Time investigators!


Posted by moya | Posted in Uncategorized | Posted on May 5, 2014

1/2LT started looking at time today. We made our own clocks to use as we explore this new concept. However, we did have one question. Can you help us find the answer?

Why are the numbers on a clock 1-12?

Let us know your ideas. We’re looking forward to discovering new things as we explore time.

The 12 hour system was in use in Egyptian times, although explain actions for how this arose vary. On theory is that 12 was a more common counting unit due to counting knuckles on fingers rather than fingers them selves as we do now. Or it may be related to the stars used to mark the passing of time.

Explanations not explain actions 🙂

There are 12 hours on a clock, because the 24 hours of the day are divided into two periods:[1] a.m.(from Latin ante meridiem, meaning “before midday”) and p.m.(post meridiem, “after midday”).[2] Each a.m.,p.m. period consists of 12 hours numbered: 12 (acting as zero), 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and 11. The 24 hour/day cycle starts at midnight 12a.m. and runs through to noon 12p.m. Then, another, new day starts over again at midnight 12a.m. (From Wikipedia)
