Engineering Design Process

What is the FIRST Step in The Engineering Design Process?

• Define the problem.

• Identify constraints on your solution.

• Brainstorm solutions for the problem.

• Communicate your results.

Once you define the problem and identify constraints and needs for success, you must...

• Define the Problem.

• Determine which solution will be the best.

• Brainstorm multiple solutions.

• Brainstorm 1 possible solution.

Define a "prototype".

• A PROTOTYPE is the problem you have discovered.

• A PROTOTYPE is the conclusion you reach at the end of the Engineering Design Process.

• A PROTOTYPE is a test to determine if your solution works.

• A PROTOTYPE is the first sample created to test your solution.

A group of students are designing a solar cooker. As part of the design process, the students must test a prototype to see if it is able to boil water. What should the students do just before they test it?

• Test and evaluate the prototype.

• Imagine possible solutions.

• Change the prototype and retest it.

• Plan and make a prototype.

• Identify and research a need.

A group of students is designing a solar cooker. What should the students do right after they test and evaluate their solar cooker?

• Test and evaluate the prototype.

• Imagine possible solutions.

• Change the prototype and retest it (iterate).

• Plan and make a prototype.

• Identify and research a need.

An engineer has just finished building a prototype of a lawn tractor that is powered by the sun. Which of the following should be the next step in the design process?

• Test the prototype and evaluate its performance.

• Ask for the funding to build more copies of the prototype.

• Build a second prototype that is different from the first.

• Make changes to the prototype that will increase its performance.
