Using
Real-Time Data on the Internet
Background
Using Real-Time images or data on the Internet instead of information out of
a textbook not only engages students, but also brings a real world
connection right into the classroom.
Is it Real-Time?
Real-Time data on the Internet does not necessarily mean that the
information is available the moment it is collected, but rather any data or
information that is updated on a regular basis and frequently changes.
For example, new weather satellite images updated every hour are actually
referred to as "Real-Time data."
When were the data last updated?
Most sources of Real-Time data will have a clock or time stamp that shows
the time and date the data were last recorded. Frequently, the time is
expressed in increments of 24 hours and as standardized universal time, such
as Greenwich Mean Time (GMT), Coordinated Universal Time (UTC),
etc. Students may have difficulty comprehending the difference between
standard and local time so it might be worthwhile to review the following
sites:
NOTE: If the images or data have not changed
recently, you should first click the Reload/Refresh button; this forces your
computer to retrieve the most updated information on the Internet.
