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.
