Science Fair Project: Biomass and Biogas

If you're ready to tackle something related to energy, power, and the environment but want to push the envelope a bit farther than the cool (but maybe not quite cutting-edge-enough-for-you and just a bit ubiquitous) Veggie-Powered Batteries, pull on your rubber gloves, grab a nose-plug (totally optional), and check out the ins and outs of biomass and biogas.

From Trash to Gas: Biomass Energy (grades 6-8) has you roll up your sleeves, fill up some soda bodies, and monitor differences in biogas production. In other words... what waste will inflate the balloon fastest?
