      This seems like an interesting lesson idea. And I like that you are connecting the lesson to a book.

      I am unfamiliar with the book and wonder if it talks about the refraction of light or other related science concepts.

      Can you help me understand that?

        I just realized this looks like a 1st or 2nd grade lesson. This book I choose is more so about the colors of the rainbow, I think I'm going to swap it out for a more "sciency" approach that is more suitable for the 4th grade.
