For this lesson, my kindergarten students drew a cat and flowers in oil pastel and then painted over it with black water color.
I like watercolor paintings to be bright and cheery so I take out the black and brown paint. I have a lot of black watercolor paint because I take it our of our paint trays.
This lesson allowed us to use up some of those black paint trays. The hardest part is getting kindergarten students to color hard enough that the water color resists the paints.
