I was dining alone with 3½ tear old Abel the other day, when he put a spoon into his glass of water. (His mother need not know about the 50 year old toy truck that helped feed him by ferrying grapes across the table.)
‘It makes it bigger’, Abel announced of his spoon in the water, so taken with this that he did not notice the photograph being taken,
‘Like your magnifying glass’, I suggested. He considered this for a moment. ‘My magnifying glass is missing.’ I feel sure he knows exactly where it is. He seems to think that things like to hide. Under the piano is a good spot.
But note the budding scientist: don’t tell him he’s wrong, when he is simply not in possession of enough facts and enough vocabulary to say more clearly what is happening. Let’s see if he can find that magnifying glass!
