In this activity, students create unique artwork using paper and finely grated chalk floating on top of water, and observe the effects of absorption and evaporation
Your students may have used chalk to make art before, although probably not in this way!
While creating their chalky masterpieces, students explore how the dry chalk and wet water interact with each other, and observe the effects of absorption and evaporation as the water on their artwork dries.
Questions about floating and sinking may also arise!
This is a great activity to do as a station, as it does require one pan or tray per student. You may want to set up a station with two or three pans and have the children take turns.
