Unit 1 Lesson 2

Defining a problem is often the first part of an engineering design process. Which of these steps are usually part of defining the problem? Select all that apply.

• evaluating the design

• finding a problem to be solved

• doing additional research

• brainstorming

• testing a solution

Good __________ techniques include thinking of all possible ways to solve a problem

• brainstorming

• deforesting

• erosion

• criteria

After brainstorming, the best thing to do is _______________

the list in order to figure out the best way to solve the problem.

• expand

• narrow

Which of the following are true about the engineering design process? Select all that apply.

• Collaboration and communication never play a role in the design process.

• Each step needs to be followed in an exact order.

• Sometimes steps are repeated or blend together.

• Some solutions work better than others.

• The steps are always the same, no matter what the problem.

After a ____________has been identified, it is important to do research to learn as much as possible.

• problem
