River Lab



Experiments

Elevation of River Bed

We were able to measure the elevation of a section of the Ocmulgee River bed by using two poles with a string attaching them. When they are both place in the ground as far apart as they can be with the string straight, we then use the markings on the poles to assess the change in elevation between them. The class did this from one end of the river to the other. The results are plotted on the graph above

Flow rate of the channels

The flow rate of the channel was measured by taking a floating object (empty water bottle) and letting it flow down stream with the current. The time it took to pass a certain marker was recorded with a stop watch. We compared the flow rate data with different sections of the river.

Theorize preference of clams

There were numerous empty clam shells scattered throughout the river bed. We collected samples of them in different areas of the river and found much more clams in the hard soil where the river was not moving as fast.

Favorite Place on Google Earth


This is an image of the Thermopylae Pass, where the Battle of Thermopylae was fought in 480 B.C. Though the ocean shore line has recede over the last 2500 years. Where the street is now is where the ocean shore would have been when Leonidas was alive. The building off the road to the top left of the picture is actually a moment to the legendary Spartans.
