For this second of three lessons on power plants, future engineers find out how we generate electricity and how coal-powered plants operate. They work in small groups to make electromagnet generators to light LED bulbs. A set of...

Double, double toil and trouble, fire burn and cauldron bubble! Find out what drives a turbine to generate electricity and whether or not it has an impact on the environment. A discussion and lecture is divided by a hands-on activity in...

The principles of pollution control on a molecular level are summarised here. The reasoning and study behind the principles are described, and your class will undestand how some techniques are developed to be more efficient.

A food web consists of complex food chains and the more complex the web, the better likelihood of survival. Learners compare and contrast food webs and food chains and discuss concepts like the predator-prey and consumer-producer...

Ninth graders explain the purpose of MPA's. In this biology lesson, 9th graders identify MPA's in Southern California. They simulate coastal sampling using candy from two buckets. Students analyze their results and share it with the class.

Students explore the issue of climate change through participation in an interactive game show. They explore climate change issues in the news. Students write and discuss their own questions about climate change.

Students compare and contrast abiotic and biotic factors. They discuss how these factors effect ecosystems. They answer questions to complete the lesson.

Students explore the effect aerosols have upon he weather and climate. They observe NASA satellite images to explore and draw conclusions about aerosol transport. From studying the images, students track the path of aerosols. They...

Students compare the efficiency of producing food calories in different types of food then calculate how much land is required to supply their food for a year. They then graph the results.

Seventh graders investigate the concept of how an ecosystem is put together while conducting research using a variety of resources. They correctly differentiate between a herbivore and carnivore by placing them in the order of hierarchy...

Students recognize and identify major groups found in the Arctic benthos. They describe common feeding strategies used by benthic animals in the Arctic Ocean. They discuss relationships between

Students identify the three realms of the Arctic Ocean, and describe the relationships between these realms. They describe different species associations in a benthic community.

Students use NASA satellite data of optical depth as a tool to determine volcanic activity on Reunion Island during 2000-2001. They access the data and utilize Excel to create a graph that has optical depth as a function of time for the...

Several activities are included to teach and research the differences between renewable and non-renewable resources and various energy resources. Young scholars work with a quantitative, but simple model of energy resources to show how...

After learning about all the energy sources, students will be able to list and identify the economic and environmental advantages and disadvantages of them.

With an introduction to the ideas of energy, students discuss specific types of energy and the practical sources of energy. Hands-on activities help them identify types of energy in their surroundings and enhance their understanding of...

In this lab activity students generate their own biomass gases by heating wood pellets or wood splints in a test tube. They collect the resulting gases and use the gas to roast a marshmallow. Students also evaluate which biomass fuel is...

This detailed chemistry lesson from the U.S. Department of Energy focuses on transforming vegetable oil into biodiesel through a process of transesterification. The process described offers a good model for many chemical reaction...

This lesson will introduce energy pyramids, and show how energy moves from one trophic level to the next. It is 2 of 4 in the series titled "Energy Pyramids."

For this activity, students learn about the pros and cons of co-firing woody biomass fuels with coal to produce electricity.

Learn about the many different energy resources available from our Earth. Find out the pros and cons of each type: both renewable and nonrenewable.

This lesson will introduce energy pyramids, and show how energy moves from one trophic level to the next. It is 1 of 4 in the series titled "Energy Pyramids."

Society is beginning to recognize the limited supply of fossil fuels. In this project, students will investigate alternative energy sources. Conservation of resources is discussed and while conservation is an important step, at some...

Read 37 slides on energy flow and the nutrient cycle.
