An experimntal tool for changing altitude by season

摘要

This design makes it easy to measure the change in the altitude of the sun according to the change of the season, the change in the length of the shadow and the amount of sunlight reflected on the surface, as well as the natural phenomenon at a glance. The present invention relates to a laboratory apparatus for changing the altitude of the sun according to the season.;The present invention is to install a transparent hemisphere 11 on a horizontal flat plate 10, to install a vertical axis of rotation 12 inside the transparent hemisphere 11, the inside and outside of the transparent hemisphere 11 A pair of inner and outer magnets 15a and 15b which move together by magnetic force is installed, and the inner magnet is connected to a thin line 16 at the lower end of the rotating shaft 12, and according to the movement of the inner magnet. In order to measure the angle of the variable string 16, a protractor 13 is installed on the rotating shaft 12, and a semicircular orbital member 17 that represents the trajectory of the sun is installed outside the hemisphere, and the rotating shaft 12 The light irradiation port 20 for irradiating light toward the sun is configured to be movable along the orbit of the sun.
