The hypothesis is that the chemical levels will be lower in undeveloped Umptanum Creek rather than the more developed Wenas Creek.

You will take two .5 liter Depth and Width Integrated Samples from each creek, test sediment with a one liter Imhoff cone, and measure turbidity with a turbidimeter.

You will need a thermometer, two pairs of waders or hip boots, a liter of distilled water, a turbidimeter, a one liter Imhoff cone, and a nitrate test kit.

The results of the experiment showed that Wenas Creek had higher levels of turbidity and nitrates, but Umptanum Creek had more suspended sediment. This suggests that humans have an effect on the Wenas Creek but do not have much of an effect on the Umptanum Creek.

This science project is interesting because it looks at the effects of development on water quality in two creeks flowing from the same snowpack.

Variations of this experiment could include testing more than two tributaries, testing over a period of time, and testing at least once a month to see if certain chemicals being used during that time would affect the water quality more than other chemicals.

Hey there! Here are some awesome videos about this science project that we think you'll really like. They're not only super fun, but they'll also help you learn more about the science behind the project. So sit back, relax, and get ready to have some fun!!
