Objective: Identify how prevalent the use of solar energy is in your community. Science Skills: Observation Life Skills: Wise Use of Resources
Preparation Activities: Locate buildings and structures in your area that are collecting solar energy.
Help youth identify solar panels on buildings, light posts and other generators. Travel throughout your community and see how many homes and businesses you can find that have some solar panels installed.Use a GPS receiver or dot stickers and a road map to mark everywhere you find evidence of active solar collection.
You can also point out “passive solar” designs, which are buildings that were designed to make use of natural sunlight but which aren’t using active energy collectors. Some buildings use a combination of active and passive solar designs.
Title: Finding Ourselves on the Electromagnetic Spectrum
Objective: Experiment with the light spectrum Science Skills: Observe,Use Tools Life Skills: Communication, Disease Prevention
Preparation Activities: Print out “Fun Facts about Light” Gather experiment items or borrow from the Extension Office.
A lamp with a full spectrum light bulb, and LED light, an incandescent light, sunlight
Crayons or colored pencils, paper
Borrow a Solar Scientist Explorer Kit:
prism, magnifying glass, thermometer
Share “Fun Facts about Light” (see Explore More)
Have the youth position a prism under various light sources. (You will probably discover only sunlight makes a strong enough spectrum of color, so don’t do this activity in the cloudy season.)You can start by trying to make a prism with a variety of different light sources: an LED light, a halogen light, a flashlight, a full spectrum bulb. Tell them it will make a rainbow when the right kind of light shines through it and let them search for sources. They can also try concentrating light using a magnifying glass.
When they finally discover the rainbow effect, each youth can color the spectrum on a sheet of paper while a partner holds the prism steady.
White light is actually not white, it is a combination of all colors. By bending the light through a prism the invisible waves of color are stretched apart. Light travels to us through waves. Our sense organs (our eyes, our ears, our sense of touch) are just sophisticated organs for sensing electromagnetic waves. What other kinds of invisible energy waves move on the same spectrum as visible light?
Asking the Right Questions: What do you see when you use a prism? Why didn’t some of our light sources make rainbows? What makes a rainbow?What color is light? What is light? What is ultra-violet light and how does it affect us?
