Do great gardeners really have green thumbs—or just really great soil? Environmental scholars discover what makes Earth's soil and soil quality so important through research and experimentation. Learners also develop an understanding of...

Fourth graders investigate erosion. In this Science lesson, 4th graders explore the role of weathering and plant growth related to erosion. Students define the components of soil. Students explore the history of the Dust Bowl.

Fourth graders study 4 types of weather processes: wind, running water, plant growth, and freezing water. They explain how the processes of weathering and erosion change and move materials that become soil. They draw diagrams...

Fourth graders explore the agents of erosion. They observe rocks that are rough and unweathered and record observations. They investigate rocks rubbed with sandpaper and ones that are not and the effects that the sandpaper has on the...

Fourth graders investigate the impacts of erosion. In this Science lesson, 4th graders determine connections between plants and soil erosion. Students examine the historical implications of erosion.

Fourth graders study physical and chemical weathering. They explain how the processes of weathering and erosion change and move materials that become soil. They create a K-W-L chart to show what they know and list what else they would...

Students explain the causes of erosion, describe the effects of erosion, and devise a method of preventing erosion. They model the before-and-after-effects of erosion.

Water is essential for life—and understanding the importance of clean drinking water is essential in understanding sustainability! Show your environmental science class the basics of water testing and treatment through a week-long...

Students plan an ecotour of the Australian rainforest. They prepare fact sheets about animals, create a mural, prepare a advertising brochure and a guided tour of the rainforest.

Seventh graders discuss why hunter-gatherers might have favored certain areas in which to live. In pairs, they research specific regions to examine in depth. Students present their eco-region vegetation findings (in this case Central...

Students explore the Earth and its ability to support life. They discuss the geosphere and the water cycle and complete the Water Wonders activity. After completing the activity, they respond in their journals and reflect upon the...

Young scholars participate in a Web Quest activity in which they identify common exotic invasive plant species of the Southern Appalachian Region. After identifying the top 10 exotic invasive species, they choose one to research in depth.
