Context and Purpose
The Context
Puppets and puppet performances have universal
appeal and play an important role in story telling
traditions in some cultures, and in bringing
stories and poems to life.
In this unit students will design and make lever-
operated puppets that can be used to promote an
interest in animals and their movements. At the
end of the unit, each student will have a model
puppet with movable body parts. The students
(in small groups) can create or recreate a familiar
puppet play to present to younger students in the
school.
The Purpose
In this unit students will learn:
how to observe and imitate animal
movements;
how to sketch animal shapes;
about simple levers;
about linkages;
how to scale up (make things bigger);
how to mark, measure, cut and join materials
with increasing accuracy;
how to use a variety of tools with precision
and care;
how to produce decorative effects on
cardboard.

Making Decisions
Design Decisions
Students will decide on the following:
the characteristics of the animal: this
introduces deciding which savannah animal
is to be modelled;
which body part will move;
the appearance: the surface decoration
of the puppet with careful observation of
photographs of animals in their natural
habitat;
if there will be multiple movements from the
puppet;
construction methods: deciding on the
method of construction by thinking about the
arrangement of levers, how and where to join
them;
what scaling-up method to use.

Looking at Values
Grades 1 - 3
Making design decisions involves making value
judgements. Making these judgements is an ongoing
process that will permeate this unit. Teachers should
engage students in thoughtful discussion that will
help them make decisions that are important to
themselves and eventually to society.
Values are influenced by personal priorities. This
is particularly relevant in the case of Grade 1 - 3
students. Teachers should explore how students
feel and what they think, knowing their experience
is centred on themselves, their friends and their
family. Discuss how these relationships might
influence them when making decisions.
Teacher input
Explain to students that products and services are
designed and made to meet a need or want. Tell
students that when they decide about the worth
or importance of a product, they are making a
value judgement about its quality. Tell students
that a democratic society requires each student to
become an informed citizen who will use his or her
knowledge and value system when making decisions
about technology in settings outside the school.
Explain to students that as they learn to recognize
and discuss values, they will begin to compare
how their own values are similar to or distinct
from those of friends and others. Ask questions
that will help students conceptualize what values
are and how these values might impact their
life, both now and in the future. Recognize that
students’ answers will reveal value judgements
that become more complex and sophisticated
with practice and experience.
At appropriate times throughout the unit, use the
following questions as starting points to engage
students in thinking about and discussing values.
Aesthetic values
In what ways is the product pleasing to the
senses?
Do I like my product? If so, why? If not, why
not?
Technical values
What materials were used in the production?
What skills were needed to make the product?
Does the product perform its intended
function?
Will the product withstand extended use?
Economic values
Who else would want to own the product?
Why would someone else want to own the
product?
Environmental values
How long will the product last?
What happens to the product when it is no
longer wanted?
Social values
Whose needs or wants were considered
during the designing?
What needs or wants were considered during
the designing?
Moral values
How does the product affect me?

Support Task 1: Who are the African savannah animals?
40 minutes
Student activity
Show the students a world map and identify the
various continents. Explain the term “savannah”
to the students. Using a small square of
construction paper, label the African savannah
on a world map for the students. Discuss the
vegetation, climate and weather of the savannah
with the students. Ask the students, “what type
of animals do you think could live in such a
habitat?”
Read a story (e.g., One Small
Square – African Savannah by
Donald M. Silver or The Lion King)
to the students or another chosen
book on the savannah. Ask the
students to think about all of the
animals mentioned or illustrated
in the book. On chart paper, list
all of the savannah animals
that the students can
identify after listening to
the story.
Teacher input
Tell the students that they are going to design
and make a collection of attractive, intriguing
savannah animal puppets that have movable
body parts which can be used for small group
puppet plays. Explain that to design and make
a lever-operated puppet, they will need to know
about levers and savannah animals. Today they
will learn what animals live in the savannah.

