explore the concept of fluorescence.

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

In this demonstration, learners compare and contrast regular water ice to dry ice (frozen carbon dioxide). Both samples are placed in a solution of acid-base indicator.

In this quick activity, learners observe how wind creates ocean currents.

In this activity, learners make a 3-D model of magnetic fields by inserting a small, strong magnet into a sphere.

Some bugs can walk on the surface of a lake, stream, river, pond or ocean.

In this demonstration, learners observe the effects of density and pressure by attempting to make "balloon kebabs." Learners will try to insert a wooden skewer all the way through an inflated balloon

This simple hands-on activity demonstrates why the sky appears blue on a sunny day and red during sunrise and sunset.
