What In The World Do You Smell?
Author: Sharon Janulaw
Overview: Students take a walk outside and use their
sense of smell to discover odors in their world. They record their observations and
compare their observations with those of their classmates.
- We learn about the natural world using our senses and extensions of
Grade Span: K2
- Clipboard with paper for each student
- Container with pencil and crayons for students
Put paper on clipboards.
Prepare containers with pencils and crayons.
Select the area in which you will take the smelling walk.
Time: 30 minutes
Grouping: Whole class
It is essential for children to learn that rational thought and
the scientific enterprise are based upon observations, both direct and indirect. Observations
using our senses and extensions of our senses are the starting points for knowledge that reaps
benefits for our daily lives and contributes to scientific understanding.

Make sure your students understand and agree to follow guidelines for
expected behavior on the smelling walk.
- Talk about the sense of smell. Ask students
what they know about the sense of smell. Which body part do we use
when we use our sense of smell? Talk about words that can be used
to describe smells. Differentiate between words that describe smells
and words that describe how one might feel about the odor. Saying
that something smells strong or smells like vinegar, etc., describes
the smell. Saying that something smells gross describes how one feels
about the odor. Have students sniff the air. Have them share the odors
they think they can smell inside the classroom.
- Talk about rules. Tell them they will go on
a Smelling Walk outside. They will have a clipboard on which to record
what they think they smell because of the odor they are detecting.
Explain that they can draw the object they think they smell and write
the name of the object on their clipboard. They can also write a descriptive
word for the odor.
- Give each student a clipboard with paper and
a container with pencil and crayons. Have each student draw a nose
at the top of the paper and write the words, I Smell...
- Take students outside. Tell them you will walk
and stop a few times. Each time you stop, they will sniff the air
to detect any odors. If they do smell an odor, they can draw what
they think is causing the odor and write its name. They can write
a word that describes the odor.
- After they have had the opportunity to draw
several objects that they discovered through their sense of smell,
have them share by standing in a circle. They will each have a turn
to tell one odor they noticed and to identify the item that was causing
the odor. For example, I smelled something that smelled like
oranges and the flowers on the mock orange bushes were making that
- Return to the classroom and make a list of odors
that were smelled. Have students help you spell the names of odors
as you record. Discuss similarities and differences in what was observed
through the sense of smell. Have them share what they discovered that
they had not noticed before.
Just before students enter the room in the morning or after recess or lunch,
open a container of a substance such as peppermint, orange flavoring, cinnamon, etc. and place
it where students cannot see it. When students arrive in the classroom, tell them you want them
to use one of their senses. When they notice something different, they should raise their hand
to tell you that they notice something. Have them put their thumb up when they raise their hand
if they think they know what it is. Do this more than once. Notice how long it takes for the
students to detect the odor. You can keep track of how accurate their identification of the substance
they are smelling is.
