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.

In this activity, learners explore healthy choices related to the liquids they drink. The importance of water and milk as essential nutrients for a healthy body is the focus of the experience.

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 investigate the properties of the liquids in two bottles. One contains layers of oil and water, and one contains oil, water, and soap.

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.

In this activity, learners conduct a series of hands-on experiments that demonstrate how the working of plants' veins, known as capillary action, enables water to travel throughout the length of a pla

This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.

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 this activity, learners will make fish cutouts that propel through the water with the help of surface tension.

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.

In this physics activity, learners will explore the concept of buoyancy, especially as it relates to density.

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