Mouth Microbes and Chewing Gum

[yellowpeach]

My daughter has been working on an experiment using Cinnamon, Spearmint, and Peppermint chewing gum. She made agar petrie dishes and swabbed her mouth after chewing each chewing gum, and she watched the microbes grow! But the question now is "How is she able to graph something like this?" Do you have ideas of how we can chart this somehow?

Thank You

Hi,

If possible, you can graph your results by counting the amount of colonies in each dish and charting your results in the form of a bar graph. That should be a simple way to make a meaningful graph for the project.

To add to Ivy's suggestions about graphing, I wanted to provide this URL for a Science Buddies resource that can help with bar graphs:
