observations 1

I went out to the pond on September 19th at 4 pm  and used a digital thermometer and placed it in the water and sand till the numbers stopped. It was about 70ish outside with 0.01inches of precipitation. I did not notice anything really out of the ordinary. I did see a fish though. I only felt the water and sand. I could not hear anything except the neighbors.

Controlled Variables: spot in water, spot in sand, depth, thermometer, day time.
Procedure: Go to the place you want to research and pick a spot of sand and water and measure that place's temp each week. and record the difference
