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 experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

In this activity, learners explore how salt water freezes in comparison to fresh water.

In this activity, learners make pykrete by freezing a mixture of water and a material like cotton wool, grass, hair, shredded paper, wood chips, or sawdust.

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

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.

“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 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 explore how air warms when it condenses water vapor or makes clouds.

In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper

In this activity, learners heat and cool carbonated water to find out whether temperature has an effect on how fast the dissolved gas leaves carbonated water.

In this activity, learners "draw" with frozen tempera paint. The ice cubes are prepared the day before by placing watered down tempera paint and popsicle sticks in ice cube trays.

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.

In this chemistry activity, learners observe a combustion reaction and deduce the components necessary for the reaction to occur.

What causes frost to form on the outside of a cold container? In this activity, learners discover that liquid water can change states and freeze to become ice.

In this chemistry activity, learners witness an exothermic reaction, while making their very own, completely usable sidewalk chalk. This is also an excellent activity for exploring color mixing.

In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials.

In this activity, learners explore density, convection, stratification, and, by inference, the melting of icebergs. Learners make hypotheses, test their hypotheses, and explain their observations.

In this experiment, learners float colored ice cubes in hot and cold water.

In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.
