Before going to the stream students will need to understand depth, velocity and discharge. Students will at first be given minimal instruction and no materials. Students will be asked to try and decide the velocity and depth in order to calculate the discharge. Once they have an estimate with minimal instruction and materials students will meet back together to discuss the various ways they figured out the discharge. Each group will share their method with the class. Each group will then be given an orange, tape measure and a meter stick. They will again calculate the discharge of the stream. When done they will compare their first estimate with no materials with their second estimate in which materials were given to them.
