Body Movement Inspired Design
Starter Activity
• You have 2 mins to
complete the worksheet.
• Cut up the bottom in the
small parts and place
them where you think
they go on the skeletal
frame.
What Are we Learning Today
What I am Looking For
• Identify some of the different
types of joints, levers and
muscles
• Identify where they are found
in the body
• Identify some products that
generate movement or the
ability to be moved.
• Understand how some
products generate movement or
the ability to be moved.
• Identify where products have
copied or simulated the same
movements in the body.
• How to generate movement
using ICT – CAD; Seri Drawplus.
• All students to complete start
activity
• All students to complete mix
and match activity
• Most students to complete
Product Poster
• Some students to complete
their body movement inspired
design product stop frame
animation on Serif Drawplus.
Re-visiting the starter activity
Who thinks they have placed
the parts in the right place?
Have a go and place them on the
large scale skeletal frame.
Joints
• A ball and socket joint: found in the
shoulder and hip. This joint allows
the greatest range of movement.
• A hinge joint: found at the elbow
and knee. The range of movement is
limited to one plane just like a door
hinge.
• A pivot joint: found in the neck. Part
of the bone fits into another ring of
bone as in take atlas and axis,
allowing rotation of the head.
Levers
•
First order levers: The pivot is between the effort and the
load. Both effort and load are in the same direction.
– An example ; where the head pivots on the atlas. The
load is the weight of the head going down. The effort is
the muscles at the back of the neck pulling down.
•
Second order levers: The pivot is at one end of the lever. The
load is in the middle of the lever. The effort is at the opposite
end of the lever to the pivot with the direction of effort
opposite the load.
– An example; stepping up onto your toes. The pivot is at
the toes. The load is that of the body going through the
middle of the foot and the effort is in the calf muscles
pulling the body upon to the toes. This is the most
effective lever as a relatively small force can move a
large weight.
•
Third order levers: The pivot and load are at opposite ends
of the lever but the effort is off-centre towards the fulcrum.
– An example; biceps curl. The load is in the hand, the
pivot is at the elbow and the biceps make the effort.

Muscles
• Cardiac muscle or Heart Muscle is
specialised muscle that contracts
constantly and automatically.
Some factors can affect the speed
of the contractions such as exercise
and the release of hormones such
as adrenaline.
• Skeletal muscle are the ones that
can easily be seen as a shape
under the skin. Unlike smooth
muscle or cardiac muscle, we can
control skeletal muscles and
because of this it is sometimes
known as voluntary muscle.
Activities
• Complete the mix and
match activity worksheet.
Use the handling
collection to help you
understand what joints,
levers and muscles are
used.
• In your group on your
table, complete the
product poster. Identify
what joints, levers and
muscles are being used.
Don’t worry of you make a
mistake it wipe-able.
Make sure everyone in
your group inputs.
Now I want you to go make
animation of a product from the
poster.
Use Serif Drawplus – stopframe
animation to show how the specific
joint, lever or muscles enables it to
move.
