Bionic Arm
Project
*You and two other students will be
working together to make a bionic arm.
This machine must lift a quarter from the
floor to the height of your table. It must
work in the same way your bones and
muscles do. You may use any object(s)
found around your home. Buying
materials is not allowed!!
*As you work with your group you will be
working through the steps of the Scientific
Method and will be required to create a lab
report which will accompany your bionic
arm. As a reminder the steps of the
Scientific Method include: purpose,
research, hypothesis, experiment,
analysis, and conclusion. We will talk
more about this at a later date.
Machine Requirements:
*Your machine must have at least 3 parts:
1. One part must act like a muscle
2. One part must act like a bone
3. One part must act like a joint
*You can use human power to get the
“muscle” to move.
*Your machine only has to lift the quarter
from the floor to the height of your table—it does
not have to drop the quarter onto the desk.
Research:
• We have investigated how a muscle works to
move the bone in your body. Use the questions
below to help further your research.
• My muscles are attached to my bones with
_________. There is a _______ at my elbow.
• When I lift my forearms, the muscle in my bicep
_______. This action pulls my forearm bone up.
Create a list of items that could
contract (squeeze together) like a
muscle.
Create a list of objects that
would act like bones.
Create a list of objects that
would act like a joint.
How will your quarter stay on
the machine? Write down all of
your ideas.
