Right now, the Institute for Systems Biology is working on a crowdfunding campaign to help teachers like you obtain funding for building a classroom aquaponics system. We also recommend Donors Choose, a crowdfunding website specifically for education projects. Just create an account, follow the instructions and create a project to be funded. In this case, that would be your aquaponics system. If you are using Donors Choose, nearly all of the materials listed can be purchased from Donors Choose approved vendors.
