I actually found a science experiment on the subject (in addition to numerous hand washing songs that, frankly, I wouldn’t recommend).

Has anyone used vegetable oil — or something called GloGerm — to show kids all the hot water, soap and scrubbing that it takes to free their hands of germs?

Sounds like a timely science lesson to me…

Here’s a story my colleague Kim Wetzel wrote on the flu virus and a document outlining the procedures schools should follow (from the California Department of Education). The state health department wants schools with even one case of it to close.
