Hydroponics in our Aquarium

Miss Coffey here from Caroline Elementary School... We're currently on spring break, but that doesn't stop me from working or taking care of our trout!!! Yesterday I went into school for awhile to get some stuff done. As I fed the excited fish, I saw that our hydroponics experiment was working! The grass floating on the top of the tank is growing!
