White Light Is Made Up of ...... ?
Learning would be more interesting with deeper thinking when students explore and discover the knowledge by experiments. In this lesson, the objective was to discover the colors that make up the white color. The 1st experiment was to see how light when passing from air to another medium scatters into 7 different colors. Then to emphasize this, students were supposed to prove this hypothesis in a reverse way. They cut a round disk and divided it into seven equal regions. Then they colored them with the rainbow colors and connected it to a source of energy. when the disk rotated, the colors mixed together and white color appears. Now my students can explain the natural phenomenon: the rainbow :)
