Newton’s law of cooling states that the rate at which an object cools is proportional to the difference in temperature between the object and the object’s surroundings. Simply put, a glass of hot water will cool down faster in a cold room than in a hot room. This simple principle is relatively easy to prove, and the experiment has repeatable and reproducible results.
Adapted from a creative statistics lesson taught by master science educator Mark Krotec, this pre-lab investigation introduces the value of statistics, the inherent qualities of uncertainty, and data interpretation. Students are asked to discredit the claim that their teacher possesses psychic ability by using a clever card trick, a careful experimental design protocol, and the application of the chi-square test.
