This guide allow students to determine the height of the school flagpole and compare the heights to which styrofoam and rubber balls can be thrown. 12-14Yrs

Height-O-Meters

Height-O-Meters


  • Grades 6-8
  • Written by Cary I. Sneider
  • A prerequisite to the exciting GEMS unit Experimenting with Model Rockets, this guide introduces the important principle of triangulation (determining location with the use of angles and degrees) and its application in professions from forestry to astronomy.
  • The guide includes a design for simple cardboard clinometers (Height-O-Meters), with which students determine the height of the school flagpole and compare the heights to which styrofoam and rubber balls can be thrown.
  • Students develop skills in predicting, estimating, making and calibrating scientific instruments, measuring in degrees, graphing, calculating, and interpreting data.
  • Going Further activities relate triangulation to the real-life activities of forest rangers and astronomers.
  • Time: Four 45- to 50-minute sessions plus follow-up suggestions.
