  Inclined Plane Apparatus

  Comprises of a wooden plane consisting of two laminated wooden boards joined together by metal strips at both ends for rigidity. One end of the plane is hinged to a cast metal base, while the other end has a pulley clamp attached to it. This also has arc scale mounted on the base with a circular scale calibrated from 0 to 45°´1° to measure the angle of inclination and vertical scale calibrated in centimeters to measure the height.

  Earth Moon Sun Model Tellurium

  For demonstration of respective positions and the motions of the Earth, Moon, and Venus around the sun. Rotation of the handle makes the earth to move around the sun, while revolving on its own axis, the moon moves in its orbit around the earth, and venus will follows its path around the sun. It also demonstrates the causes of the seasons, day and night, phases of the moon, and many other related phenomena. The large sphere is the sun, with Venus near it, and at the end of 16½ inch arm is the Earth with the moon near it.
