Overview
Long ago people believed that the gods made the weather. They thought gods were responsible for the sun shining, the wind blowing, and the rain falling. Until the mid-1500s, most people had little or no understanding of how the weather worked. Galileo Galilei built the first thermometer in the early 1600s. Later inventors created ways to measure and record the temperature more accurately. Today weather scientists called meteorologists study and report the weather. For more information on weather, read Investigating Storms, another book in the Mission: Science series.
Synopsis
Long ago, it was believed that the gods ruled the weather, because it was a mystery to people. No one knew how to measure heat, cold, or wind. Galileo Galilei invented the thermometer in the 1500s. Soon after, the first barometer was invented to measure air pressure. In other countries, the Celsius scale is used, named after astronomer Anders Celsius. Today, meteorologists use newer tools like weather satellites and radar to make weather predictions.
