Measure the height of the school building using its shadow
What you needA stick or a metre rule, a measuring tape, and a sunny day. Two students, because both shadows must be measured at the same moment.
MethodMeasure the stick height and its shadow. At the same time, measure the shadow of the building. Divide the building shadow by the stick shadow to get the scale factor, then multiply the stick height by it.
Do it twice, an hour apartBoth shadows will be completely different lengths the second time, and the building height should still come out the same.
