For SCIENCE

We did an oil-and-water experiment today. The children wanted to do something a bit structured, so we got the balance, found a couple of identical cups and weighed them, and poured equal volumes of oil and water into each one. Then we weighed them. Then we poured them together and mixed them up. And put a lid on and turned it over. And dyed it with food colouring. And got very excited about drawing pictures about it. And...

It was all such a success that we did the thing I read on Patch of Puddles about bowls of hot, body temperature, and cold water. They are still doing that, as far as I know; I have fled the splash zone myself.
