First test to children

I made a test with three different age children. 

Firstly, I introduce some basic germs knowledge to them. And then, I show my E-book and tell the story to them. And I ask some simple question when I telling the story. Such as, who is the main character? What’s mean of reproduce? What’s germ? What’s mold? Why Lacto want to find a friends? 

I got some reflects from children when I do this experiment.
