Trigonometry Class

The advanced algebra class at Middle School South has begun their trigonometry unit. As part of understanding angle of elevation and the use of the trigonometric ratios, the students built hypsometers (an instrument for measuring height or elevation). They used a straw attached to a protractor for sighting, and a string and a paper clip as the plumb line to read the angle on the protractor. They then attempted to use the device to calculate the height of the flag-pole and the height of the ceiling in the commons area. Besides achieving a deeper understanding of trigonometry and its uses, they learned how hard it can be to take accurate measurements.
