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

“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, 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 observe the water cycle in action! Water vapor in a tumbler condenses on chilled aluminum foil — producing the liquid form of water familiar to us as rain and dew.

From the Weather Watchers featured theme on the CYBERCHASE website. Learners will conduct experiments to discover how air temperature and humidity work together to make condensation, dew, and fog.

In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

Learners see convection currents in action in this highly visual demonstration. Sealed bags of colored hot or cold water are immersed in tanks of water.

In this demonstration, learners can observe a number of small convection cells generated from a mixture of aluminum powder and silicon oil on a hot plate.

In this activity related to climate change and data analysis, learners examine temperature and precipitation data to determine if climate variations are due to El Niño.

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

In this weather-related activity, learners make a portable cloud in a bottle.

Learners cover a bottle with a balloon. When they immerse the bottle in warm water, the balloon inflates. When they immerse the bottle in a bowl of ice, the balloon deflates.

In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.

In this activity, learners use a toaster to generate wind and compare the appliance's heat source to Jupiter's own hot interior. Learners discover that convection drives wind on Jupiter and on Earth.

In this activity, learners create a biosphere in a baggie.

Learners develop an understanding of air pressure in two different activities.

In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

In this activity, learners thread colored beads onto string. Each beach represent a process of the water cycle.
