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

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

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

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
