Sometimes conservationists use specific plants to prevent erosion or fight invasive species. A 50-slide presentation covers both nonvascular and vascular plants. It discusses the plants, their stages and life cycles, reproduction, uses,...

Eighth graders describe the steps in the water cycle. They discuss factors that affect runoff and explain the differences between stalactites and stalagmites. They discover the importance of ground water.

Students investigate a frog's life cycle. In this tadpole lesson, students observe tadpoles in an aquarium and record results. Students fill in a KWL chart as an assessment.

Students define igneous, metamorphic, and sedimentary, and use rock identification books to identify igneous, metamorphic, and sedimentary rocks. Students then discuss which rocks early man would have found useful for tool creation.

Students use stream trays covered in different types of rocks or soil to investigate infiltrates and runoff. In this water pollution lesson, students work in groups with stream trays that have different substrates. They write a paragraph...

Students explore water. In this water cycle lesson, students conduct a scientific investigation that requires build a terrarium models of the earth. Students record their observations of the changes regarding water in the terrarium.

Five pages take biologists on a generalized survey of the origin of life. Queries are made regarding theories of how life developed, ancient Earth conditions, and the ever-changing field of taxonomy. The experiments of different...

Students illustrate how water is stored and the water cycle. They discover how underground water can become contaminated.

In this environmental science worksheet, students complete a crossword puzzle with 26 questions about human impact on the environment.

Students trace a molecule of water through the water cycle including each of its three loops. They describe why evapotranspiration demands the largest portion of total precipitation falling on a forested watershed.

Students explore the Earth's movements by completing worksheets. In this plate tectonics lesson, students define such natural disasters as volcanoes, earthquakes, tsunamis and mudslides and discuss their connections to plate tectonics....

Seventh graders take an outdoor observation walk around the campus and take soil samples. Working in groups , they conduct experiments with rocks and soil that demonstrate the effects of different types of erosion.

Students are introduced to the processes of evaporation and condensation as they observe physical changes in water. They observe how matter changes from a solid to a liquid state. Students are explained that steam is water in its gaseous...

High schoolers examine the concept of radioactive dating. In this radioactive dating lesson, students investigate how to determine the ages of fossils and rocks as they learn about half-life radioactive decay.

Students compare the properties of rocks. They identify objects made of rocky materials such as walls, sidewalks, etc. Students describe and group rocks based on their characteristics.

Students play rock-paper-scissors and create a play to demonstrate the butterfly life cycle. In this butterfly life cycle lesson plan, students also plant a butterfly garden with plants that attract butterflies.

Fourth graders, in groups, use books to identify types of rocks. They examine the rocks and complete rock evidence charts. Students compose definitions for each rock type and determine uses for igneous rocks by early mankind.

Whether you wrap it or fill it, you're using geometric concepts. Classmates use an interactive approach to learn how to find volume and surface area of cylinders and prisms in the second lesson in a five-part series. The online lesson...

Explore vocabulary related to three-dimensional shapes. An instructional website describes the characteristics of different geometric solids. Learners can use an interactive component to view nets, faces, vertices, and edges of common...
