We are grateful that on Friday, one of our student’s parents came to talk to the school about germs. She brought with her a model of a cold germ (magnification 1 million+) and discussed how germs live on and in our bodies. 
Germs also spread when we touch each other. This was simulated with gold glitter. (Apologies if some glitter came into your home–but if you find some, please talk about it!)
But, it’s not all bad, because we also talked about how soap washes away germs!
