Maybe try using it to grow plants emersed, to compare/contrast emersed/submersed leaf growth. I'm sure it can hold 4" of water with some peat and vermiculite on the bottom. Imagine the crypts and swords you could grow in that setup! Might even be able to keep some tree frogs or lizards in the setup while you're at it.