Support Task 2: Exploring animal movements
40 minutes
Teacher input
Tell the students that the animal they will design

Have the students model animal movements.
Develop with the class a list of words to describe
animal movements/posture (hunched, stretching,
striding, leaping, hopping etc.)
Student activity
Show the students a video clip from a movie, for
example, The Lion King, to illustrate the savannah
theme. Tell the students to watch the different
animal movements carefully. Ask students to
identify different savannah animals and their
movements.
Have students mime the characteristic movement
of one of the animals from the video clips or from
the list. The class guesses what animal is being
imitated. This game can continue until most
of the animals have been mimed or until each
student has had a turn.
Students can make a flip book using the BLM
“Flip Book” to show horse movements.

Support Task 3: Exploring levers
40 minutes
Teacher input
Tell students that every day we use machines to
help us do work. Examples include machines to
dig trenches for underground pipes, machines to
produce food in factories, a pair of scissors to cut
fabric, and a lawnmower to cut the grass. Next tell
the students that not all machines are large and
complex. A knife, a bottle opener and a hammer
are all machines. Many machines are quite simple.
A common example of this is a lever.
Student activity
On a large picture of a teeter-totter label the
fulcrum, the effort, and the load. Next label the
fulcrum, the effort and the load on a picture of a
person using a garden rake. Ask students for their
definition of the fulcrum, the effort and the load.
Through discussion derive appropriate definitions.
Write these on chart paper and leave prominently
displayed for the remainder of the unit.
Show sample levers to the students. Examples
might include scissors, wheelbarrow, baseball bat,
garden rake and utility dolly. Have them label the
fulcrum, load and effort on these sample levers.
At the end of this Support Task ask students to
bring to the next class examples of levers they use
in their home.

Support Task 4: Levers all around us
40 minutes
Teacher input
Have the students display the levers brought from
home so they can be examined by the class. Tell
the students that there are three types of lever
and that today they are going to learn how to
differentiate between them.
Student activity
Give each student an example of a lever. Tell each
student to write the words fulcrum, load and effort
on three different sticky notes and place them in
the appropriate place. Have the students explain
to the class why they labelled as they did their
choice of the fulcrum, load and effort positions.
Refer students back to the definitions posted at
the front of the classroom.
Place three large tubs at the front of the classroom
labelled Class 1 levers, Class 2 levers, and Class 3
levers. Ask students to sort these levers now they
have labelled them. What is the pattern? Explain
to the students that there are three classes of
lever. Refer back to Support Task 3 when it was
discovered that the fulcrum, load and effort are
not always in the same order. Describe the three
classes of lever to the students (class 1: EFL, class
2: FLE, class 3: FEL), referring to the diagrams
that are displayed above three tubs at the front of
the class. Have the students place their levers in
the tubs below the appropriate class of lever (class
1, 2 or 3). Leave these on display for the remainder
of the Support Tasks and during the design and

Support Task 5: Link it up
60 minutes
Teacher input
Tell the students that they will need to make one or
more parts of their savannah animals move. To do
this they must use two levers to create a linkage.
They must know how the location of the fulcrum
affects the movement of an output lever. In today’s
lesson they are going to learn this by making a
moving giraffe’s head. The BLM “Giraffe body
and head outline” is provided as a pattern. The
teacher will need to pre-cut a sufficient number of
heads and bodies from corrugated cardboard.
Student activity
Show the class how to punch a hole in a popsicle
stick using a heavy-duty punch and how to punch
a hole in corrugated card. (The teacher may have
to pre-punch a number of popsicle sticks for use
by students who find this too difficult.) Show
the class how to use paper fasteners to make the
fulcrum. Divide the class into three groups. Give
each group an illustration to show the fulcrum
locations and have each group construct a giraffe
with a moving head. The students can decorate
their giraffe head using a variety of materials,
including markers, crayons, sticky labels, and
construction paper.

making your lever puppet?
Which is the input lever?
Which is the output lever?

