Subject: What topics/labs would you include if limited to 5 or 10 days?

If you were designing a microbiology unit (specifically bacteria) for a 
high school class-what would you BE SURE to include? I would have access 
to bunsen burners, TSA Plates(petri), gram stain, microscopes, and 
students would already understand sterile technique. I will not have 
access to an incubator. So, what would you MAKE SURE to cover? what would 
need to be covered so they would be ready for a college micro or beginning 
bio class? I have a few ideas myself-such as the "ubiquity of 
microorganisms" where students swab several areas around the lab and then 
swab that onto a TSA plate and let sit overnite, so they can get an 
accurate picture of how bacteria are really everywhere. Hope this is 
enough info and i really appreciate your help, thanks-nate.
