In this activity, learners use household materials to investigate and explore their ability to smell an odor. Learners compare and contrast results to determine if some individuals have a better sense of smell than others. Learners also observe the Maillard reaction and how different odor molecules are released into the air. Note: Since experiment #2 requires the use of a hot stove and skillet, we recommend that an adult conducts it as a demonstration, or that the appropriate safety materials are used and safety guidelines are discussed prior to the experiment.
