Using an idea I’d found a while back, I froze some water into a big block of ice for the boys to paint it with watercolors. Love Bug had no interest, but Sweet Pea was really into it.
When he was starting to lose interest in that and spending more time trying to pick up the block of ice, we turned it into a sensory activity and felt the ice and talked about how it felt and what it looked like.
We added a little water and saw how the look of it started to change. Then we added some salt for some science fun. By this point, all the paint had been washed away, though!
