“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 discover the relationship between temperature and pressure in the lower atmospheres of Jupiter and Earth.

Learners color and cut out a spiral-shaped snake. When they hang their snake over a radiator, the snake spins.

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.

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

This warm weather activity introduces learners to the impact trees have on blocking the sun's heat and reducing temperature on the Earth's surface.

In this weather activity (page 4 of the PDF), learners will explore the water cycle through an interactive game.

In this activity, learners gain knowledge about how carbon moves through all four of the Earth’s major spheres (biosphere, hydrosphere, atmosphere, and lithosphere), and understand how humans influenc

Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.

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 water activity, learners discover ways to move water across the water table.

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

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

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 game, learners walk through an imaginary Carbon Cycle and explore the ways in which carbon is stored in reservoirs and the processes that transport the carbon atom from one location to another

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

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