Students discover the harm and benefits of microbes. In this biology lesson, students explore water, nitrogen and carbon cycles. They investigate the factors affecting bacteria growth.

In this earth science worksheet, students answer fifty multiple choice questions and thirty-three short answer questions in preparation for the earth science final exam.

In this soil formation worksheet, students will review examples of chemical weathering and biological weathering. Students will also review the different soil layers and how they are created. This worksheet has 6 matching, 5 multiple...

Eighth graders explore variables that influence the rate of erosion due to the 4 major agents. They work as a group and practice conducting experiments according to the scientific method. Students comprehend that communicating ideas...

Fourth graders examine how weather events cause weathering of the Earth's surface and how freezing water creates cracks and broken rocks over time. They observe what happens when a jar full of water is frozen overnight, and record their...

Second graders explore erosion and find the factors effecting erosion of hillsides.   In this erosion activity, 2nd graders experiment by creating a hillside and simulating rain.  Students discuss and record their results...

Fifth graders study early explorers. In this World history lesson, 5th graders draw an outline of a map labeling each part, build geographical features out of dough, and paint each of the land and water features.

Students explore erosion. Through multi-media and hands-on activities, students identify the effects of wave erosion and hurricanes on a barrier island. Students watch a video and create a cause and effect chart of their observations. ...

Modeling dough and paper cutouts in science class? Learn about how relative age dating concepts, like the Law of Superposition and cross-cutting relationships, can be used to describe the formation of sedimentary layers.

Middle schoolers discuss the characteristics of the biosphere, with a focus on the Tibetan Plateau. They participate in a question and answer period discussing biomes and climate patterns. They compare and contrast different ecosystems.

Can an area with no soil turn into a forest? Scholars learn about the process of ecological succession using an interesting presentation. It covers both primary and secondary succession in the building of new ecosystems.

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...

Fifth graders examine how sand and rock fragments in soil are products of erosion or the weathering of rocks. They listen to the book "Sand" by Ellen J. Prager and answer discussion questions. Next, they analyze sand samples and sort...

In this rock cycle worksheet, students use different colored crayons to represent different types of rocks. They follow step by step procedures to model the rock cycle with the crayons. Students draw the rock cycle, show weathering,...

Learners assess the damage natural forces have caused Maryland's geographic features. In this state geography and ecology activity, students work in a group to research ways in which weathering, erosion, and deposition have affected the...

Students build and erode a hillside. In this earth science instructional activity, students build a five inch hillside in a paint pan using sand, soil, and pebbles. They pour water over the hillside to monitor the erosion and...

Students experiment using soil and water. In this forest as a filter lesson, students identify the role of forest cover, vegetation, and foliage impacts erosion and evaporation. Students conduct a simple experiment, form a hypothesis,...

Students investigate different types of landforms. In this landforms lesson, students explore landforms by participating in a WebQuest. Students research the reasons behind landforms changing and create a picture using KidPix.

Learners examine the relationship between water retention and plant growth by conducting two experiments. They first compare the water retention qualities of clay, sand and loam soil types. Then they use the data from the first...

Fourth graders review how erosion can happen by wind, water, and gravity which they studied in previous lesson. They attempt to discover if all soils erode at the same rate. In small groups, 4th graders experiment with three different...

A 22-slide set provides pretty much everything you need to teach the rock cycle except the actual specimens. All of the slides contain graphics or photographs to help describe the process, and most even have links to educational videos....

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.

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.

Second graders discuss various ways in which landforms change over time. They, in groups, research and create a reference book about landform change including tsunamis, earthquakes, weathering, erosion and volcanic eruptions.
