Essential Question(s)
Describe all the steps of the process by which technology products are designed, built, tested, and produced.
Check for Understanding
Apply the engineering design process to construct a
prototype that meets given specifications.

2. Engineering Design Process (EDP)
EDP is used to develop technology products and/or solutions.
…is different from the scientific method, but uses the same tools

5. Engineering Design Process
Early Phone Prototype
"Mark 1 Version"
(EDP Step 1)
Identify and Research A Need
What need did this technology address?
Was it a "life or death" need?
(EDP Step 2)
Develop possible solutions
What are some other ways they could have addressed the need for communication?
(EDP Step 3)
Build a prototype
What materials did they use when constructing these early phones?

Billionaire genius and weapons designer Tony Stark is captured by terrorists, and they want him to build a super-weapon.
Instead he builds an armored exoskeleton to fight them.
1st Prototype
Mark 1 Version
3rd Prototype
Mark 3 Version

11. Prototypes are often called mark versions

12. Engineering Design Process
SPI 0807.T/E.2
Engineering Design Process
Step 1: Identify a need
Why did Tony Stark build the "Iron Man" suit?
Step 1A: Do Research about the technology
Did Tony do any research first?
Step 2: Develop Possible Solutions
What are some other options he could have built instead?
Step 2A: Pick the best design
Do you think the "Iron Man" suit was the best design?
Step 3: Make a prototype
Where and how did Tony build his prototype(s)
Step 4: Test the prototype
Where and how did Tony test his prototype(s)
Step 5: Modify and re-test the prototype
How did Tony modify his prototype to make it work better?
Step 5A: Use and/or sell the product
Did he use or sell his Iron Man armor?
How did he use it?

13. -From the “Ironman” movies
EDP in the Movies
-From the “Ironman” movies
Step 5: Modify and re-test the prototype
With his mark-1 prototype, Tony realized that he needed to design a way to don his armor more quickly.
He improved the process with his mark-3 prototype.

He later designed a mark-5 “suitcase” prototype.
Video Link (28 sec): Mark-5 Suitcase Armor
