Learners investigate the properties of rocks. In this geology lesson, students draw their profile and discuss what a soil profile would look like. Additionally, learners demonstrate how to make soil by rubbing two pieces of sandstone...

Third graders examine what makes soil by creating a Venn Diagram.  In this Earth environment lesson, 3rd graders identify the different components that soil is made from. Students bring soil from their homes to examine and create a...

Fourth graders graph the percentages of the materials that make up the Earth and complete computations based on their results.  For this topsoil lesson, 4th graders diagram the different layers of Earth's composition.

Students work together to perform experiments on different types of soil. They record the soil's pH level, color and texture. They develop hypothesis' on what they believe they will discover before beginning the experiment.

Fourth graders explore different levels of soil. In this soil instructional activity, 4th graders investigate the amount water that can be absorbed by topsoil, subsoil, and bedrock.

As an example of nature's water filtering system, young ecologists conduct an experiment in the lab. They construct a funnel out of a plastic bottle, fill it with specified layers of materials that simulate layers of soil, then run muddy...

With almost half of Americans relying on groundwater supplies, it is more important than ever to protect aquifers from possible contaminants. Working in small groups, young environmentalists explore this problem as they create an aquifer...

Students observe the melting of ice. In this phase change lesson, students observe ice as it melts. They discuss the process and create a Venn diagram comparing water and ice.

Students explore genes and the way we age. They assemble a worm collection device called a Baermann Funnel. Students collect Caenorhabditis elegans or other active nematodes from local soil samples. They observe the appearance and...

Students make a model aquifer to study the uniqueness of Cape Cod's ground-water system. Using the model., they determine how easily contamination spreads in the aquifer system by completing and recording three activities. Using the...

Students set up a stream table, observe erosion, and record data on where various sizes of sediments settle. They draw conclusions as to what kind of sedimentary rock form in what locations.

Students recognize differences in the size, shape, texture, and color of different rocks. In this rocks lesson plan, students also learn and repeat back how a volcano erupts and make one out of a toilet paper tube.
