A very good Kindergarten lesson plan about germs, is to take glitter and put in your hand (palm up, and enough that the kids can see, but you aren’t on the ground for an hour cleaning it up, lol) but then pretend to sneeze into the palm of your hand (exhale like a sneeze so a force of air blows across your palm). The glitter will disperse like germs. (not completely, but enough for Kinder kids to understand). The kinder kids will see the glitter blow into the air and land on desks, chairs, counters, toys, floor, etc. Then we’d talk about germs. They could see how far germs traveled from a sneeze or a cough.
I forgot to add that perhaps Congress and the Obama Administration need to see the kinder lesson.
