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

HUMANS AREN’T THE ONLY PRIMATES THAT USE MEDICATION.
THE LEFT OVERS
A lot has happened for modern humans to get to this point. We lost most of our hair, learned how to make tools, established civilizations, sent a person to the Moon, and invented artificial intelligence. Whew! With all of these changes, our bodies have changed, too. It’s only taken us about six million years.
SO, WHAT IS A PRIMATE?
What do you have in common with the aye-aye, sifaka, siamang, and potto? If you said your collarbone, you re probably a primatologist—a person who studies primates. If you’re not, read on.
