EDD Diagram w/ NO Data

Hypothesis: If I measure water temperature and air temperature from September to December, then air temperature will have a bigger temperature decrease from the first trial to the last because the air cools down faster than water.

5 Controlled Variables: Same location for air temperature measurement, same thermometer, same amount of time the thermometer is exposed to pond/air, thermometer at same pond depth every trial, measures of variable same every time: degrees in Fahrenheit.

Materials Needed: Thermometer measured in degrees in Fahrenheit,

Step-by-step Procedure: (NEED TO ADD PICTURES)

1. 
   
   
   Expose thermometer in chosen part of pond for 30 seconds. Record degrees in Fahrenheit at 30 seconds.
2. 
   
   
   Repeat two more times and record.
3. 
   
   
   Expose thermometer in chosen plot of land for 30 seconds. Record degrees in Fahrenheit at 30 seconds.
4. 
   
   
   Repeat two more times and repeat.
5. 
   
   
   Average three trials for each variable and record.
