This was a great activity because it touched on science, math, colours, patience, colouring in the lines... and it was totally fun!
How To Do It:
1. Add a drop of food colouring to the water in each ice cube, before freezing. (Talia loved getting to add drops of food colouring by herself)
2. Make a paper with math equations for different colour combinations, leaving an empty spot for the answer. (We took this opportunity to talk about what the "+" and "=" signs mean)
3. The next day, fill glasses with ice cubes in different colour combinations & watch to see what colours they make when they melt! (This was fun but took a while, so we added leftover cubes to cups of water for more food colouring fun while we waited)
4. Let your child colour in the answers when it's all finished.
I got this idea from a blog, but I can't remember where now!
