Students discuss the threats facing migratory species and track the seasonal journeys of wildlife in real space and in cyberspace. Once they have gathered information from several sources, they create a portfolio to share with others...

Students visit a local stream, pond, creek, or river and collect macroinvertebrates. They sort macroinvertebrates and identify each species using a dichotomous key. Students decide on trophic levels and construct a possible food web for...

Students study what worms need to survive in different environments. They study how worm composting improves soil and reduce waste. They discuss composting techniques and present a puppet show about a worm's life.

First graders describe what help seeds need to grow, including light, water, good soil, and warmth, observe and discuss what happens when seeds do not have help, and state similarities and differences among seed growth.

Students determine

Students observe water birds feeding at a local wetland, record what they see, and construct an appropriate menu for a "Waterfowl Cafe." They also play a "flocking" game.

Young scholars gain an understanding of necessary components required within a healthy, sustainable environment and ways human actions can impact that balance while discovering how to recognize and analyze explanations and models used in...

Ninth graders explore how electricity is created and distributed through alternative production methods. Students participate in hands-on activities, research, lecture based instruction, and CD ROM resources.

In this biology learning exercise, students answer questions.

Students analyze organic production systems. In this organic agriculture lesson plan, students examine key organic practices for both crop and livestock. This lesson plan includes 5 different activities, 4 critical thinking questions and...

Students explore organic and inorganic objects. In this environmental lesson students perform a composting experiment using flowers in different soils. Students record their observations.

Pupils review what they know about non-renewable energy, compare and contrast advantages and drawbacks of each type, such as cost of energy sources, feasibility, air pollution, water pollution, and other risks, and create table listing...

Seventh graders discover how an ecosystem works by creating one in class.  In this Earth science lesson, 7th graders study vocabulary terms associated with ecosystem and read environment handouts.  Students create an...

Students examine whether their actions are positively or negatively affecting organisms and their habitats. They choose an animal to study then create a multimedia presentation including charts and graphs of data logger information and...

Read 37 slides on energy flow and the nutrient cycle.

This website describes trophic levels, transfer of energy between trophic levels, pyramids of ecology, and nutrient cycles within the environment.

Nitrogen is essential to all living things. This article explains what the nitrogen cycle is and the five steps involved in it.

Human beings have an enormous impact on the natural environment, and ultimately on each other. The way we chose to house, clothe, shelter, and meet the needs for vital resources such as food, energy, and water, not only affect the...

In this lesson plan, students address the impact of unsustainable fishing practices.

An overload of nutrients, called eutrophication (Greek for "good-nutrition"), can be harmful to estuaries. This phenomenon is also referred to as "over-enrichment," or "nutrient pollution". Students will investigate the range of...

For this lesson, students will extend their knowledge of matter and energy cycles in an organism to engineering life cycle assessment of a product. Students will learn about product life cycle assessment and the flow of energy through...

Learn that the nitrogen cycle illustrates how nutrients cycle through a terrestrial ecosystem with the chapter in this free textbook. Explains how nitrogen plays an important role for life. See a diagram of the nitrogen cycle that shows...

Students learn about energy and nutrient flow in various biosphere climates and environments. They learn about herbivores, carnivores, omnivores, food chains and food webs, seeing the interdependence between producers, consumers and...

An advanced discussion of plant interactions and relationships. Energy flow, nutrient cycling and succession are discussed. Try the quiz to check your understanding.
