Below are the ideas for science exhibition model:
  1. Image formation by lenses
  2. Simple microscope using convex lens
  3. Working  of Human eye (using convex lens and screen)
  4. Working of electric circuit for a light bulb
  5. Use of Series and parallel circuit
  6. Ohm's law and Joules heating law
  7. Working of electric motor
  8. Direction of electric current in a conductor using compass 
  9. Demonstration of fleming right and left-hand rule
