Next lab, lab 9 we will be studying the unit "the world in a drop of water". We will be using three sources of water, one from the fish tank, two from the water fall, and three water from the Represa Guarapiranga. A large reservoir. I think we will see different living organisms in the water. For example if it is dirty water we might find bacteria. We might find the source of oxygen in the water which fish use to breath through. I have the feeling that this will be a very interesting topic to study and that we will go deeper than just exploring cells. I can't wait!
