Project Ideas

PROJECT 1.

Calculation of angle of elevation
Trigonometry is around us.In this project we will apply our knowledge of trigonometry to shadows in order to calculate the angle of elevation to the sun at different times of day.
Procedure of Project: To calculate the angle of elevation of the sun go through the procedure

  • Mesure your height and the length of the shadow you cast at two different times of day [at least 3 hours apart]
  • Record the times and measurements [with units]
  • Draw the right triangle in this scenario.
  • label the sides of your drawing with your mesurements and angle of elevation
  • Solve for the angle of elevation while clearly showing all your steps
    Note for teachers
    Don't forget that you need to do the procedure above twice for two different times of a day.
