The temperature outside is always changing, which means getting an accurate read on it is important. This informative book shows readers how to measure temperature with a thermometer. Knowing the temperature will keep readers from diving into a freezing cold pool, or ensure they wear light clothes on a hot summer day. Showing measurements in both Fahrenheit and Celsius gives the book added value, and means readers will know the temperature no matter what kind of thermometer they use anywhere in the world.
