1. (Step 5A) Use/Sell the product (Step 2A) Pick the best design (Step 1A) Do research about this technology STEP 1: Identify and Research A Need STEP 3: Make A Prototype STEP 2: Develop Possible Solutions STEP 4: Test and Evaluate STEP 5: Modify and Retest Notes SPI 0807.T/E.1 to 2 Engineering Design Process Science Engineering Design Process (In 5 Steps with 3 sub-steps)

2. Notes SPI 0807.T/E.1 (Prototype Testing) SPI 0807.T/E.2 (Eng. Des. Process) Science The Iron Man Movies and the Engineering Design Process 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. 1 st Prototype Mark 1 Version 3 rd Prototype Mark 3 Version

3. Notes SPI 0807.T/E.1 (Prototype Testing) SPI 0807.T/E.2 (Eng. Des. Process) Step 1: Identify a need  Why did Tony Stark build the "Iron Man" suit? 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 option? 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 Tony sell his Iron Man armor? How did you use it? Science

4. Questions SPI 0807.T/E.1 to 2 Engineering Design Process Science Which step of the engineering process is this? STEP 4: Test and Evaluate

5. Intended Purpose/Consequences: When a company designs a new product, they are addressing a need. (This is Step 1 of the engineering design process). This need is connected with and is essentially the same as the intended purpose. The intended purpose/benefit is what the engineers purposely include when designing some product or process. Notes SPI 0807.T/E.3 Intended Benefits and Unintended Consequences Science Example:  Cell phones -The need being addressed is communication. Likewise the intended purpose is more effective communication. What is the intended purpose/benefit? Another Example: Automotive Technology (cars and trucks)

6. Unintended consequences: …are uses or results that engineers DO NOT purposely include when designing some product or process. …these are things that WERE NOT part of the design plan. Notes SPI 0807.T/E.3 Intended Benefits and Unintended Consequences Science Example: Cell phones and Cars -One unintended consequence is wrecking your car while talking or texting while driving. Cell phones and cars were not designed to cause traffic accidents  Intended benefit -cell phones were designed for communication  Intended benefit -cars were designed for transportation
