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 water activity, learners discover ways to move water across the water table.

In this activity, learners explore how engineering has developed various means to remove impurities from water.

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

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.

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

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).

The Sacred Cenote at Chichén Itzá is a sink hole, or well, containing groundwater. In this activity, learners create their own cenote using chalk, limestone, acids, and rain water.

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

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

Learners follow directions to construct a water-powered electrical generator using a turbine made from plastic spoons.

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

In this environmental science and data analysis activity, learners work in groups to track a Dead Zone (decreased dissolved oxygen content of a body of water) using water quality data from the Nutrien

In this activity, learners will create a magnifying glass called a waterscope, using water and household items, to examine various objects.

In this activity about dinosaurs and survival, learners use scrap materials to create a miniature dinosaur habitat that includes a food source, water source, and shelter.
