Project work: making a clinometer

Method
  • Make a model of a clinometer.
  • From a point inside the school compound, use the clinometer to find the angle of elevation of a nearby tree or of the roof of the school building.
  • Measure the distance from the tree or the school building to the point where you stood.
  • Use the angle and the distance to find the height of the tree or the school building.
  • Take readings from several points on the same straight line, measuring the angle and the distance each time, and find how the angle and the distance are related.
  • Prepare a report and present it in class.
