inform students that they will be working with a partner to measure various tall objects around school today using a few simple measurements and mathematics; one partner will be the surveyor, and the other student will be the recorder. the second measurement will be made using a special tool called a clinometer, used to measure angles of elevation and depression. explain that students will work with a partner to replicate this procedure to indirectly measure the height of tall objects around campus, such as the flagpole, gymnasium, or bleachers. allow student groups to fan out and perform their measurements at each location, providing guidance as necessary. after returning to class, explain to the students that they now have all the information that they need to calculate the distance between themselves and each object as well as the actual height of each object. introduce the three basic trigonometric ratios for right triangles found on math open reference, and how they can be used to calculate an unknown side of a right triangle.
begin an assignment in classkick, instructing students to draw a diagram for each location and label it using the eye-height of the surveyor, the angle of elevation, and the angle of depression. guide the students through the process of calculating the distance between themselves and one object, explaining that everyone will likely have different results due to varying eye-heights and distances stood from objects. allow students to complete their calculations for the remaining objects on their classkick page. (optionally, calculate the average of all student values to determine a more accurate height, which is an application of the central limit theorem). finally, have students complete a google form as a ticket-out-the-door, explaining how to use a clinometer and trigonometry to indirectly measure the height of very tall objects. common sense is the nation’s leading independent non-profit organization dedicated to empowering kids to thrive in a world of media and technology.
