Record on the activity sheet. Proceed to each designated object. The recorder measures and records the constant's shadow. Then measures and records the shadow of the object. Return to the classroom and calculate the approximate height of the objects measured by using proportions.
Students work in partners or groups.
Following the procedure outlined in Activity 1, student partners or groups measure the shadow of the pillar and compute the approximate height. Groups compare results and come to a consensus about the approximate height of the pillar. Compare their results to the actual height.
