AP Biology lab book, huh? Lab Twelve...
This is lab twelve in the AP Bio course. You can assume that the stream is a stream with a good current, so oxygen will get incoorperated with the water through turbulance. There is more turbulance in a stream than in a lake. This factor will result in higher concentrations of DO in a stream. Also, the overall temperature in a stream is lower because the sun cannot heat moving water as fast as it can heat non-mobile water.Both of these factors will result in a higher DO in the stream than in the lake.
