TRAILS STEM Summer Camp
Watch the video below…
Did you notice the problem and how they solved it?
Notice the
process is
cyclical and can
be repeated
multiple times.
Steps may also
be skipped in
repeating the
cycle in your
design process.

In the next slide, you will explore each step
in the engineering design process. Click on
a step (the bubble) to review the step and
then type a brief response to how you will
apply this step in your own design project
that we will be working on this week. Only
a couple of sentences is necessary. At the
end of this lesson, follow the instructions to
submit your answers.
Work through the
process by clicking
the next arrow below.
If you want to jump
to a particular step
just click on it, but
don’t skip steps!
State the challenge problem in your own words.
Example: How can I design a
cow
______________________________________
eat grass
that will ________________________________?
Type your answers in the boxes above and then click the next arrow below.

You should specify the design requirements (criteria).
Example: Our growth chamber must have a growing surface of 10
square feet and have a delivery volume of 3 cubic feet or less.
You should list the limits on the design due to available resources and
the environment (constraints).
Example: Our growth chamber must be accessible to astronauts
without the need for leaving the spacecraft.
Type your answer in the boxes on the next page.

Specify the design requirements (criteria) for your project.
List the limits on the design due to available resources and the
environment (constraints) . Remember the fan design video?
List on the next page your own ideas about ways to solve the
problem. Sketch them on a piece of paper and use labels and
arrows to identify parts and how they might move. These
drawings should be quick and brief. Save to share later.

List your own ideas about ways to solve
the problem.
In this step, you should develop two or three ideas
more thoroughly. Choose your favorites from
brainstorming and briefly describe them below.

You should record pros and cons of each design idea you chose in
step 4. Be prepared to share these later with the group.
Pros

Cons
Identify the design that appears to
solve the problem the best. Write a
statement that describes why you
chose the solution. This should
include some reference to the criteria
and constraints identified before.
Think about how they did this in this
Apollo 13 video clip.

You will construct a full-size or scale model based on your CAD
drawings. We will be using 3D printers to create you prototype.
Watch the video below about printing your design using 3D
printing/additive manufacturing technology.

cycle
Later you will examine and evaluate your prototypes or
designs based on the criteria and constraints. Groups may
enlist students from other groups to review the solution
and help identify changes that need to be made. Based
on criteria and constraints, teams will identify any
problems and proposed solutions.

What is the 3rd
step after
identifying
constraints and
criteria in step 2?
A. Select an idea
B. Choose an
approach
C. Brainstorm
ideas
What is the next
step after selecting
an approach in
step 6?
A. Select an idea
B. Build a
prototype
C. Refine the
design
Save this Power Point file.
Then print the slides where
you typed your responses in
the white text boxes. You
will need to insert the slide
numbers (8, 10, 12, 13, 14,
15) in the print settings area
under “Custom Range”.
