Try to measure the shadow of your meter stick as close to the dates listed
as possible. If you don't have school on the dates given, or if cloudy
weather makes measurements impossible, simply make a note of the date
on which you did take your measurements. They will vary substantially
over the months, so a few day's difference won't be significant.
Day of Measurements
1) The actual time of high noon depends on your location in your time
zone. (It's noon at 12:00 pm only in the middle of the time zone. On the
eastern edges, noon arrives before 12:00; on the west edges, noon arrives
after 12:00.) Your local noon takes place exactly halfway between sunrise
- To calculate
local noon, insert your state and city or town in the form on the following
Web site. Then find the time that's halfway between sunrise and sunset.
Sun and Moon Data for One Day
Daylights Savings Time, time shifts later by one hour, so noon occurs
at 1 p.m. (in the center of the time zone.)
If you're exchanging data with another class, figure out what works best
for you. As long as you make your measurements at the same times and on
the same dates, you will be able to accurately compare and contrast data
from two geographic locations.
