Have you ever heard of a clinometer? Have you ever thought about how tall a tree actually was, or if they ever took the time to really measure the height of the Empire State Building. The answer is, yes! Some people have very inquisitive minds. They wonder things like the distance between their favorite star in the sky and their backyards. These people are the minds that usually turn into great thinkers later on in their lives. It’s not impossible to calculate the distance between your favorite star and your backyard. The instrument is called a clinometer. Astronomers and other scientists use clinometers to determine how tall something is like a tree or skyscraper. They also use this instrument determine the how far something can be viewed in the sky in degrees. A real clinometer can be obviously expensive. However, there is a way for you to make your own home made version. They are very effective and they work-even if you made it yourself.

Suggestions & Ideas

• If you have chosen to construct the protractor yourself out of heavy board, mark the increments on the item in five degree intervals. You won’t to be accurate.
• Be sure to use only heavy duty cardboard or poster board to make this protractor. Any other material can be way too thing and tear under the weight of the washer and string.
• In order to use your new clinometer, view any object via the drinking straw and record not where  the string is hanging. subtract that from ninety. That’s elevation calculation. Now, measure horizontal distance the thing you are measuring  and yourself. Also, measure the vertical distance between eye level and the floor.  This may be easier if you have a friend to help you.