Support Task 6: Scaling up: Making things come to life
Teacher input
Explain to the class that as they are going to design
and make a large savannah animal they may find
they need to scale up small design drawings.
There are three ways to do this. One way is to
use a grid (available as the BLM “Drawing things
bigger – blank grid”). Another way is to use the
overhead projector. A third way is to scale up
mentally and then transfer the mental image onto
paper.
Give each student a small line drawing of an
animal (there are eight animals to choose from on
BLM “Drawing things bigger”).
Give each student a piece of blank paper and
show them how to draw a grid that has the same
number of vertical and horizontal lines as on
the small picture. Have some prepared grids for
students who may find this difficult (available as
the BLM “Drawing things bigger - blank grid”).
Demonstrate how to use the small line drawing
plus grid to transfer the drawing onto the large
grid.
Show the students how to use the overhead
projector to scale up a small drawing. Finally
show students how to look at a picture, mentally
make it bigger and then draw it on paper at a
larger scale.
Student activity
Each student uses the three techniques to produce
large-scale drawings which can be put on display
for future reference.
Students come back together for a large group
discussion.
Which method did you find the easiest and
why?
Which method did you find the most
challenging and why?
Which method do you think you will want to
use to create your savannah puppet?

Support Task 7: Tool time: Puzzle time
Teacher input
Tell the students that when they make their
savannah animals it will be important that
they are able to mark, cut and shape materials
accurately and safely. In this lesson they are
going to learn how to do this by making a jigsaw
puzzle.
Have students use the large face of a cereal box.
Show them how to make one straight cut using
a safety ruler, utility knife, and cutting mat
(to protect the table top). Making one cut will
produce two pieces of a puzzle. Show the students
how to make a single cut on each of the two pieces.
Now there are four pieces. Tell s t udent s
this process can be repeated
several times.
Student activity
Tell the students to choose the large face of a
box with a picture and use this to make a jigsaw
puzzle. They can decide on the number and
location of the cuts. Some students may want to
plan the number of pieces (on a piece of paper
the same size as the picture) before they begin
to make the cuts. Utility snips can be used to cut
curved lines in cardboard.
Relating this Support Task to the Big Task
At the conclusion of this Support Task have
students tell you what they have learned about
marking and measuring using tools. Next ask

Support Task 8: Boastful badges
Teacher input
Tell students that when they have produced the
body of their savannah animal puppet and then
designed and made the linkage they will have to
decorate it in some way. They are going to learn a
variety of techniques by making a badge that will
attract someone’s attention.
Student activity
Give the students a pre-cut circle of cardboard
for the badge. Show the students examples of
different colours (some shiny, some matte), lines
(straight, jagged, zigzag), and textures. Show
a selection of decorative colours and patterns
on camouflaged animals, textures on a variety
of fabrics (smooth, furry, rough), and edge
treatments using specialty scissors.
Show the students how to use felt tip markers and
how to stick on coloured paper or found materials.
Show the students how to fix a badge clip to the
back of the badge.

The Big Task: Designing and making a lever-operated puppet
Teacher input
Tell the students that they are now going to design
and make a lever-operated puppet for a play on
the theme of African savannah animals. Each
student will need to make the following design
decisions:
Which savannah animal is to be chosen?
How big to make the puppet (this is likely a
class decision since all the animals must be in
proportion to one another).
Which scaling-up method to use.
Which part(s) of the animal do I want to
move?
What will the linkage look like?
How will I decorate my puppet?
Students should complete the BLM “Lever-
operated puppets: My design decisions.”
Once each student has decided on the animal
and its size it is important that they draw the
animal on paper before drawing it on cardboard.
Some students may find this difficult to do from
memory, so they can refer to books. When they
find a picture they like they can carefully trace
the outline of the animal. Once the student has a
small-scale drawing they must choose a method
of scaling-up to the size chosen by the class
(50 cm x 50 cm is a workable limit). The learning
from Support Task 6 will be used to do this.
Before the students trace the scaled-up drawing
of their animal onto card they should think about
which piece they want to move and try to plan
where the levers will be placed and particularly
where the fulcrum will sit. Some students may
find this too difficult to do in sketch form, and
should be allowed to experiment with three-
dimensional materials, for example with strips of
card to represent the levers.
Do not insist that students have worked out all the
operational issues before they begin to make their
animal and its linkage. The learning from Support
Task 5 will help students with this.
Students can cut out the shape of their animal
with scissors and either hold it or tape it in place
while tracing the shape, gluing it to the cardboard,
or by holding the outline onto card. The learning
from Support Task 7 will help students mark
and cut accurately. Some students may create
additional problems because the part they want
to move is narrow and floppy. They can tape extra
thicknesses of card to make the piece more rigid.
Students can then experiment with the placement
of the levers and fulcrum until they create the
type of movement they want.
The students will want to decorate their puppets
and learning from Support Task 8 will help them
be successful here.

