Working in pairs, students chose everyday objects containing circles, drew them with paper and pencil, and then determined the equations of the circles. Some of the objects chosen were designs in church walls and windows, the logo of the Olympic Games, and the pattern in a tiled street. The results from the different groups can also be viewed in a PowerPoint presentation: http://www.schulnetz-hamm.de/beisenkamp/projekte/uonline02/praesentation.htm Schwarze invites other students to share similar explorations of real-world objects that feature circles. Available in German, French, and English. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- THE GAME OF CHAOS - Juergen Giesen http://www.jgiesen.de/ChaosSpiel/ChaosEnglish.html This applet plays the chaos game at varying speeds. How will the points be distributed in the triangle? Since throwing the dice is random, must the points be scattered "chaotically?"
