Sample Assessment Ideas

  • Students compete for a prize to be awarded to the student or group that can grow the tallest plant. Share data and ask if anyone was tempted to exaggerate their results. Discuss what effect this would have on the conclusions.

  • Students compete in teams to build and test a model car to see which one rolls the farthest off an inclined plane. Teams will be responsible for monitoring themselves. At the end of the competition, ask if anyone was tempted to exaggerate data and whether exaggeration would be fair.
