Pathogens spread through either contact with living organisms, through the air, or contaminated objects, soil, or water. In this activity, you will see how pathogens spread in contaminated apples

Procedure:

1. Label the plastic bags 1−4.
2. Put an apple into Bag 1 and seal it.
3. Rub a rotting apple over the entire surface of the remaining three fresh apples.
4. Put one of the apples into Bag 2 and seal it.
5. Drop an apple to the floor from a height of about two meters. Put the apple into Bag 3 and seal it.
6. Wipe rubbing alcohol over the entire surface of the last apple. Put the apple into Bag 4 and seal it.
7. Place all four bags in a dark place for one week.
8. At the end of the week, record your observations.

The pathogens in the rotten apple had spread to the apples in Bag 2 and 3, while the apples in Bag 1 and 4 remained fresh because pathogens were not peresent or were killed.

What are pathogens?

Pathogens are disease causing organisms which are spread from one person to another directly or indirectly.

In the following experiment, a rotten apple contains pathogens which can spread by direct contact to the other apples.

At the end of the week, the apples in Bag 1 and 4 remains relatively fresh because the pathogens that were either not present it were killed when in contact with rubbing alcohol.

The apple in Bag 2 had gone bad while that in Bag 3 had gone bad the most.

Therefore, the pathogens in the rotten apple had spread to the apples in Bag 2 and 3, while the apples in Bag 1 and 4 remained fresh because pathogens were not peresent or were killed.
