About This Product
Turning the arm until the Moon sits between the Sun and the Earth casts a small umbra on part of the globe for a solar eclipse; turning on until the Earth is between the Sun and the Moon shows the Earth’s larger shadow covering the Moon. Tilting the orbital plane by 5 degrees shows why eclipses do not happen every month, and the umbra and penumbra help explain partial and total eclipses. Schools, colleges and institutes in Togo, Zimbabwe, Cameroon, Morocco and Guinea can order the Solar & Lunar Eclipse Manual Model STEM Lab from Educational Instrument.
Frequently Asked Questions
Why does the Solar & Lunar Eclipse Manual Model have an adjustable orbital plane?
It lets the teacher set the Moon’s orbit at its 5-degree tilt, showing why the three bodies line up for an eclipse only on some orbits and not every month.
Does the model need a dark room?
It works in normal classroom light, but the umbra and penumbra are easiest to see in a semi-darkened room.
