Relate Time Units (Seconds, Minutes, Hours, Days)
ā³ From heartbeats to years! How do the tiny units of time fit into the giant units of time?
Concept
Just like 10 pennies make a dime... time has exchange rates too! šÆ **The Time Exchange Bank:** * **1 Second:** Super fast. One heartbeat. (Snap your fingers). * **60 Seconds -> 1 Minute:** Washing your hands. Microwaving a hot dog. * **60 Minutes -> 1 Hour:** Watching a long cartoon movie. One class at school. * **24 Hours -> 1 Day:** Waking up, living, sleeping, and waking up again. * **7 Days -> 1 Week:** Monday, Tuesday, Wed... etc. * **52 Weeks (or 12 Months) -> 1 Year:** A birthday to your next birthday! **The Golden Question:** "Which is longer? 2 minutes, or 20 seconds?" * 2 minutes is 120 seconds! It is way longer!
