πŸ“β€‰β±β€‰πŸŒ‘ HAPPY WORLD METROLOGY DAY!

20 May 2023 by Bob O'Hara

It’s World Metrology Day! On this day in 1875, the meter was adopted as the standard for the metric system of measurement, and the rest is history. πŸ“

Poster for World Metrology Day 2023. (AvailableΒ fromΒ worldmetrologyday.org.)

Metrology is the science of measurement, and it serves as a foundation for all other branches of science (not to mention commerce, industry, and daily life). Can your students recognize the basic measurement units that comprise the International System of Units (SI), better known informally as the metric system? We measure the universe in seconds (s), meters (m), kilograms (kg), amperes (A), kelvins (K), moles (mol), and candelas (cd)Β β€” and any student going on to study science in high school or college should know how these standard metric units (SIΒ units) work.

Take a look at just a few of the places that scientific and engineering measurements interact with your life every day:

You can download and print your very own copy of this year’s World Metrology Day poster at worldmetrologyday.orgΒ β€” it’s just the thing for your homeschool bulletin board! And if you have any serious stamp collectors in your homeschool, there are hundreds of metric-system stamps and SI-system stamps you can explore from countries all around the world.

What scientific measurements have you taken in your homeschool this Leo Term? 😊

❑ Make it personal: Weights and measures may not seem like an engaging topic to some people, but it’s been central to civilization for thousands of years. (Just ask the ancient Egyptians, Israelites, and Greeks.) We live in a world of inches, miles, meters, and millimeters; grams and pounds; light-years and amperes; seconds, drams, and degrees. If you want to have some fun in your homeschool this World Metrology Week, why not invent your own measurement units and apply them to everything around you. If you do, you’ll be entering into an ancient and honorable tradition.Β βš–οΈ

❑ Explore more: For a quick homeschool review of the metric system and other systems of weights and measures, turn to page 364 in your River Houses almanac.Β πŸ“š
