1. APPLICATION Engineering Design Process Define the Problem Research and Explore – Research issues you’ll need to understand to solve the problem. List these research items and where you’ll find information. – Explore ideas - Brainstorm multiple solutions Choose the Best Solution Specify Criteria (requirements) and Constraints (limits) **The criteria will be given to you

2. Example: You decide you want to build your dock right in front of a public park, and the waterway has endangered salmon in it. What are some of the constraints (other than cost and time) that may affect your project? Phrase it: “__________________ would be a constraint. This is a limitation on the project because____________.”Constraints

3. Engineering Design Process Build a Model Test Evaluate Success, Trade-offs and Unintended Consequences, – evaluate success: Was your design successful in meeting the criteria given the limits? – Example: “The car passengers survived even though the car crashed. The air bags and crumple-zone bumper worked!” – Trade-offs: something acceptable but not ideal – Example: “The car passengers are very bruised from the air bags but they lived!” – Unintended consequences: a situation you did not anticipate resulting from your design/solution – Example: “Cars must be sent to the junk yard once all safety features have been activated.” Redesign to optimize

5. Bioaccumulation is defined as the increase in concentration of a substance(s) in an organism or a part of that organism Biomagnification is simply the increase in concentration of a substance in a food chain, not an organism
