IB Mathematics Applications and Interpretations

In our IB Mathematics Interpretations and Applications class, students are not only learning new math concepts, but they are also using these concepts to make instruments and to solve problems they would not have been able to otherwise. The following is a project one of my students completed by constructing and using a clinometer to answer the given questions. A clinometer is an instrument for measuring angles above or below a horizontal line (angles of elevation or depression). A metal tube allows the user to sight the top (or the base) of an object, and a protractor-like device on the side measures the angle. It is used to take measurements of accessible distances and angles, and then use them to calculate inaccessible heights.   The clinometer   The road sign                                         The roof                               The road light   Measurement process       What factors do you think could have affected the accuracy of your measurements and final result? The distance between me and the object must be as accurate as possible, because this distance is estimated by us, and the angle of elevation can be measured by protractor. Suppose you are standing on the third floor of the building and want to find the distance to a building across the street. What information would you need and what measurements would you need to take in order to calculate the distance? Suppose you have the necessary information and have obtained the measurement. Draw a diagram and explain how you would find the distance. How would you calculate the angle of the depression if you know the side measurements? I …
