The U.S. produced enough wind energy in 2015 to power all of the homes in Alaska, California, Delaware, the District of Columbia, Hawaii, Idaho, Maine, Montana, Nebraska, New Hampshire, North Dakota, Rhode Island, South Dakota, and...

All types of energy are presented here, with neat pictures and labels to illustrate the technology typically used. Ways of harnessing the energy most efficiently are discussed, and good examples provide starters for further research....

People have been using solar energy for many generations to dry crops, heat homes, and for light. This presentation explains how now it is possible to capture the solar energy and store it for future use, details how and where...

Wow! Colorful and simple, these 160 slides introduce the various forms of energy, along with a relevant image. Some of the images are animations, which help beginning physical scientists to visualize the flow of electrons or energy! This...

A single slide introduces each of the following renewable energy sources: hydroelectric, wind, geothermal, solar, tidal, and biomass. This provides a succinct overview that you can use as a visual aid when you first introduce alternative...

Consider biomass as an alternative energy source with this PowerPoint. Environmental science pupils discover the potential of converting gases produced by landfills into useful energy. They compare and contrast environmental and economic...

Earth's atmosphere is full of different energies, from thermal to wind to electromagnetic radiation. Through the presentation, class members discover these energies and how they determine weather patterns.

It's hot today, but is that the weather or the climate? This colorful presentation isolates both concepts to allow for better understanding by covering the positioning of the planet, making comparisons of land versus water, and looking...

The title is a little deceiving since only one of 17 slides is dedicated to the function of leaves, while the rest is dedicated to the structure. Both internal and external structure is taught with accompanying diagrams. If you are going...

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

A collection of photographs highlighting alternative energy sources from fields of wind farms to towers of solar panels.

Observe various severe weather phenomena in this image gallery from WGBH. Weather is the combination of factors -- temperature, wind, snow or rain, and sunlight and clouds -- that happen in a specific place at a specific time. Sometimes...
