Longitudinal view of the Earth enables student to map how hours are derived on the equatorial sundial. There are 24 petals or divisions on the sphere with spacing at 15 degrees each.
This sphere can also be used to represent two hemispheres as well as poles.
Use different filament colors to show regions of Tropic and Polar.
Stand for 18.5 N is attached. But you can design one to suit your latitude when using this as sundial.
- Need 3mm rod as an axle
- Print another copy of the model to represent second hemisphere
- Use one half as an equatorial sundial.
- Use different color filament to represent tropics as well as polar regions . Change filament at 16 mm height for tropics (Blue) and 36.6 mm for polar regions.(White)
