Students view a video that presents the biogeochemical cycle of nitrogen. They compare types of soils and consider how different fertilizers affect soil composition.

Students examine the organic and inorganic components of soil. In this environmental science lesson, students identify the factors that influence soil formation. They collect soil samples, conduct tests, and analyze the results.

Students compare and contrast primary and secondary cavity nesters. In this life science instructional activity, students explore the different types of nests that birds make. They play a team game to apply what they learned.

Fifth graders examine and participate in the process of classifying rocks. In small groups, they sort the rocks into two categories and complete a Venn diagram. Next, they select three rocks, and complete a worksheet that is in the...

Fourth graders complete three activities. In this water supply lesson, 4th graders learn that water can exist in different forms and watch a demonstration of each form. Students explore the water cycle and make a water cycle using the...

Students investigate types of soil to test their water permeability. They collect soil samples, make predictions, conduct the experiment, and answer conclusion questions.

The road to a better understanding of engineering lies with bridges and tunnels. A set of four engaging activities teaches learners about engineering concepts related to construction projects. They perform an experiment to find the...

Explore the practice of oyster gardening. Because oysters play a vital role in marine ecosystems and their populations have declined, biologists are transplanting oyster seed to repopulate reefs. After learning about this practice,...

The student will identify the difference in the rate of plant growth in three soils that vary in organic matter.1. Obtain three to four flowerpots, different types of soil, a record chart, three to five beans for each pot, and water....

This PowerPoint provides a game show format with multiple choice questions about fresh and salt water. Topics include sources of water, water geography, uses of water, and the water cycle.

Students collect and examine different soil samples. They test for specific types of soil elements and the pH level. They answer questions about optimum growing conditions as well.

Third graders work together in groups to discover the importance of soils. Using a worksheet, they answer questions as they surf the internet. They observe three different types of soils and record their observations and use the internet...

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...

Students explore the physical properties of rocks. They explore the three different types of rocks and are able to compare and contrast their different properties. Students simulate the creation of sedimentary rock, they also...

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.

In this water worksheet, students are given the percent of distribution of water on earth. With the total amount of water equal to 1,000ml students determine the number of ml for each type of water on earth and color a beaker with the...

For 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,...

Students determine which types of garbage are biodegradable and which are nonbiodegradable. They practice measuring skills, hypothesizing, taking data, and writing a lab report. Students observe the relative biodegradability of metal,...

Fifth graders describe a wetland habitat and its components. They provide, in writing, at least one example of a wetland food chain, relate wetlands to ecological functions, and relate the importance of wetland functions to their own...

Learners study soil and how particle and pore size affect water movement.  In this soil lesson students complete a lab activity to investigate pore saturation and sponge like behavior. 

Young ecologists investigate some of the many ways that human activities adversely affect the environment. After identifying the main types of pollution (air, water, soil), 3rd graders fill in a Venn Diagram by pasting cut-out pictures...

Students explore how water moves through soil. They experiment with different soil types and record their findings.

AP environmental science or college-level ecology classes will glean a tremendous amount of information on nutrient cycles from this detailed PowerPoint. It covers nutrient requirements, biogeochemcial cycles, decomposition rates, and...

Second graders conduct a plant experiment.  For this basic needs of plants lesson, 2nd graders observe plants for two weeks. Students record data from their plants in journals.
