Here is a writing prompt that we did last week. The prompt is: What's really at the end of the rainbow?
Some of the answers to this question were really interesting...I was only able to post a handful on the bulletin board because I didn't want people to think odd thoughts about my students.
When making the rainbow we started talking about the color spectrum because they thought they could have free choice when coloring the rainbow. We will continue this discussion and I will let the students experiment with prisms to create a rainbow. The clouds on this project are cotton balls.
