They explain the different results by referring to the degrees of prevision of the different measurements. In making a scale drawing of a house, students discuss the degree of accuracy of their measurements. Students read and discuss the photographs in Powers of Ten by Phillip and Phylis Morrison and the office of Charles and Ray Eames, and view the associated videotape. This wellknown book takes the reader on a trip through perspectives representing fortytwo powers of ten, from the broadest view of the universe to the closest view of the nucleus of an atom. The measurement units used and the progression from one to another highlight the range and power of our system of measurement.
Students use computer drawing and measuring utilities to discover geometric concepts.
They also discuss the limitations of such a program. Students determine what kind of measuring instrument needs to be used to measure ingredients for pain-relievers, for cough syrup, for a cake, and for a stew. They discuss the accuracy, error, and tolerance of each measurement. References Morrison, Philip, Phylis Morrison, and the office of Charles and Ray Eames. Powers of Ten .
