About This Product
The teacher places the students’ own country on the dark side, then turns the globe from west to east so that it crosses the terminator into daylight. Continuing the rotation shows the 24-hour cycle of dawn, day, dusk and night, why sunrise reaches continents at different times, and gives a first look at how the tilt changes day length through the year.
Frequently Asked Questions
Does the Day and Night Working Model show the seasons?
Its main use is the day and night cycle, but the globe sits on a 23.5-degree tilt, so teachers can use it to introduce how the tilt affects sunlight through the year.
Can the LED lamp be replaced?
Yes. The LED has a plug-in connector and can be replaced.
