Meeting of the Waters Creek November 7, 2007 Questions: 1. In order to estimate the velocity of the water, we used two large rocks as markers of approximately a meter. Then we dropped a leaf at the first rock and timed how long it took for it to reach the second rock. It traveled the meter in about 4.5 seconds, equal to a velocity of .22 m/s. It is important to note that this measurement was taken on the inside of the stream, the outside of the stream would have been a little faster. 2. Sediments: a. The largest grain’s size was around 3 mm., however it was an outlier. For the most part, the handful of sediments ranged from .5 mm. to 2 mm. The majority of particles were 1 mm., while 2 mm. grains came in a close second. An important factor to realize is that it was raining, so the grains clumped together easily and it was difficult to differentiate the sizes accurately. b. The largest rock we encountered was about 17.78 centimeters by 27.94 centimeters. c. The large rocks appear to be igneous and sedimentary. There is a great mix of rocks from all different periods in time. We came across basalt (igneous) and sandstone
