In class, we decided to figure how different pollutants affected onions. Our groups each got a different chemical to work with. (My group specifically has Ant Killer) Each day we recorded the average of the root growth of the onion. And on the third day, we added the pollutant. It didn't really do much at first but then it stopped growing and it started to break apart at the bottom.

In class, we are doing a project on the ways onions respond to different kinds of chemicals we feed it. The purpose of this is to see how different things affect the environment when something contaminates water. This is because we are seeing what would happen if it happened to our water. I have learned that onions grow roots when you put it in water and that some different chemicals destroy the roots and make the onion deteriorate.
