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

This activity (located on page 8 of the PDF) introduces learners to the concept of Non-point Source Pollution--what happens when rain washes garbage and other pollutants into rivers and lakes.

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 online activity, learners discover how random variation influences biological evolution.

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 will create their very own constellation.

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.

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

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

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

In this activity, learners model atmospheric convection currents using food coloring, water, and clear cups. Activity includes step-by-step instructions, STEM connections, and more.
