Big Ideas
+ STEM is not just science or technology or math or
engineering. STEM is a truly integrated approach to
these studies.
+ STEM engages students and increases motivation with
project-based learning, encourages students to solve
authentic problems, and asks them to work with
others to build real solutions.
+ Students and teachers can work together as learners
to create solutions to human problems.
Goals for This Week
Engage in a STEM challenge related to Prosthetic Limbs
+ Gain a deeper understanding of the engineering
design process and key components of a STEM
Design Challenge
+ Learn math (ratios and proportions) science (physics
and biology) and technology skills that support a
solution to the STEM challenge
+ Build confidence in implementing STEM Design
Challenges and integrating math and science
Theory of Action
If teachers and students engage in
activities that promote math and science
and engineering practices and integrated
math and science activities focused on core
math and science content, then student and
teacher STEM literacy will increase.
STEM Literacy
The ability to identify and apply
concepts, content and practices from
science, technology, engineering, and
mathematics to understand and solve
challenges or answer problems that
cannot be resolved by any one
disciplinary approach alone.
- Hays Blaine Lantz, Jr., Ed.D., 2009
This is not a Silly Icebreaker,
it is an awesome way to get to know one
another and to start thinking creatively!
To get started, we will get into three groups
of 10 to 12.
“Hi, my name is ____________, I teach
___________ at ____________ school.
This is not a _________, it is a
_____________.”

An Exploration of Body Ratios
Think About Ratios
+ With your partner, measure the circumference of your
head, (at eyebrow level), the length of your shin, the
length of your forearm, your foot, and your height.
+ Record your information on the chart at the front of
the room.
+ Place a sticky dot on the poster representing your
(shin length, height).
+ Just wondering…
Think About Ratios
Thinking About Ratios
+ There are 24 cars parked in a lot that has room for 40
cars. Another lot has 56 cars parked in a lot that has
room for 80 cars. Which lot is more full?
+ DESMOS - an online graphing site
Ratio Debrief
+What Standards/ Learning Targets could be
addressed with the Body Ratio Activity?
+What skills and/or units of study does this support?

Our Focus This Week
+ Please meet Aimee Mullins.
+ What did you notice about Aimee? What did you
notice about her legs?
+ Your task will be to design a prosthetic limb for a
client that has specific requirement for the limb. You
will be asked to present the results of your work to
the large group on Friday.
+ Revisit the steps for a Design Challenge
This Is My Brother
Kris – Defining the Challenge
Thinking Tonight
+ What do you and members of your family need your
legs or arms to do?
+ What directions do your joints bend? Where does the
strength in your limbs come from?
+ Be ready to share out tomorrow.

K’nex Ping Pong Challenge
Use K’Nex to create a free standing machine
that will move a Ping Pong ball at least 5 feet.
+ Criteria & Constraints:
+ Materials: provided K’Nex
+ Moveable: free standing and be able
to move machine to the testing zone
+ Time: 20 minutes
Test & Evaluate
+ Share briefly about your group’s
design process.
+ Test your machine for the group.

Debrief – Into the Classroom
+ How did success for this design
challenge differ from yesterday’s
marshmallow challenge?
+ What skills do mini-design
challenges build to support
students in a complex challenge?
Please . . .
+ Gallery Walk
+ Disassemble your machine
+ Return and sort your K’nex back
into the containers.
+ Take a break until 10 am.
Prosthetic Limb Design
Challenge- Getting Started
Take two minutes to look at the Design Challenge
workbook.
The Challenge:
+ Design a prosthetic limb with your team of biomedical
engineers.
First Steps
+ Who is your client?
+ What do they do?

What questions, posted yesterday, can
you answer now?
Where Are We?
Star Wars Prosthetic
Refresh... WIK?
Redefine the problem
WIK:
Our objective (problem) is design a prosthetic that
accomplishes a task.

The Athlete Machine
NTK Drives Our Research!
Group Task:
Research the basic function of simple machines.
Create a simple, yet functional, poster that discusses:
+ Fundamental principles of your simple machine
+ Identify how said simple machine replicates the function
of the human body and/or prosthetic
Group has 8.13 min to research and create the short, yet
functional poster
The Human Body/Prosthetic
Simple Machine Gallery Walk
Make a claim, with a rationale, for which simple
machine you believe is most common within the
human body.
Ok… So now WIK?
WIK:
Our objective (problem) is design a prosthetic that
accomplishes a task.
The human body is a system or network of simple
machines that helps accomplish a task.
NTK:
How can we incorporate the function of a simple
machine into the design of our prosthetic that
needs to accomplish a task?
