The author Eric Carle was the inspiration of the next project.
Eric Carle is an amazing children's author and illustrator. 

This project took two parts. The first part was to take white construction paper and apply drops of paint on it. The goal was to mix primary colors to get different tints and hues throughout the paper. To apply the paint, we used a brush and pulled the paint across the paper while it blended with the other paint. After the paper was dry, we traced our design onto the painted paper of our choice. Then we cut our our design and glued it into place. 

I like this project but the entire time I was trying to think of away this project could be geared toward younger students. A way to accomplish this would be to give every student a white piece of paper. Then give each table a tray of white, black, and blue paint. Then have the student choose how light or dark they would like the blue to be. I would instruct the to cover the entire piece of paper. Then once the paper is dry, have the students think of things that are blue (examples: clouds, water, clothes, etc). I would have cut out cardboard piece of these examples. The student could trace them onto the blue paper and cut it out. This way they are working on finding different hues and tints of a certain color but also matching that color to something they know already.
