Pasta Cantilever Questions to Consider
What kind of the concept are we addressing
here? (physics? Engineering?)
What kind of process are we addressing here?
(Physics? Engineering?)
Why do we do this activity? Have you done
something similar in your classroom?

Wrap-Up Cantilever
We know this was a “design” activity, but was this “engineering”? Why? What
makes this “engineering” and not “trial and error”?
Trial and Error:
● Is focused on just finding a solution, not optimizing the solution
● Does not attempt to discover “why” something works or doesn’t work
● Needs little or no knowledge of subject area to create solution
Engineering Design Infused Lessons aim to avoid a Trial and Error Solution.

Science Classroom:
Inquiry-Based Activities
Example: Watt’s Up Lab in
Electricity Unit
Q: Have you done something like
this in your classroom?
Q: How can we change these
activities to engineering-infusion
that addresses engineering
concepts and skills?

Engineering-Infused Classroom:
Design-Centered Thinking
Example: Watt’s Up Lab -Engineering?
Q: Is engineering design design like the
process of inquiry?
Our strategy for infusing engineering.

Why Is Engineering-Infusion A Good Model?
Save time from student schedule from taking another engineering course
Total time model - infusing engineering. Do we lose physics time? What do we
gain? Does the engineering add relevance? Why is engineering now a part
of NGSS?
