Shark Sense of Smell

This is an activity about our sense of smell and how it compares to sharks' super noses. Learners will create varying solutions of water and perfume. Can you smell a single drop of perfume in 500 ml of water? Sharks certainly can! The experiment uses only a few simple materials, and is a great way to begin talking about human and animal perception. [Activity is publicly available through a web crawler capture on Archive.org.
