Author Description

Excerpt from The Story of the Earth The science of our schools is, in a word, quantitative. That is, it concerns itself with exact measurements, accurate data, rigorous experiments, and demonstrations of laws which have to do with quantitative relationships. Hours are spent, for instance, in some of our high school laboratories, in the exact deter mination with a vernier caliper of the coefficient of expansion of aluminum. Such experiments are liable to be tedious, require much time, and thereby greatly limit the scope of the sciences taught. They are, moreover, entirely out of the reach of our elementary schools.
