Energy in a Clean Environment

Working in groups of two, learners examine their own carbon footprints and energy consumption, then determine a plan to reduce their impacts on the environment. Although designed to be a final project for a chemistry class, the...

Emerging biochemists more fully understand the flow of energy in ecosystems as they explore the laws of thermodynamics and relate them to energy transfer in food chains. They also investigate heat loss from the human body and how...

Here is a wonderful series of lessons designed to introduce learners to the variety of renewable, clean energy sources used by people all over the world. Geothermal energy is the resource focused on. This particular sources of energy...

Is qualitative or quantitative research more convincing when it comes to climate change? In the eighth lesson during this 21-part series, scholars begin by performing a quantitative analysis of deforestation and urbanization. Then, they...

The series of videos on enthalpy change continues with this look at the Gibbs Free Energy System and Spontaneity. Most students have heard the term, "spontaneous reaction," and Sal explains exactly what a spontaneous reaction is and how...

Students identify and describe the different types of energy and how it is transferred.  In this energy lesson students complete several activities including how to calculate joules, adding up wattage, and create a presentation on...

Can Earth's oceans produce a steady supply of clean energy? Scholars explore the uses of tidal and thermal energy in the 11th installment of a 13-part series about ocean-based alternative energy sources. Learners examine the current...

If renewable energy sources are the best option, why aren't they used on a global scale? Junior environmentalists explore the benefits and problems associated with energy sources such as solar, wind, and biomass with a short video and...

A class discussion of the various combinations of energy resources used in our country opens this lesson. In cooperative groups, learners analyze data on conversion efficiency and carbon dioxide emissions for different combinations....

Another fantastic lesson on energy is presented by the American Coal Foundation. This one focuses on electricity; how it is produced, how it is delivered, and how it is used. Some excellent handouts are embedded in this fine plan which...
