Why Are Things Shaped the Way They Are?

David Whiten, Phyllis Whiten 

April 2009, Volume 15, Issue 8, Page 464

Abstract:

Important geometric concepts embedded in the shape and design of natural and manufactured objects. The Whitins first describe fourth graders exploring why manhole covers are circles. Then the authors offer a range of activities to demonstrate how inquiring about shape in botany, geology, biology, and industry can effectively integrate science and mathematics and foster a life-long spirit of inquiry.
