After this activity, students will be able to Describe how the elevation of an object is measured. Combine compass directions and elevation to find celestial objects. Summary Students have very little experience with angular measurements. The quadrant provides a simple device with which to measure the elevation of celestial objects, by day or night. People have observed the sky to help them navigate for thousands of years.
Astronomers use the same kinds of angular measurements to find the objects they want to observe.
Ask students to think of a way to safely measure the height of the sun. Remind them never to look directly at the sun. Read instructions together and assist students in construction. Emphasize the dangers of looking directly at the sun. Then show students how to use the quadrant to measure the height of the sun by letting the sun shine through the tube at the top.
