Our First Experiment - How Effective Soap is Against Viruses

Equipment:  soap, water, pepper and a bowl

1. We put water in a bowl.
2. We sprinkled pepper on top of the water.
3. We dipped our finger in and viruses (pepper) got stuck to our finger.
4. We wiped the viruses off with a tissue.
5. We put liquid soap on our finger and spread it all over our finger.
6. We dipped our finger in the bowl and the viruses dispersed.

This experiment showed us how important it is to use soap when we wash our hands.
