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.

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.

Many people get water from a source deep underground, called groundwater.

This creative lesson plan provides a visual way for learners to gain knowledge about the finite amount of fresh water on Earth and encourages the discussion of the various ways to conserve this resour

An estuary is a body of water that is created when freshwater from rivers and streams flows into the saltwater of an ocean.

In this ecology activity (page 8 of the PDF), learners explore how to filter contaminated water using a variety of materials.

Learners see convection currents in action in this highly visual demonstration. Sealed bags of colored hot or cold water are immersed in tanks of water.

Glare from the sun and ripples from the wind can make it hard to see what's below the surface of a body of water.

By building a simple watershed with paper and markers and then using a spray bottle to simulate precipitation, learners will understand how pollution accumulates in our water sources, especially from

In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.

This activity (located on page 3 of the PDF under GPS: Alligator Habitat Activity) is a full inquiry investigation into organisms and the health of their ecosystems.

This is an activity about turbidity, or the amount of sediment suspended in water.

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

In this environmental science activity (page 3 of the PDF), leaners will identify and explain the causes of erosion.

In this activity, learners use gumdrops and toothpicks to model the composition and molecular structure of three greenhouse gases: carbon dioxide (CO2), water vapor (H2O) and methane (CH4).

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

In this demonstration, learners observe vinegar and baking soda reacting to form carbon dioxide (CO2) gas.

Learners create a model of a wetland to observe how it absorbs and filters water from the environment.

Learners discover that their breath contains carbon dioxide, one of the pollutants found in car exhaust.
