Spread of Micro-Organisms
Students had performed the activity to show how microorganisms spread from one from one person to the other by using glitter powder.(Here glitter represents microorganisms). They had spread glitter on their hands and touched their friend’s hand. The Students observed that glitter from the hand of a friend sticks to the other. The result was that microorganisms spread from one person to the other by contact.
