Sound is fast, but not too fast for you to measure its speed. You and a friend can find out how fast sound travels through air with just a few things you probably have at your house and some math you already know. Don’t worry—a calculator will do the hard part for you. The only thing that could be a little tricky is finding a good location. You’ll need an open area outside a large building with a mostly flat wall. A field next to a school or a parking lot next to an office or hospital usually fits the bill. Ask an adult to OK your experiment location.
You’ll need
A long tape measure (in feet or meters)
Tape, chalk, or stick to mark the ground
Stopwatch or a stopwatch app on a smartphone
Thermometer or a weather app on a smartphone
Calculator or a calculator app on a smartphone
Pencil and paper
A friend or other partner
