Question

Explain how can you say that all the matter is made up of particles with experiment

Answer 1

Answer:

Take a soccer ball (or other ball) and tell your pupils it represents the Earth. Hold it out in your left hand and move your right pointing finger slowly towards it from a distance as if it were a spaceship coming back to Earth. Tell pupils to raise their hands when they think the spaceship has reached the air. (Note when the hands go up.) Stop when you are a few millimeters from the surface of the ball. Tell them, ‘Here! Here is where the air starts.’
