With the help of a labelled diagram,describe an activity to show the particles of matter are very small. Use the following materials that have been provided to you:
Four beakers, three test tube, dropper, distilled water and few crystals of potassium permanganate.

Solution
Procedure for the activity:
Dissolve a few crystals of potassium permanganate in 100 ml of water.
Take out approximately 10 ml of this solution and add it to 90 ml of clear water taken in another beaker.
Now from this solution, take 10 ml of the solution and add it to 90 ml of clear water taken in another beaker.
In the same manner keeps diluting the solutions like this five to eight times.
Observation for the activity:
This experiment shows that just a few crystals of potassium permanganate can colour a large volume of water.
Conclusion:
This activity proves that matter is made up of tiny particles.
So we can conclude that there must be millions of tiny particles in just one crystal that keep on dividing itself into smaller particles.
Certainly a stage is reached when the particles cannot divide further.
