Light

Two sequential parts to this lesson introduce your class to the electromagnetic spectrum, the ability to absorb radiant energy, and the pigments in leaves that are responsible for collecting sunlight to be used in the photosynthetic...

Warm up to the idea of solar energy. A instructional activity includes three activities that challenge scholars to apply knowledge in new ways. First, they learn to run an alarm clock without a battery by using solar energy. Next, they...

Explore the behavior of light with different materials. Collaborative groups determine whether certain materials absorb, reflect, diffract, or transmit light waves. They then measure the angle of incidence and angle of reflection.

Combine art and science with this fabulous lesson plan where your class will create solar-powered artwork! They will create a cyanotype, using photo-sensitive paper, sun, and water. A list of necessary materials is provided.

Introduce your earth science enthusiasts to the earth's energy budget. Teach them using an informative set of slides that include illuminating lecturer's notes, relevant vocabulary, embedded animations, colorful satellite maps, and a...

Does the angle of a solar panel change the output? Emerging engineers find out! Demonstrate for your class how they can angle a straw to match the angle of light rays coming from a source. Then turn them loose to experiment with the...

This well-designed presentation covers many important aspects of the science behind light. In it, pupils view slides that have a lot of the important vocabulary associated with science, slides of famous scientists who made important...

Students discover the properties of light (radiant) energy from the sun by experimenting with solar collectors, cookers, and calculators. After a lecture/demo, students create their own solar collectors and test their efficiency.

One day's worth of sunlight can supply everyone on Earth with electricity for a year! Why, then, do we find ourselves in an energy crisis? Shine a light on solar energy with a short lesson and video. As part of a larger energy unit from...

Demonstrate how the spherical shape of the Earth contributes to unequal heating of its surface and results in varying climates at different latitudes. This would be an illuminating addition to your meteorology lessons, especially when...
