Chapter Summary
Understand that weather is the state of the Earth's atmosphere at a specific time and place, and that nearly all weather phenomena occur in the troposphere, the atmospheric layer closest to the Earth.
Identify and define the five key components that constitute weather: temperature, precipitation, atmospheric pressure, wind, and humidity.
Learn about the instruments and scales used to measure temperature, including thermometers and the Celsius and Fahrenheit scales. Understand the concept of ambient, maximum, and minimum temperatures.
Understand how precipitation, particularly rainfall, is measured using an instrument called a rain gauge, and how to interpret rainfall measurements in units like millimeters (mm).
Recognize that meteorology is the scientific study of weather, which forms the basis for modern weather forecasting. Meteorologists use scientific instruments and data to predict future weather conditions.
Appreciate that before scientific instruments, people used traditional knowledge, such as observing the behavior of animals (ants, frogs) and plants (pine cones), to predict upcoming weather changes.
Learn how to perform basic calculations with temperature data, including finding the 'range of temperature' (maximum minus minimum) and the 'mean daily temperature' for a given period.
