Tessa: An area of the stream was chosen to determine temperature, stream width and stream depth and stream velocity. The temperature of the stream was tested by placing a thermometer in a normal area of the stream meaning it wasn't placed in a sunny area. To find the normal range of temperature for the stream, we placed the thermometer in a shaded are of the stream. Then to find the air temperature, we held the top of the thermometer and stood in a shaded area. A rope was tied across the stream and we measured from where the water met the land on each side of the stream and got 2.65 meters shown in the results above. To identify the stream depth, there were 4 points given on our rope that was hung across the string. We measured from the point to the stream and found the given results above. To test the stream velocity, we started at one spot of the stream and put a tennis ball down and timed how long it took it to reach the second spot we had marked on the stream. We put four tennis balls down individually and at different times and timed them.

Colder water has more dissolved oxygen than heated water shade makes colder water the better the water the colder it can get man shaped the landscape for hundreds of years sometimes harmful sometimes helpful Forest floor is often spongy due to dead organic matter called duff best regulator of water quantity is the forest floor forest floor works as a natural fertilizer some natural resources we get from this watershed are oil coal and lumber.
