Students examine soil. In this earth science lesson, students define and describe weathering and erosion as it relates to soil. Students compare and contrast potting soil with forest soil and complete a science observation worksheet.

Students are able to describe earth processes (e.g., rusting, weathering, erosion) that have affected selected physical features in students, neighborhoods. They are able to identify various earth structures (e.g., mountains, faults,...

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.

Students study the changes in land formations caused by water erosion. They work in groups to build a model of a mountain composed of materials that will best withstand water erosion.

Fourth graders examine the effects of waves on coastal land. They discover how water's power can change the appearance of land formations.

First graders examine different types of rocks and minerals. They create models of the rocks and minerals they find interesting. They discuss and explain three ways in which the earth changes.

Young scholars build and experiment with a watershed to understand the effects of pollution. In this movement of water lesson, students work in groups creating rock formations and change the viscosity of the liquids falling down the...

Second graders conduct experiments with rocks to observe weathering. They read books, examine websites and watch a video to examine how rocks break down into soil.

Fourth graders observe the effects of water on the soil and record those effect by drawing sketches of water erosion and conservation practices.

Ninth graders take soil samples and perform tests on these samples.

Fifth graders brainstorm a list of ways the Earth's surface can change. As a class, they are introduced to the concepts of erosion and weathering and discover how wind and water cause changes to the surface of the Earth. To end the...

Students explain how sand dunes are formed, the different circumstances that effect the movement of or formation of sand dunes, and relate the information gathered to soil conservation. In this sand dunes lesson, students use pans of...

Students investigate the concept of caves by conducting an experiment. The lesson contains background information for the teacher. They collect data while making observations and write a review of the concept once the experiment is...

Students build a soil erosion model to study the importance of soil conservation. They investigate how land forms from both constructive and destructive forces.

Students observe, measure, and graph a model of slow down slope movement representing soil creep. This task assesses students' abilities to collect, record, and organize data, set up graph axes, plot data points, draw line graphs, apply...

Students discover soil characteristics and how it is formed on Earth and the Moon by examining local samples to a lunar simulant. They replicate the effects of wind erosion by scraping dry bread with sandpaper. Students use rocks and...

Fifth graders conduct experiments in simulated water pollution using a box of items to hold "pollutants"and an aquarium, representing a waterway. They observe how "rain" from a watering can poured into the box washes the pollutants into...
