This is a lesson about water I include during my cells unit. We discuss how 2/3 of the human body is water and how important water is to maintaining homeostasis etc. After my water introduction which usually includes notes, video and/or textbook research I have students complete a watercolor painting.
Students will use pencil to add information about water to their paper and then I teach the students the "wet on wet method" of watercolor painting and then have students share a watercolor set at their table groups.
Lesson includes student directions as well as a set of teacher directions that discusses background, materials, how to teach and tips etc.
