In this activity, learners discuss the different salinities of oceans, rivers and estuaries.

In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.

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 demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle.

In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

Millions of organisms can live in and around a body of water.

In this activity, learners will make their own prism and use a glass of water to separate sunlight into different colors.

Did you know that a Slinky makes a handy model of earthquake waves?

In this activity, learners create models of erosion and floods and learn to recognize both in their environment.

In this activity, learners will build a model of a nebula using cotton balls and colored water. Astronomers photograph nebulas and add colors to provide information about the nebula's composition.

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, groups cut out and sort cards showing items recovered from a crash landing on the Moon. The 12 items range from food and water to rope and matches to a self-inflating life raft.

In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

In this activity, learners eat a snack and make a model of the plumbing system of a volcano.

In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.

In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.

This fun and simple hands-on astronomy activity lets learners explore model planets (that they or an educator will create), using methods NASA scientists use to explore our Solar System.

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.

Learners build a solar oven from a cardboard pizza box, aluminum foil and plastic. Learners can use their oven to cook S'mores or other food in the sun.
