CONCEPT
STATEMENT:
·
Ants are
insects that live in colonies, called nests or “ant hills”. Ants within
the nest have different jobs or roles. Students should recognize the
unique roles of ants (this segment of the lesson focuses on the scout
ants) and their contribution to making the anthill successful. The
importance, types of, and how food is obtained as related to ants’
survival should be acknowledged.
PERFORMANCE OBJECTIVES:
·
SWBAT to indentify
at least 2 sources of food for ants.
·
SWBAT demonstrate
and explain the roles of scout ants (Scout ants search for food).
·
SWBAT explain the
significance of an ant’s scent trail; use and tell how the sense of
smell is important to ants and people.
RESOURCES:
·
For the Drama:
-
1 brown towel,
sheet, or blanket
-
1 bucket
-
1 doll
-
1 lunch bag
-
1 graham cracker
-
several paper ants
made in the previous activity
·
For the whole
group (class):
-
1 bottle of lemon or
strawberry extract
-
1 bottle of
peppermint extract
-
2 plastic Ziploc
bags to hold cotton balls
-
1 piece of yarn 10
yards long (for ant trail)
-
1 plastic grocery bag
-
several extra cotton
balls
·
For each child
and yourself:
-
1 Cotton ball
-
1 cracker
SAFETY CONSIDERATIONS:
·
Prior to determining
which scent extracts to use on the cotton balls, make sure the children
are not allergic to certain scents or extracts they will come into
contact with. Ask parents/guardians before the lesson.
·
Students should be
advised to only smell the cotton balls, and not put them in their
mouths, or too close to their eyes.
·
Determine amount of
space needed to act out the ant dramas, based on the number of students
in your class. A large carpet/rug area would be appropriate; doing this
activity outside might be a distraction for some students, making
classroom management difficult.
·
When students are
“following” the scent trail, make sure they do so, one at a time,
explain everyone will have a turn.
·
An “ant” themed
attention signal could be used if students become talkative, off task,
or aren’t following directions. Photocopy, color, and laminate the
large ant poster from the GEMS guide. Glue it on a craft stick. Explain
to students, when you raise the ant in the air, all students should
freeze and look at the teacher.
SUPLEMENTARY MATERIALS, HANDOUTS:
Teacher:
·
Ant poster from GEMS
guide (p.19)-for attention signal (attached)
·
Setting up for the
Dramatizations directions sheet (attached)
·

ant farm]
2.So they
don’t get out
So they don’t
bite us
They are the
class pet
[So we
can look at/observe the ant’s behavior, CHAMBERS, TUNNELS]
3.Because they
are hungry
[They
need food to survive, and have energy]
|
Relate ants
to students’ personal experiences. Tell students your own experience, “There
were cookie crumbs on the table at my house. I saw ants crawling on my
table!”
Ask students
to share where they have seen ants outside of the classroom.
Call on 2-3
students to share.

Today we
are going to talk about. SCOUT ANTS and their important job!
The teacher
should entertain all responses, but not immediately tell students the
ants’ roles. Tell the students that they will discover what these
special ants do by watching and “being” ants!
Those are
all great predictions! Now I need everyone to watch me ears on! We will
all have a chance to be ants.
|
1. Who has
an idea (prediction) of what a scout ant does?
|
1. Is like a
boy scout?

(Have the
drama set up beforehand, see attached set up sheet)
Explain to
students, once they watch you act out the scout ant drama, they will be
doing some acting as “ants”. (2nd activity-15 mins)
Present a
drama to introduce the idea that ants that find food, leave scent
trails, and are called SCOUT ANTS (1st activity-15 mins).
|
|
|
Scout
Ant Drama
(1st
activity-15 mins):
A little
girl named Kimi is sitting outside one day eating a snack. She says, “I
don’t want to eat this cracker. I’ll leave it in my lunch bag and take
a nap.” (Make Kimi
put the cracker in the bag and lay down.)
|
|
|
While Kimi
sleeps, look what is happening nearby (Make an ant
climb out of out the anthill, walk towards the bag and climb in.)
The hungry
ant finds the cracker (Break off a
piece of the cracker and hold it next to the ant’s mouth).
|
1.What do
you think the ant is doing?
2. What
did Kimi leave in the bag that the ant might want?
3. What do
you think the ant will do with the cracker?

