Lesson Plan

Smells

Summary: 
Discover the molecular mechanism of smell through smell activities.
Science content (2016 curriculum): 
Biology: Sensing, Organ Systems (4, 5, 6)
Procedure: 

Indoors, run the smells in the air demonstration, to show that a smell is molecules floating through the air that reach our nose. (It will not work well outdoors with a breeze that blows molecules away.)

Do a selection of the other activities that relate to smells:
Visual deprivation walk to use our sense of smell when sight is lost.
Taste candy/ice cream with no sense of smell, to find out how taste relies a lot on smell.
Visit a garden or store to smell (and identify) herbs and flowers.
Make perfume with herbs/fruit peels/flowers.
Cook an aromatic snack e.g. oat bars, and compare the ingredients' smell before and after cooking.

Notes: 

Gordon Elementary science club did Smells in the Air Demo, Oat seed bars, Perfume making.
isas Spring 2017 did Smells in the Air demo, visual deprivation walk with visit to a plant store to smell and ID herbs, Tasting without smell at an ice cream store, Perfume making.
