About This Product
Teachers set the reference meridian or G.M.T. position and then rotate the globe or dial to show how time changes across longitudes. Students compare local times between two cities or meridians, which supports map-reading and global-location exercises in geography, astronomy and environmental science lessons. Export supply of the Time Indicator Manual Model can be arranged to laboratories and schools in Argentina, Rwanda, Gambia, Slovenia, Lithuania and Cambodia.
Frequently Asked Questions
Q1. How does the model show time differences between places? Rotating the globe or dial shows how time changes across longitudes, so students can compare local time at two cities or meridians against the G.M.T. reference.
