All modern science and technology—from cars to cell phones to cameras to electric lights to power plants to clothing and grocery items—relies on the ability to measure length, volume, mass, voltage, power, temperature, pressure, brightness, and much more. Any STEM discipline, beyond simple qualitative learning about the wonders of God’s creation, has its own measurement needs and techniques. Jeanne Bendick has published many books on STEM topics, written in beautifully clear, simple, entertaining prose and illustrated with simple yet informative drawings. Her book How Much and How Many: The Story of Weights and Measures triumphantly explains the history and science of measurement for advanced elementary through middle school readers.
Reading and absorbing the information in this book will support any STEM topic a child is studying and is also immensely practical, since everyday life depends on measurement science—the science of how much and how many. At home or out and about, notice how much you rely on accurate measurement: buying 1.5 pounds of lunch meat at the grocery store, talking to a policeman who has measured the speed of your car with a radar gun, or filling your fuel tank with precisely 9.7 gallons of gasoline. If your high school student becomes interested in learning more about measurement science, visit www.nist.gov, the website of the National Institute of Standards and Technology (where I worked for 36 years), the federal laboratory dedicated since 1901 to ensuring accurate weights and measures in the United States.
