Important Points

  • The objective is to create interest in Physics by inculcating the culture of doing experiments.
  • The students/teacher should be able to DO experiments by using material available locally, i.e., at home or in local market.
  • Just reading or watching videos of these experiments will not help, the fun/learning starts when you DO these experiments. The writeup is provided for initial help.
  • Many writeups are incomplete. They are provided to convey idea on which you can build yourself.
  • We believe in continuous improvement through collaboration. Use contact us form for corrections / suggestions / contribution.
