What about looking at something alive? This was the first use of a 
microscope. You could go to a local pond and collect pond scum (full 
of interesting living things) or perhaps you have an aquarium that 
has algae in it or order some protozoans from Carolina or another 
biological supply company (paramecium or amoeba last long in 
cultures). You can show lots of life easily. Visitors  find them 
fascinating (the Wentscope is easy to use for this purpose) and you 
can make all kinds or references (eg algae and the rise of 
multicellular life in part due to oxygen production many years ago).

I'd be glad to help just contact me off line.

Cheers,

Martin
