In this activity, learners use gumdrops and toothpicks to model the composition and molecular structure of three greenhouse gases: carbon dioxide (CO2), water vapor (H2O) and methane (CH4).

In this physical sciences activity, learners explore how passive solar design increases energy efficiency.

In this activity, learners investigate wind by comparing the force of wind in different locations. Learners build wind-o-meters out of wooden sticks and strips of paper.

This activity helps learners understand how the angle of the Sun affects temperatures around the globe.

Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.

In this yummy activity about soil (page 9 of PDF), learners will create layers of soil using food. They will learn about the composition and role of each layer.

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 meteorological activity, learners get to build their very own anemometer (instrument for measuring wind speed) using a paper cup.

In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

In this activity, learners create a tornado in a bottle to observe a spiraling, funnel-shaped vortex. A simple connector device allows water to drain from a 2-liter bottle into a second bottle.

In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

In this activity, learners will turn an ordinary tray of sand into a desk-top garden for meditation.

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 activity, learners use simple items to construct a device for indicating air pressure changes.

In this weather activity (page 10 of the PDF), learners will demonstrate the changes in atmospheric pressure by constructing their own barometer.

In this activity (page 2 of PDF under GPS: Cave Swallows Activity), learners will model how caves are formed by placing one piece of chalk in a cup of vinegar and another piece in a cup of water, then

In this activity, learners create a model using metric measuring tapes and atmosphere composition data.

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

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.
