The AP Biology students read a passage from The Hot Zone. It depicted what happens to the human body when ravaged by a real bad virus like Marburg. Pretty sure some poetic license was used to describe some things but it was still fascinatingly gross.
The Chemistry students began the Gas Unit by attempting to discern whether or not certain items, like a pogo stick or a paper airplane, would work on a planet that is just like Earth but with no atmosphere. It turns out that air is pretty important.
