======Taste and Smell Connection====== **Materials: **{{$demo.materials_description}}\\ **Difficulty: **{{$demo.difficulty_description}}\\ **Safety: **{{$demo.safety_description}}\\ \\ **Categories:** {{$demo.categories}} \\ **Alternative titles:** Flavor Perception Experiment ====Summary==== {{$demo.summary}} ====Procedure==== - Partner with a friend for the activity. - Close your eyes and pinch your nose shut. - Have your partner place a flavored candy (such as a Life Saver® or gummy ring) in your mouth without telling you the flavor. - Try to identify the flavor while keeping your nose closed. - Continue to observe how the taste changes as the candy dissolves. - Release your nose after a short time and notice how the flavor suddenly becomes recognizable. ====Links==== 📄 Your Sense of Taste - Exploratorium: [[https://www.exploratorium.edu/snacks/your-sense-of-taste]]\\ ====Variations==== * Try with different types of candies (fruity, minty, sour) to see which are easier or harder to identify. * Compare results between people with clear sinuses versus those with a stuffy nose. ====Safety Precautions==== * Use small, hard candies with caution to avoid choking hazards. * Participants should remain seated while doing the activity. ====Questions to Consider==== * Why is it difficult to identify candy flavors when your nose is closed? (Most of what we call "taste" is actually smell; without olfactory input, only sweetness, sourness, saltiness, bitterness, and umami are detected.) * Why do foods taste bland when you have a cold? (Congested nasal passages prevent scent molecules from reaching the olfactory receptors.) * What are the five confirmed tastes, and what possible additional tastes are being studied? (Sweet, sour, salty, bitter, umami; fat and carbonation are possible additions.) * Why might bitter taste receptors be located at the back of the tongue? (To help detect toxins and trigger protective reflexes such as vomiting.)
