The K2 class worked on a collaborative project using droppers and watercolors.
We spread out a white paper table cloth and watched as everyone added primary colors and saw how they would change when they mixed. When we had no more white to fill we called it a day and put it aside to dry.
It inspired me to cut it into a fish shape and have the students make it into the "Rainbow Fish", shiny scales and all. It's on display in the most fitting place, the library.
