The Orders of Magnitude & Scale bundle ,at its core, is a web site lecture tool that includes questions, games, quizzes, video and two experiments that cover the concept of orders of magnitude and illustrate how variables can change with a change in scale.
The first lab is called the Styrofoam Ball Toss. Students take data of the distance they can throw balls of various sizes and try to find a straight line relationship with one or more variables. The end result is both surprising and illustrates the effects of a change of scale.
The second lab is called Orders of Magnitude and is a flash based simulation. Students take measurements of objects at various orders of magnitude and investigate the effects of their measurement instruments and size of the sample on precision and significant digits.
The materials and all materials are provided in a Zip file. All of the materials and handouts can be accessed from the web site after double clicking on index.html.
