"I’m going to be a farmer. I know how to grow two types of crops. One crop is the normal kind. The other kind uses aquaponic systems. We have an aquaponic system in our classroom. It has a one ton tank with nine tilapia fish in it. It used to have ten fish but the biggest one died over Christmas break. His name was Frank. Anyway, the water in the tilapia tank gets filtered into another tank, where we are growing kale, hybrid spinach, and lettuce. Afterward, it gets funneled back into the tilapia tank and starts all over again. Everyday we have to measure nitrate, nitrite, ammonia, and one other thing that I forget the name so let’s not mention that one. Anyway, at the end of the year we are going to harvest everything that we grew. Then we’re going to make fish tacos."
