The Mystery of the Two Thermometers

Two thermometers measure the very same thing but display different numbers, leaving the Bugville friends convinced that one of them must be wrong. Their investigation reveals two temperature scales—Celsius and Fahrenheit—and shows how each scale uses different numbers to describe matching conditions. From icy freezing points to steamy boiling points, The Mystery of the Two Thermometers helps young listeners compare measurements without becoming lost in complicated calculations. Clear examples, playful clues, and a satisfying discovery introduce degrees, scales, and careful observation while showing that two different answers can both be correct when they use different systems.
