1.2 Vocabulary

What is engineering?

• designing a controlled experiment

• designing and building a solution to a problem

• reviewing and critiquing a scientist's research

• asking questions about the natural world

What should you consider when choosing the best solution?

• the practicality of the solution

• the cost of the solution

• the benefits and risks of the solution

• all of the above

What is a problem?

• a difficulty or need

• a type of solution

• a testable question

• a mathematical equation

What should you do after you define a problem to better understand what the problem actually is?

• Ask testable questions.

• Perform a controlled experiment.

• Research the problem.

• Conduct a survey.

What should you first do when brainstorming?

• come up with many solutions, even if they seem crazy, that could solve the problem

• focus on the most effective solutions that could solve the problem

• disregard the craziest solutions that could solve the problem

• identify the who, what, and why of the problem statement

the best possible solution should :

• be expensive and high tech

• balance effectiveness with practicality

• be effective but expensive

• be practical but expensive

What does it mean to prioritize criteria?

• make sure your solution addressed the most important needs associated with the problem

• making sure your solution is inexpensive

• testing your solution over and over again

• developing tools that will help you build a prototype

a model can be:

• a three-dimensional structure

• a diagram or drawing

• a mathematical equation

• all of the above

What is an engineer?

• a scientist who creates problems

• a scientist who designs and develops solutions to problems

• a scientist who performs controlled investigations

• a scientist who critiques the innovations and designs of others

What does it mean to brainstorm solution to a problem?

• think of ways to make the problem worse

• think of ways to make similar kinds of problems

• think of ways to solve the problem

• think of ways to observe the problem
