I came home from work the other day to find my 6yo making a mess in the garden. As you can see from the photo, she had put all her pavement chalks in a bowl of water and was mixing them up! When I asked what she was doing, she looked up at me and said "It's an experiment. I want to see what happens."
I was intrigued to find out more about the experiment. So I asked her to tell me about it.
"When I put the chalks in the water, they sizzle. And the sizzling comes out of little holes made by the water" she said. "It makes this elephant colour. And the chalks get smaller. Maybe if I keep mixing, they'll disappear forever. I'll let you know..."
I was genuinely impressed by her approach (despite the fact that she ruined a perfectly good set of chalks). She had wondered what would happen if she put them in water and then designed a method of finding out. She was also making careful observations and recording her findings!
