Question 1.
Using your imagination, and information from other sources, describe anyone stall in detail.
Answer:
I visited a stall at the Science Fair. The theme of the stall was ‘Energy’, The experiments shown were to produce electricity at home and the method was very simple, but the part of the experiment was that it was so simple that anyone could try it out themselves at the stall.

  • The prize winning project was how to make lemon Battery.
  • The aim of the experiment was to make Lemon Battery.

The material used were 2 lemons, Copper wires, 2 large paper chips, 2 coins, a digital clock, scissors and a knife.
Besides the Lemon Battery Projects, there were other projects which focussed on the use of Kinetic Energy, Uses of Potential Energy, Electrostatic Energy, Sound, Food adulteration, Mechanical Energy and Fun with Magnets. Also Charts were put up best with bold writing.
