Make a Clinometer

Materials - Set square
           - Cotton
           - Sellotape
           - Blue tac
           - Cut up Rubbers
           - 1 meter rulers

Task:  To make a clinometer so we are able to measure the height of various objects around the school.

How to make & use a clinometer

After we made the clinometer, we measured: 
- The height of a Norfolk pine = 30.5m
- The height of the toilet block = 3.64m
- The height of a Olive tree = 12.5m to 13.5m
- The height of a goal post = 5.65m
We had problems sighting the clinometer, but with a bit of practice we got it. It took 2 people to make sure the string and rubber was hanging straight.
