Well, it’s about time!!!

What time do you get up in the morning? What time do you go to school? How much time does it take you to eat your lunch? What is your bedtime? What time is it now? We ask questions about time every day. Or rather, to put it differently, we live questions about time every day.

Growing up in the 1970s, 80s, and 90s in the United States, my friends and I mostly used battery powered wrist watches to ‘tell’ time. Nowadays, my middle school students mostly use battery powered smart phones and, most recently, various brands of smart watches. But if you really want accuracy and precision in your time keeping, you will follow an atomic clock.

What is an atomic clock? How can atoms keep time? Watch the creative 2 minute video below and see if it is able to answer some of these questions (and others)…
