Unit 1 • Engineering and Technology - Lesson 3

How is communication an important part of designing solutions?

• Communication helps people talk about improvement.

• Communication helps identify problems.

• Communication only causes arguments.

• Communication builds a sense of teamwork.

• Communication is critical only if everyone agrees.

Answer explanation

• An engineering design solution might not actually work when tested. Thus, it is important to try several alternatives to improve the chances of success.

• Identifying what doesn’t work helps engineers improve a prototype.

• Communication is critical to any team because hearing others’ feedback can lead to fresh ideas.

Match the following correct words to complete each sentence

• When building and designing an engineering solution, it is always important to ____the solution.

• original problem

• Good engineers will always try to test a solution

• test

• It is important to keep in mind the _____that the solution was meant to solve

• multiple times

Answer explanation

Often, learning what doesn't work is just as important as just seeing what doesn't work in a design solution. Learning from mistakes can provide information on what not to do on future designs.

Select each correct statement.

• Making good observations is important.

• Making good observations helps to figure out what needs to be improved.

• Making good observations shows you what to test next.

• Making good observations is not important because it slows down the process.

• Making good observations can be distracting and should be stopped when it happens.

An engineer is testing a solution. The solution is failing. What should she do? Select all that apply.

• She should consider using other materials for the same design.

• She should figure out what didn’t go right with her design.

• She should understand that sometimes things don’t work as planned.

• She should not try to develop other solutions to this problem.

• Making good observations can be distracting and should be stopped when it happens.

Feedback is important in solving any problem. Select the best example of how to give good feedback Select all that apply.

• Tell the other person that his or her project is a good example of what not to do.

• Tell the person that his or her design is poorly built. Do not suggest any improvements.

• Tell the person that his or her design is built well, but still suggest some possible improvements.

• Ignore the person if he or she isn’t listening to you.

• Making good observations can be distracting and should be stopped when it happens.

Which of these describes a good approach to solving an engineering problem? Select all that apply.

• Research, revise, and repeat.

• Give up if your first solution fails so that you don’t waste any more of your time.

• Failure marks the end of the process.

• If at first you don’t succeed, try, try again.

• Making good observations can be distracting and should be stopped when it happens.
