In this activity, learners investigate the different salinity levels of oceans, rivers and estuaries.

In this activity, learners use a pneumatic trough (see related activity) to generate and collect pure oxygen.

In this activity, learners explore how nanotechnology is being used to create new types of protective fabrics.

In this chemistry meets cooking activity, learners make carbonated, vanilla ice cream using dry ice and denatured ethanol, which are both inexpensive and accessible.

In this activity, learners try to float ink on the surface of water to create a pattern and then capture it with absorbent paper.

This interactive demonstration reintroduces learners to three states of matter (solid, liquid, gas), and introduces them to a fourth state of matter, plasma.

"Sublimation Bubbles" allows learners to explore how some solid materials, such as dry ice, can phase change directly from their solid to gaseous form.

In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

In this activity, learners explore rocketry and the principals of space flight.

In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.
