PAPER SCIENCE by Harry Milgrom


Email this review


The only thing that these suggested activities have in common is that you can do them all with paper. Some are just exercises in observation--e.g., tear a piece of newspaper and look at the torn fibers under a magnifying glass; drop a paper tube and see if it bounces. (Why? Because ""Rolling the paper into a tube gives it the spring it needs."") Other entries answer set-up questions: What kinds of paper float? How strong is wet paper compared to dry? Some are tricks readers might pull on their friends: Can you knock down a book by blowing? Or support a book with a sheet of construction paper? And others consist of making a simple paper airplane, spring, Mobius strip, or whatever. But the activities aren't arranged to lead to any understandings, and though offhand explanations occur (""the pointed shape of the airplane helps it slice through the air""), there is no orderly elucidation of basic principles. A filler.