Specific expectations: Understanding basic concepts 1 2 3 4 5 6 7 8 BT describe, using their observations, ways in which the strength of different
materials can be altered (e.g., folding increases the strength of paper)
describe ways in which forces alter the shape or strength of different structures (e.g., a load may cause a cardboard box to buckle)
describe ways to improve the strength and stability of a frame structure (e.g., use of triangulation or a cross-member)
describe, using their observations, the role of struts (e.g., to resist compression) and ties (e.g., to resist tension) in structures under load (e.g., describe the effect of adding a strut to a wooden frame)
describe, using their observations, the changes in the amount of effort needed to lift a specific load with a lever when the position of the fulcrum is changed
describe, using their observations, how simple levers amplify or reduce movement (e.g., in operating the limbs of a puppet)
describe the effects of different forces on specific structures and mechanisms (e.g., a structure collapses when the load is too heavy; a latch on a gate opens when pressed)
Specific expectations: Developing skills of inquiry, design, & communication 1 2 3 4 5 6 7 8 BT ask questions about and identify needs and problems related to structures and
mechanisms in their immediate environment, and explore possible answers and solutions (e.g., investigate the effects of folding on the shape and strength of materials)
plan investigations to answer some of these questions or solve some of these problems, and explain the steps involved
use appropriate vocabulary to describe their investigations, explorations and observations (e.g., use terms such as fulcrum, load and effort when describing levers)
record relevant observations, findings and measurements, using written language, drawings, charts and graphs (e.g., record the modifications they have made to increase the stability and strength of their structures)
communicate the procedures and results of investigations for specific purposes and to specific audiences, using demonstrations, drawings, simple media works and oral and written descriptions (e.g., make a mobile that illustrates their discoveries about balance)

Specific expectations: Developing skills of inquiry, design, & communication 1 2 3 4 5 6 7 8 BT design and make a stable structure that will support a given mass and perform
a specific function (e.g., a bridge, a photo frame)
use appropriate materials to strengthen and stabilize structures that they have designed and made and that are intended to support a load (e.g., use gussets, struts, ties, buttresses)
design and make a levered mechanism (e.g., a model of an animal whose legs are moved with a lever)
design and make a stable structure that contains a mechanism and performs a function that meets a specific need (e.g., a drawbridge, a crane)
use appropriate equipment and adhesives when making structures that they have designed themselves (e.g., transparent tape for paper; low-temperature glue gun for wood)
use hand tools (e.g., hand saws, scissors) and equipment (e.g., templates, mitre boxes) appropriately to cut a variety of materials (e.g., wood, paper, cardboard, plastic)
Specific expectations: Relating science and technology to the world outside the school 1 2 3 4 5 6 7 8 BT distinguish between the structure of an object (e.g., the chassis of a vehicle)
and its mechanical parts (e.g., the wheels and axles)
recognize that geometrical patterns in a structure contribute to the strength and stability of that structure (e.g., a climbing frame)
demonstrate awareness that the strength in structures is due to bulk (or mass), number of layers (e.g., layers in particle board) and shape (e.g., triangulation)
identify a number of common levers (e.g., crowbars, scissors, hammers, pliers, wheelbarrows, tweezers, tongs) and describe how they make work easier
identify efficient ways of joining the components of a mechanical structure or system (e.g., construct a right-angled corner; use an axle at a right-angle to the frame)
describe, using their observations, how different balance points of different masses affect the stability of a structure
predict which body positions provide the most stability in various circumstances (e.g., standing with legs apart; lying on the ground)
