Instructional Ideas

• Without showing students what you're doing, cut a lemon in the back of the room and have pupils raise their hands when they can smell it; discuss the sense of smell before showing the video
• Have discussions about behaviors that can destroy your sense of smell such as smoking or certain drugs

Classroom Considerations

• Use closed captioning to help learners follow along due to the speed at which the narrator speaks

• This video is hosted on YouTube

Pros

• Engaging hook about a woman who lost her sense of smell
• Interesting portion at 7:20 about how our tongues don't have specific areas for specific tastes, pointing out that what students learned in elementary school is incorrect

Cons
