Title: (Task) Clinometer Project
Course: HBUHSD Geometry Resource Course

This is an activity with applications of trigonometric ratios. Students make clinometers with protractors, then they use them to measure the angle of elevation to tall objects. They then measure the ground distance and use trigonometric ratios to determine the height of the objects. Critical thinking an applied problems are included.

Teacher Instructions: Teacher will assign groups of 3 or 4.  Teacher will need one protractor, heavy duty thread, and a large paper clip per team to make clinometers. The teacher will need on printed packet per team.  Each team will also need a tape measure. Students will need to go outside to measure tall objects such as flagpoles, lampposts, and tall buildings.

Student instructions: Students will be divided into groups of 3 or 4. Each student is assigned a task according the printed instructions. Groups will make clinometers, go out measure the angle of elevation and ground distance to 4 tall objects. They will then calculate the height of the objects taking into consideration the height of the clinometer. They will then answer some critical thinking questions and apply knowledge to word problems.

Time: 30- 45 minutes to collect data.  30-45 minutes to complete task.
