In this weather activity which requires adult supervision, learners will get a chance to make a cloud right here on Earth!

In this activity, learners explore the different salinities of various sources of water by taste-testing.

In this activity, learners investigate how wind can create surface currents and how waves move. Learners also discover how wind can affect oil spills.

In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.

In this activity, learners use cheap, thin plastic garbage bags to quickly build a solar hot air balloon. In doing so, learners will explore why hot air rises.

Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

In this activity, learners discover if carbon dioxide has an effect on temperature.

In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

In this activity, learners (at least three) work together to explore the effects of atmospheric pressure.

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

“Exploring Earth: Investigating Clouds” is a hands-on activity in which visitors create a cloud in a bottle and explore it with laser light.

In this activity (on page 2), learners create a submarine using a plastic cup. This is a fun way to learn about buoyancy and density.

On an airplane trip, learners have an opportunity to investigate the properties of air pressure at different altitudes.

In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.

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

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

In this activity, learners explore how air warms when it condenses water vapor or makes clouds.
