Measuring the height of Trees

In Scoil Eoin we are very fortunate to have a wide variety of trees growing in the school grounds. We took our clinometers outside to measure the heights of some of the trees.

We attached  a tiny roll of paper on the clinometer. To get a correct measurement you must get into a position so that you can see the top of the tree through the narrow roll of paper.The you must get your partner to check that the plumb line is hanging vertically.

We measure the distance from the the person with the clinometer to the trunk of the tree. Then we had to add the height of the students up to their eye and add it to the measurement.

These Poplar trees grow at the entrance to the school.