As it
walks back to the anthill, the ant dabs the end of its body on the
ground
(Dab the abdomen of the ant on the ground) Review
the word abdomen.
(Have the ant
carry the cracker into the anthill and disappear)
|
1. Why do
you think the ant is doing that?
|
1. It is tired
It is hurt
[The
ant is leaving a smell (scent) on the ground so the other ants can find
food]
|
Look
what’s happening! Other ants are using their antennas (feelers) to
smell! (Make several
ants walk single file from the anthill to the bag, dabbing their
antennae on the ground).
They have
found the scent!
|
|
|
The ants
are following the scent trail.
|
1. What do
you think the ants will find if they follow the scent trail?

Review drama
for understanding through questions.
Allow for
free exploration. Leave the doll, paper ants, “anthill”, bag and
cracker out.
|

the scout ants tell the other ants where the crackers were?
2. What
part of the ant’s body did it use to help it find the scent(smell)?

Following
Scent Trail Drama
(2nd
activity-15 mins):
Have the
children sit with you inside the “child-sized anthill.”Pretend you
are all hungry ants!
|
1. What
kinds of foods would you like to eat as a hungry ant?
|
1. Crackers
Cookies
Bugs
[Confirm
students’ answers]
|
Explain to
students they are going to act like SCOUT ANTS.
|
1. Who can
remind me what a scout ant’s job is?
|
1.Get food
Look for food
[Look
for food, and leave a scent trail for other ants to follow]
|
As scout
ants, you need to leave a scent trail when you bring food back to the
anthill, so other ants can follow the smell. The smell comes out of the
ant’s body (abdomen).
|
|
|
Pass around
one of the scented cotton balls for the children to smell. “This is
the special smell of ALL the ants that live in our anthill.”
|
1. What
does the cotton ball smell like to you?
|
1.Sweet
Candy
[The
actual scent will depend on what extract you used]
|
We are all
going to take turns being scout ants! You will follow a trail to food,
and will leave your special scent on the trail.
Show the
children how to leave a scent trail by following the string trail to
the paper bag full of crackers. Take a cracker out of the bag, and
carry it back to the “anthill”, while dabbing your cotton ball on the
string.
|
1. What am
I making by dabbing my cotton ball on the string?
|
1.A trail
A path
A smell
[Scent
trail]
|
Place your
cracker on the tray. Tell the children you are pretending the tray is a
special room in the anthill called a CHAMBER (where ants store their
food).
|
1. Why do
you think ants put food in chambers?
|
1. To keep it
safe
To share
[To
store/keep it]
|
Each “ant”
in our class will now take a turn, one by one, bringing a cracker back
to the “anthill” and storing it in the CHAMBER. When we all finish the
ants will eat the crackers.
|
|
|
Give each
child a scented cotton ball. Have each child take a turn dabbing scent
on the trail while bringing a cracker back to the anthill to place on
the tray (CHAMBER).Children should crawl on the ground, holding a
cotton ball in one hand and the cracker in the other. Once each child
has had a turn, the whole class can share the crackers.
Observe the
children as they act out the role of a scout ant, to see if they
understand what it means to leave/follow a scent trail.
|
1. Why are
we dabbing our scent on the trail?
2. If we
didn’t leave a scent trail what might happen?
|
1. To make it
smell
To find food
[So
other ants can follow the smell and find food]
2. It
wouldn’t smell
Wouldn’t find
food
[The
other ants would not have a scent trail to follow to find the
crackers/food]

when we acted out scout ants, this will help you with your drawing!
(Review the
words on the handout, and encourage students to cross each one off
after they have drawn each item)
(Older
students can accompany their picture with a story and label the items
in their picture)
.Ask
students to share their drawings and talk about their picture.
Drawings can
be complied into a class “SCOUT ANT” book.
