 Lesson:
"You're Going to Bed at What Time?"
As you know, the sunrise/sunset times are provided using
the 24 hour clock or military time, which divides the day
into 24 hours. But most of us don't use this timekeeping
method very often. (When was the last time your students
were told to go to bed at 22:30?!)
1)
Think! Journal Question
Most
of the "time", our days are divided into 12 hour
sets, one for "A.M." and one for "P.M.".
Ask
your students "What do you think the initials 'A.M.'
and 'P.M.' stand for? Why do you think these abbreviations
were created?" Have them write answers in a journal,
and then discuss.
2)
Try It! Test your Parents
Have your students determine what their own bedtime is using
the 24 hour clock/military time. Then, have them ask their
parents if they know what that bedtime is using the 24 hour
clock. For example, "is it ok if I go to bed at 23:30
tonight?". Do the parents know what time that is? (If
they don't know, have students give them a helping hand and
explain the 24 hour clock of timekeeping) |
