We sent email to students in Professor Richard Zimmer's Mars Society course at Sonoma State University, Fall 2003. One of the students had been assigned the task of measuring the heights of tall objects on the SSU campus. We suggested ways to measure the height of the tall object: 45-45-90 Degree Triangle Method The clinometer method The Defy Gravity, or Fly-on-the-Wall Method The Defy, then Use Gravity Method The What Goes Up Must Come Down Method The Hot-Air or Helium Balloon Method The Kite Method The Statistical Survey Method

Reviewer Comments:

Content here is the 45-45-90 triangles and distance story problems. The activity requires some materials and set up that are not listed but provides a hands-on activity in the classroom or outside your window. The CRT likes this resource because it is not too often one finds an activity that spans application at many instructional levels; adaptations from geometry to trigonometry seem to apply here. The CRT notes there are no suggested student responses.
