Product Code : SCL-GLE-12904
A working model of the planetary system with a 'Star dome' making it a
versatile aid for teaching basic astronomy. The planetarium comprises a
circular base on which the model planets revolve around the Sun at their
correct relative speeds. The upper edge of the base has a calendar and a degree
scale for setting the planetary positions. The star dome is of the northern
hemisphere.
- Supplied
with teaching manual covering history, the Sun, planets, comets and space
exploration as well as useful tips for demonstration.
- Complete
with all accessories, and a 240V mains power unit fitted with double
insulation and thermal cut-out for overload protection,
- It
is supplied with a star dome for the northern hemisphere.
- This
orrery is suitable from Key Stage 2 to University levels of education.
The model enables the study of the following topics:
- The
Planets in their orbits (length of a year, inferior and superior planets)
- The
phases of Venus
- The
Moon and its phases (external light source required)
- Eclipse
basics
- Time
- solar, sidereal and G.M.T.
- The
ecliptic and the Zodiacal constellations
- How
the planets appear to move against the night sky
- Use
of the Helios outside at night - where should the stars appear in the sky?

for demonstration to Key Stage 2 students, and for student use up to
University level.
Learning Outcomes
- Key
Stage 3 Physics - Matter: Our sun as a star, other stars in our galaxy,
other galaxies.
- Key
Stage 4 Physics - Space Physics: The main features of the
solar system.
- Key
Stage 4 Physics - Motion and Forces: Non-contact forces: gravity
forces acting at a distance on Earth and in space, forces between magnets,
and forces due to static electricity. Relate linear motion to our other
relative motions, such as the earth’s relative to the Sun.
