Methods To begin the experiment materials were gathered: a net, waterproof boots, a poker, a pan, a tennis ball, and a yard stick. Four locations were chosen to take samples from, two stagnant waters and two flowing waters. In each area three random spots were chosen using a random number generator. Then the net was held in the water by one person, and another person who is wearing the waterproof boots kicks water into the net for thirty seconds. The net is then taken out of the water, and its contents are dumped into a pan. The contents of that pan are then sifted through, to look for any arthropods. The amount of arthropods would then be recorded, along with if there were any of the same kind. In each of the places that samples were taken from, the velocity of the water should also be recorded. That is done by placing a meter stick alongside the stream, and then putting a tennis ball at the top of the meter stick, above where the water is flowing down. Then the amount of seconds it takes the tennis ball to move along the meter stick is recorded.media type="file" key="video3.mp4" width="300" height="300"media type="file" key="video4.mp4" width="300" height="300"media type="file" key="video2.mp4" width="300" height="300"media type="file" key="video5.mp4" width="300" height="300"media type="file" key="video1.mp4"
