The many sources of energy production in the United States are described in this overview. Included are traditional sources, renewable sources, and new energy production technologies.

In this lesson, students look at profiles of energy production for different regions of the United States. They examine the conversion efficiency and the carbon dioxide emissions of each type of energy, and then the environmental impact...

This lesson addresses the following questions: What is the efficiency with which energy is converted from trophic level to trophic level? What are the differences between assimilation efficiency, net production efficiency, and ecological...

Small groups to research products made from petroleum other than fuels. The challenge is to find such products "hiding in plain sight."

This video segment adapted from NOVA/FRONTLINE looks at American energy consumption and the resulting production of greenhouse gases. [4:59]

Students work with ice cubes and different colored paper to develop observations in order to prove energy can be transferred from one object to another. Resources include videos of the lesson in action, examples of student work, and...

This simulation can be used as a virtual lab for photosynthesis, cellular respiration, and primary productivity.

Hydroelectric power has been a major source of energy production in the United States. More recently, other alternative energy sources have taken some of its market share. Hydroelectricity has both advantages and disadvantages, briefly...

Easy-to-understand information on mining and transporting coal, producing it, uses of coal, and coal and the environment.

One major advantage with the use of renewable energy is that as it is renewable it is therefore sustainable and so will never run out. Renewable energy facilities generally require less maintenance than traditional generators. Their fuel...

Article discusses importance of Photosynthesis in terms of food, energy, and environment. Relates process to human needs.

It's hard to believe that the same water that you use every day to quench your thirst, cook with, bathe in, swim in, and wash your clothes and dishes, is capable of another trick-it can make electricity. Electricity can be generated...

In 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 the...

Industrial engineers improve processes by eliminating any waste of time, money, energy, or other resources. They need to understand how every part can affect the entire process and figure out how to balance each part to design the most...

An interactive graph that predicts how many years until more than two dozen natural resources (e.g., chromium, oil, tin, coal, etc.) are depleted, based on current production rates or production that grows each year. Use the slider at...

A suite of lessons focusing on the process of upwelling. Inquiry-based exploration of seasonal upwelling includes marine food webs, food production in the ocean, wind-driven ocean currents, and seasonal changes in biotic and abiotic...

The status of wind energy production in the United States is described, with the advantages and disadvantages of this alternative energy source.

In this activity, you will be able to observe the oxygen production in leaves by doing a floating leaf disk experiment. You can also find out how quickly plants produce oxygen, and what variables affect photosynthesis.

This activity aims to explore the production process and its advancing technologies to better extract petroleum for products and energy use. What happens to production as the amount of oil in the ground decreases?

Compared to incandescent lamps, fluorescent lamps last longer, require less energy and produce less heat, advantages resulting from the different way in which they generate light.

An interactive activity for you to find out how much your lifestyle depends on mining. Students select household items and learn facts about their chemical nature, properties and uses, their origins in the Earth, mining, and production.

Coal is still widely used in energy production but is responsible for a third of the carbon dioxide emissions in the United States. New technologies, described here, are being developed to reduce or eliminate these emissions.

The US Energy Administration gives an overview of Afghanistan with an emphasis on energy production. Includes map of Afghanistan and statistical information.

Young scholars are presented with information that will allow them to recognize that yeasts are unicellular organisms that are useful to humans. In fact, their usefulness is derived from the contrast between the way yeast cells and human...
