Today the 1st graders will look at light and texture. We will build the RGB LED project below. We will take a small square of Japanese art paper and wrap it around the powersource and RGB LED. The paper vaires in density quite a bit as do the lights. Each of the three R,G,B LED’s are placed at different points within the clear dome of the main LED so light diffusion is quite variable in one cycle. We will look at how similar these modules are to the kinds of photos we see of far away dust laden galaxies in the universe and ponder how diffusion is the same on earth as in space.
