Telur Levenhuk - LabZZ - Ediție în limba engleză

Descriere

The Levenhuk LabZZ Tellurium is a desktop mechanical model of the Earth and Moon revolving around the Sun. The tellurium will help children learn why there are seasons, how the phases of the Moon change, and why a year has twelve months. The tellurium is mounted on a stand with a screw. All parts of the tellurium are connected by gears. The Earth and Moon models are operated by turning a small crank. There is also a model of the Sun (with internal lighting) at the center of the rotating mechanism. The Sun lamp is turned on with a button located under its base. The Earth globe rotates around the Sun counterclockwise. You can observe the change of seasons with the help of the tellurium. While the Earth orbits the Sun once, the Moon orbits the Earth 12 times, corresponding to the 12 months of the year. The main elements of this model are made of durable and safe plastic. The diameter of the Sun model is 100 mm, the diameter of the Earth is 85 mm, and the diameter of the Moon is 18 mm.
