Let’s explore how pollution can harm plants. You will need 2 glass jars, celery stalks with the leaves still on, red food coloring, and water. Follow these steps to see what happens.


Question:

Your celery experiment showed how pollution travels through a plant. How could pollution in one small place affect a whole forest or the animals that live there?

If pollution gets into one plant, it can spread to other plants and the animals that eat them. Soon, more plants and animals could get sick. A little pollution in one spot can hurt the whole forest.
