We planted vegetables with the Grade Fours last year for this challenge, and in a day, the monkeys had ripped all of them out the pots. This year, I wanted to try something totally different and interesting.
I chose Aquaponics, because it is an interesting and topical way to do waterwise farming, and it also teaches learners about the symbiotic relationships that exist between plants, animals and bacteria.
The fish make compost, the bacteria turn it into plant food, and the plants help clean the water for the fish.

We did mini desktop projects for our Water Festival, but we did explain how this can be expanded to full-scale commercial farming. Aquaponics is a more sustainable way of producing vegetables, as it uses less water, and the crop often grows quicker than a soil-based crop. Add to this edible fish, and one has an excellent source of food and income.
We made a slightly larger system in the Media Centre on the windowsill which will be safe from our monkey friends. This is done on the floating raft idea, and I introduced this to the Water Explorer learners with a power point before I made the actual project. We have just started, with two Tilapia fish, a thyme plant and some tiny butter lettuce seedlings which were germinated on damp paper towel in a plastic bag.
Next time around, I want to choose some learners to germinate the seeds and plant them on.
