1st Visit

Field Notebook:

Visit 1:
I went and checked out my research area at around 7:00 pm. on September 29 when the time of day was 11 hours and 46 minutes long. It was around 65º and there was a little bit of a breeze. The sun was setting and it lit up the newly color changed leaves.  The river was flowing at a good rate, pulling at the water algae and the water spiders floating in the water. The sky was clear and changing colors. There were crow calls, seagull calls, and cricket calls. Cattails and trees swayed in the breeze while dragonflies and various insects buzzed around.  A Blue Heron flew off into the distance away from me. The land overall was perfectly beautiful.

The Movie: 

This movie shows the landscape of my experiment site. There is a creek that flows through a pipe into a larger river. Around the creek is a wood landscape.

The Question: 
How does the temperature of the water affect the levels of phosphate in the water?


The Hypothesis: 
If the temperature decreases, then the levels of phosphate decrease because heat creates more energy and reproductivity.

The Data Table:

The Materials: Thermometer

Phosphorous Test Tab

Timer/Watch

Phosphate Color Chart Notepad and Pen for Results

The Procedure:

1. Go to my Experiment Site.

2. Put the thermometer in the creek.

3. Record the temperature of the water.

4. Put a Phosphate Test Tab into the water.

5. Wait 10 seconds.

6. Take the Phosphate Test Tab out of the water.

7. Let the Phosphate Test Tab dry.

8. Compare the color of the water with the Phosphate Color Chart.

9. Repeat steps 4-8 three times in the creek.

10. Record results in data table.

Controlled Variables:

1. The River/ River Spot

2. The Litmus Paper

3. Thermometer

4. How Many Tests

5. Time Length of Litmus in the Water
