Students view continuous spectra from incandescent and fluorescent lights and line spectra of selected elements. Students relate energy to frequency of light seen in the spectra. The presence of only certain lines in atomic spectra is related to Bohr's model of the atom. In a second experiment, students determine electron energies in the hydrogen atom. Less

In this activity, learners explore phosphorescence and how certain materials can absorb and store energy from a light source. Learners use critical thinking skills to hypothesize which type of light -- incandescent, ultraviolet, infrared or fluorescent -- will produce the brightest glow from a glow-in-the-dark star. Learners perform an experiment using cameras to observe the intensity of the resulting glow from each type of light source. Less

In this activity, learners actually feel the difference in energy required to light two different types of light bulbs: incandescent light and LEDs. Learners will use a generator (hand crank) to provide the power and observe that the bulbs are equally bright. They will be surprised to learn that incandescent bulbs require more energy. This is a hands-on activity that works best if learners experience cranking the generator themselves, and works well at a learning station or center. This activity can be incorporated into a lesson on energy efficiency and/or used during winter holidays since it uses holiday lights. Less

Students are introduced to the correct technical vocabulary for lighting, which is different than layperson's terms. They learn about lamp (light bulb) technology and how to identify the various types of lighting in their spaces. They are also introduced to lighting controls as a means for saving energy- reducing costs, human energy consumption, and greenhouse gas emissions on the environment. Using an accompanying worksheet, students embark on a guided audit in which they survey the lighting in their classroom and identify the potential savings from using controls. Less

In this activity (posted on March 12, 2011), learners follow the steps to construct a spectroscope, a tool used to analyze light and color. First, learners use relatively simple materials to construct the device. Then, learners look through their spectroscopes at a variety of different light sources including incandescents, LEDs, compact fluorescents, sun light, etc. and compare what they observe. This resource includes a few examples of how certain chemicals form different colors of light. Less

In this activity, learners explore the relative efficiency of different bulbs, specifically incandescent vs. fluorescent. Learners will observe that energy "wasted" from an incandescent bulb can be used to run a solar cell toy. Then, they will experiment to find out what happens to the solar toy when they block infrared light by placing Thermashield and colored gels in between the toy and lamp. Less
