Thermometer Accuracy
In my differential equations class, students ran an experiment on the accuracy of a nondigital thermometer. Most directions for use of nondigital thermometers say to leave under the tongue for 2 minutes, so students tested the accuracy of this. Three groups performed different activities for two minutes (cheweing gum (placebo group), jumping jacks, and drinking a cold refreshing beverage). Students collected temperature readings every 30 seconds for 4 minutes. Data was run through Logger Pro, and students analyzed data using best fit lines.
