One of the coolest things that we do in STRETCH is teach students different ways to reuse and re-purpose things that may easily be thrown in the trash. With a simple rectangle box (or even a paper towel tube) and an used CD, we were able to make a spectroscope with my 1st and 2nd grade students. A spectroscope is an instrument that splits light into different wavelengths which we see as "colors." At the top of our device, we made a little slit for the sunlight to hit the shiny surface of the CD and on the side of the device, we made a cut out for the viewing hole. The result is rainbow-tastic! Check it out below. :)
