Seas of Grass

The ocean may seem a world away, but you can actually find it in a science classroom! Learners in the lower grade levels explore the concepts of water pollution, apex predators, the worth of animals, and commercial fishing methods. High...

On April 22, 1970 over 20 million Americans participated in the first Earth Day. But why? The beginnings of what is now a world-wide event, celebrated in over 190 countries to support environmental awareness and protection, are the focus...

Compare heating and cooling rates of different land forms. A lab activity has groups collect data on the rate of heating and cooling of soil, grass, saltwater, fresh water, and sand. An analysis of the rates shows how the different land...

After challenging themselves to correctly choose the form of erosion and length of time required for a given landform to develop, earth science class members model mechanical and chemical weathering with various lab demonstrations over...

Learners construct a model of the hydrologic cycle, and observe that water is an element of a cycle in the natural environment. They explain how the hydrologic cycle works and why it is important, and compare the hydrologic cycle to...

Erosion is the leading cause of the loss of topsoil and sediment deposits in ditches, streams, rivers, lakes, and oceans. The ninth lesson in a 10-part series includes two different activities related to soil erosion. First, scholars...

How can organisms light up in water? Bioluminescence is light produced in a chemical reaction that can occur in an organism's body. First, learners determine what happens to light/color as you move into the deep ocean. In groups, they...

For this science worksheet, students read the article related to currents and complete the exercises that are multiple choice and short answer.

Students participate in hands-on activities dealing with what lives in the ocean. They also read literature about the oceans.

Eleventh graders practice the Quadrat Survey Technique to analyze the biodiversity of a local plant community. They compare its biodiversity with the documented changes in biodiversity of the tallgrass prairie over time.
