The Boy Child came home with Science homework.
Music to The Brainy One's ears.
"Write up the experiment (maximum of 6 lines) and draw a diagram."
There was no real clue in The Boy Child's Science exercise book as to what the experiment might have been on.
Twenty minutes of Q and A later and we had a rough idea.
With The Boy Child dictating of sorts, The Brainy One wrote up the method in rough and I drew (ha!) the diagram.
We both enjoyed it.
The Boy Child not so much.
