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 discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.

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.

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 quick activity, learners observe how salinity and temperature affect the density of water, to better understand the Great Ocean Conveyor.

In this activity, learners explore in what ways the shape of the land and the pull of gravity influence how water moves over Earth.

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 online activity, learners see simulations of how processes shape the Earth, and see estimates of how long these processes take.

In this demonstration, learners observe vinegar and baking soda reacting to form carbon dioxide (CO2) gas.

Ocean acidification is a problem that humans will have to deal with as we release more and more carbon dioxide into the atmosphere.

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

In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

“Exploring Earth: Rising Sea” is a hands-on activity demonstrating ways to use topographical mapping techniques to track changes in sea level. The activity is connected to current NASA research.

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

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

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

“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 explore clouds and how they form.

Learners blow into balloons and collect their breath--carbon dioxide gas (CO2). They then blow the CO2 from the balloon into a solution of acid-base indicator.
