Design of Educational-kit Model of Geography (Class -6) for National Council for Educational Research and Training (NCERT), New Delhi
The model design for NCERT, New Delhi, demonstrated the concepts of
- Rotation and revolution of Earth and Moon
- the four seasons i.e. summer and winter Solstices, and spring and autumn Equinoxes
Besides, it also demonstrated the eclipses. It also demonstrated the concepts of pulleys and its rotation due to flat and cross rope arrangements.
The low cost model was easy to assemble and in case of any breakdown, it could be easily reconstructed using the readily available materials. With a bearing based mechanism, it was also easy to move and also very accurate in demonstrating different phenomena.
