Distinguishing and recognizing odors


Experimentation instructions for Experimento | 4+:
Can our nose distinguish various smells from each other? Can we recognize something from the smell alone?

Text (75.3 kByte)
Smells are transported through the air. They generally reach the olfactory cells by being breathed in through the nose. When a scent attaches to the corresponding sensory hair on the olfactory cell, an electric stimulus is triggered which is forwarded directly to the brain and processed there.

Information and Ideas:
• The teacher/educator should collect things that have a particularly strong, characteristic smell, such as fruits, herbs, spices, and fresh wood.
Things with a very harsh smell like vinegar, or dangerous substances like gasoline should not be used. Children must not swallow any of the items collected.
• Please observe the general safety and hygiene measures and safety instructions in the respective teaching methods as well as the applicable safety guidelines for your school.
• All materials mentioned in the instructions will have to be purchased directly from commercial sources.
