Surveyors and engineers use special equipment to measure these distances and angles accurately. The instrument they use to measure the angle is called a theodolite. In this activity you will make a simple theodolite. You won't get accurate answers, but it will help you to understand how surveyors do their work.
Make a clinometer.
Draw a diagram to show how you might use this to find the height of a building. Be sure to include all the mathematics you need.
Research how to use trigonometry in right triangles to calculate the height of a building
Research how to use a theodolite and create model using your clinometer to demonstrate to your classmates.
Did you notice anything wrong?
Where was your eye when you measured the angle θ?
Can you think of a way to compensate for error?
How does your clinometer compare to a theodolite?
Create a piece of media that explains clinometers (print, video, website, digital production, paper display etc)
Present a Q&A session for your classmates
