In this outdoor water activity, learners explore how to change the direction of water flow. Learners make puddles in dirt or use existing puddles and sticks to make water flow.

Learners make a refrigerator that works without electricity. The pot-in-pot refrigerator works by evaporation: a layer of sand is placed between two terra cotta pots and thoroughly soaked with water.

In this design challenge activity, learners build a boat that can hold 25 pennies (or 15 one inch metal washers) for at least ten seconds before sinking.

In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.

This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.

In this activity, learners discover how solar energy can be used to heat water.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

April showers bring May flowers, but what do coastal storms bring?

In this hands-on activity, learners use the steps of the design process to create a hook to rescue a "space capsule" from the water.

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

Learners build models of sinkholes to gain an intuitive knowledge of their physical aspects.

In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

In this activity, learners explore clouds and how they form.

Learners will understand the relationship between climate change and sea-level rise.

In this activity with several mini experiments, learners explore the chemistry that helps scientists learn about the environment and how they can help save it.

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.
