Apologia Physics

We made clinometers in class first thing.  Why?  They use tangeants!  They also go along with problems related to the height of any object.  I had made clinometers when I studies forest biodiversity.  Clinometers are used to measure tree height.  We used the ceiling height in the Maker Lab of the library because we could get a measurement to check the accuracy of the measures with a clinometers.  (In writing this, I realized I hadn't instructed the guys to calculate the percent error.  Whoops!).  Justin's measures matched ours because he took the angle of the protractor while Kolbe eyed it, insuring better accuracy.   Here are the photos.
