In this quick activity, learners explore how blubber protects animals from the cold by making a "blubber mitt." Using cooking shortening, two zip-top sandwich bags, and duct tape, learners simulate bl

In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.

In this activity and/or demonstration, learners illustrate visually and physically that air has weight. Learners balance two equally-inflated balloons hanging from string on a yard stick.

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.

Learners discover that their breath contains carbon dioxide, one of the pollutants found in car exhaust.

In this activity (on page 2 of the PDF), learners explore surface tension by adding pennies to cups which are "full" of plain water or soapy water.

This is an online simulation of how sound changes due to environment. How does place--like a cave, a pier, or a forest--affect certain sounds?

In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.

"What's in the Water" lets participants use tools to solve the mystery- what chemicals and compounds are in a sample of water?

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