Eu Fai spotted a wierd looking plant with a Fly's wings sticking out of it in the Usborne children's encyclopedia (Yes, my kids go through encyclopedias for FUN!).
So I told him it was a Venus flytrap and asked if he wanted to see how it eats insects on Youtube.
He watched the plant devour a frog, a slug and various insects.
Then he exclaimed " That plant is alive! It moves and eats! It is like an animal!"
Oh My! What a teachable moment.
