In the first activity, students made a spectroscope to look at different light source, using a tissue paper roll, a CD  removed from its foil, black paper, a cutter, and glue. They learn that white light can be broken down into many different colours of the rainbow. In the second activity, students made a rainbow on a plate using different colored candies and water and noticed that the colors combined. They understood that white light can be made from all the colors of the rainbow.
