Learners conduct four simple experiments to demonstrate the effects of air pressure.

In this activity, learners create a CloudSpotter wheel and record the different types of clouds they observe twice daily over several days.

In this activity, learners explore properties of water and watch evaporation happen by "painting" with water in the sun.

In this activity, learners build a miniature wind tunnel to measure force. Learners construct the model out of Lexan plastic, a fan, and a precise digital scale.

In this activity related to magnetism and electricity, learners create a magnetic field that's stronger than the Earth's magnetic field.

In this activity, learners model estuaries, artificially enriching both fresh and salt water samples with different amounts of nutrients and observing the growth of algae over several weeks.

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

In this activity (page 26 of the PDF), learners make observations, formulate hypotheses and design a controlled experiment, based on the reaction of carbon dioxide with calcium hydroxide.

In this outdoor water activity, learners explore evaporation by painting with water and tracing puddles. Learners will discover that wet things become dry as the water evaporates.

In this activity, learners take core samples of candy bars with a straw and carefully observe & excavate their sample, modeled after what the NASA Perseverance rover will do on Mars.

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 use plastic water bottles, wood, and water to build an inexpensive and portable tool to demonstrate one atmosphere of pressure at sea level.

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 try to blow up a balloon hanging inside of an empty bottle.

In this activity, learners create a "mini sky" in a glass of water in a dark room.

In this activity, learners make a model of a pollution spill that occurred at Bangs Lake in Mississippi and measure water quality parameters in their model.

In this activity, learners conduct a simple experiment to see how electrically charged things like plastic attract electrically neutral things like water.

In this water activity, learners explore how water drops behave on different surfaces.

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 use basic measurements of the Earth and pieces of rock and iron to estimate the mass of the Earth.
