Ecosystem Journal Check


December 27, 2010

3:14 PM

Detailed Weather: 

Wind - 
  • It was slightly windy.  Not a whole lot of wind, but enough to feel it blowing in your face.   
  • Beaufort Scale: 3
  • North: I confirmed this by bringing a compass and measuring 
Clouds - 

  • There were a few whispy clouds.  Not a whole lot, only in the higher areas of the sky.  
  • They were very pure white, almost blending in with the sky which was not blue. 
  • cirrus clouds.  
Temperature -


  • Air: 24° Fahrenheit
  • Fahrenheit to Celsius: 
     
C = (24 - 32) x 5/9

C = -8 x 5/9

C = -8/1 x 5/9

C = -40/9

C = -4.444444444444444444

  • -4.4444444444° Celsius
  • Water:  The water was frozen over because of the snow storm!  I tried to break some of the ice to measure the temperature but it didn't work. 

General Observations: 

Measurements - 

  • Bur oak tree branch - 65 inches 
  • inches to centimeters conversion - 
2.54n = c

2.54(65) = c

c = 165.1

  • bur oak tree branch = 165.1 cm
  • water depth: NA
  • water temperature: NA

Biota - 

  • 2 bur oak trees
Differences from previous months - 

  • Seasonal changes: 
    • The air was finally cold enough to freeze the creek!  It is getting colder and we are officially in winter now.   
    • I am required to visit earlier now because it gets dark so much earlier
  • my bur oak tree "measuring branch" is not growing as quickly as it was before.  This must be because it is no longer growing season.  
  • There was snow on the ground!  It was very difficult to walk through my ecosystem because there was more than a foot of snow on the ground!
