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

In this activity, learners create their own weather forecast map.

In this data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.

In this activity, learners will listen to as many radio stations as possible to discover that AM radio signals can travel many hundreds of miles at night.

In this activity, learners observe the hydrologic cycle in action as water evaporates and condenses to form rain right before their eyes.

In this activity, learners create their own icons for a forecast-at-a-glance poster for their classroom/learning space.

In this activity about color, learners get to explore the process of chromatography. Right before their eyes, they can watch ordinary green and black ink turn into a literal rainbow of colors.

This activity (on page 3 of the PDF under GPS: Cactus Activity) is a full inquiry investigation into how some desert birds keep their cool.

In this thought-provoking activity, learners plan a hypothetical project to build and operate wind turbines in their community.

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 act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.

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 explore why frost forms. They create their own frost using a solution of ice water and salt in a glass.

Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.

In this activity about global climate change, learners will conduct an experiment and collect data to compare the amount of carbon dioxide (CO2) in four different sources of gases.

In this environmental science activity (page 4 of the PDF), learners use vinegar and chalk to observe the effect of acid rain on various building materials and plant life.

This activity (on page 2 of the PDF under SciGirls Activity: Lift Off) is a full inquiry investigation into the engineering challenges of sending scientific sensors into space.

In this activity, learners estimate how much water they think can be found in various locations on the Earth in all its states (solid, liquid, and gas) to discover the different water ratios in the Ea

Learners test two jars of ice water, one covered and one open, for changes in temperature. After placing the jars in the sun, learners discover that the covered jar cools down more slowly.
