Georgia Science Grade 8Unit 6:
Waves, Sound, and LightLight showIntroduction: Light is a form of electromagnetic energy and has wavelengths that are visible to the human eye. Although we perceive sunlight as colorless, it actually contains all the colors of the spectrum. Task: Work with a partner to learn how light works and how we see color. Find out where natural light shows occur on Earth. Visit the web sites on light experiments and select one for you and your partner to conduct. Demonstrate the experiment for the class and explain the principle at work. Time: 1 class period for research and supply gathering, additional class time for experimentation and demonstrations Possible Resources: Light and How it Works http://science.howstuffworks.com/light.htm http://www.learner.org/teacherslab/science/light/ http://www.physics4kids.com/files/light_intro.html http://library.thinkquest.org/13405/intro/what.html http://www.opticalres.com/optics_for_kids/kidoptx_p1.html Earth's Light Shows http://www7.nationalgeographic.com/ngm/data/2001/11/01/html/ft_20011101.3.html http://science.nasa.gov/NEWHOME/headlines/essd23sep98_1.htm Experiment with Light http://wow.osu.edu/experiments/light/lightlist.html http://www.exploratorium.edu/snacks/spectra.html http://library.thinkquest.org/C005705/English/Light/lexperiments.htm |
