Measuring the Height of a Tree

  • 1.5m
  • Start with making a clinometer by attaching a straw in the middle of the protractor, and tying string and a paper clip to the bottom.
  • Next, find a tree to measure the height of.
  • 59°
  • Firstly, measure the distance from your eyes to the ground. You will need to find someone to help you.
  • 
  • Tan59 = X 3.5 X = 3.5 Tan59 X = 5.824978188 + 1.5 x = 7.32m
  • Next, you will need to measure the distance between you and the tree. 
  • 3.5m
  • Then you must find the angle of elevation of the tree, using the clinometer. Look through the top of the straw at the highest point of the tree. Then get your partner to read the degrees in which the string is displaying.
  • Once you have recorded all your measurements, you must work out the height of the tree. First draw a diagram of your results, placing x where the tree is. Then you must use SOH CAH TOA to figure out the unknown side.
