About This Lesson
In our second video podcast, we find out that scientists are sniffing around for a way to develop an electronic nose. For almost 25 years, chemists and other scientists have tried to build a machine that can take a whiff of the air, food or other objects and say whether the odor is nasty or nice. Such a machine could work in factories, and help tell whether food is fresh. An electronic nose also could sniff for harmful air pollutants. And unlike people, it could work 24 hours a day and 7 days a week without getting tired.
This video would be great intro to a lesson on smell and how it impacts our sense of taste- Such as students holding their nose and eating a "random" jelly bean and try to guess the flavor without smell
