When going uphill, normally it will take more paces to go 100 meters. Going down hill will take fewer paces. Test student understanding by having them determine the distance of a premeasured course by pacing off the distance. Students may determine the height of an object by a indirect method. A clinometer or improvised Hypsometer-Clinometer and a Table of Tangents along with a measuring tape or accurate pace count may be used to determine the height of a object.
Students measure a base line distance away from the object to be measured.
The student then uses the Hypsometer-Clinometer to determine the angle to the top of the tree. This gives you the height of the object. The mural wall is a excellent place to set up measuring points. After the students have computed the height of the wall at various points, measurements may be taken using a 50 meter tape from the top to the bottom. Have students first estimate the height of the wall, then compute the height, then record the tape measured figure.
