About This Product
The dial is set to local time, then the globe is turned from west to east, anticlockwise seen from above the North Pole, and students read off the time for a city on another continent. The model helps explain the 4-minute difference per degree of longitude, GMT, local solar time against standard time, day and night, and the International Date Line in geography and physics lessons.
Frequently Asked Questions
Is the Time Indicator Manual Model battery-operated?
No. It is turned by hand, so students rotate the globe themselves and watch the 24-hour dial move with it.
What does the model show about longitude?
Using the degree markings, students can work out the 4-minute time difference for each degree of longitude and how far a place is ahead of or behind GMT.
