For our lab we all went to the Ocmulgee river. For our first activity, my group scanned an area and sifted through the sand looking and counting the freshwater clams we would come across.
The next thing we did was measure the water elevation of the Ocmulgee river.
The last activity we did was to check the speed of the water current. To do this we had one person stand up current and another person about 100ft down current and time how long it would take a sponge ball to float to the opposite end. Our first try it took forty eight seconds and for our second try it took a minute and fifteen seconds.
