Flatulence (farting) is a chemically based process. Most of the gas emitted by the back end of a human’s digestive system is nitrogen and carbon dioxide, ingested when swallowing food and drink. However, the final mix can also contain methane and hydrogen sulfide generated by beneficial intestinal bacteria that break down food materials, mostly cellulose fibers, that the human body cannot.
This is a fun quiz or activity that can be given individually or in cooperative pairs when you are teaching stoichiometry and Avogadro’s law of gases. Students will learn about flatulence as they are assessed on their calculation skills. My students laugh out loud at this one…
The activity is appropriate for high school chemistry or GTE middle school science if you are studying stoichiometry.
This activity is free. I would appreciate you rating it after downloading and using it.
