Total questions: 20
Worksheet time: 26mins
A design team is working on creating a new energy-efficient light. They have completed the following steps: - They asked questions, did research, and determined the design requirements for their solution. - They brainstormed, sketched their ideas, compared them, and identified the best possible solution to pursue. - They created detailed technical drawings, including CAD drawings, to use to produce their solution. What is the next step of the design process that they should complete?
Develop and Test Solution
Present the Solution
Evaluate Solution
Design a Solution
Which of the following behaviors can negatively impact team success?
Group members listen to each other and everyone’s ideas are heard
Group members feel free to disagree, but all feedback given is helpful
Group members focus on the ideas of those with the best grades in the class.
Group members understand their tasks and help each other achieve the goals
Which of the following best describes why sketching is an effective communication tool?
Designers can color parts of a sketch to show texture and communicate an object’s appearance
Sketching allows designers to accurately communicate details of their ideas with lots of information at once
Using sketches to communicate ideas makes the design neat and pleasing to the eye
Sketching tells a story about the design, such as how it might be used or where it will be made
Which sketch might a designer or engineer use to communicate their design with dimensions?
A perspective sketch
A multiview sketch
An isometric sketch
A thumbnail sketch

Why is a decision matrix an important tool to use in the design process?
A decision matrix is used to identify the criteria, constraints, and deliverables
A decision matrix organizes your sketches, models, and brainstorming
A decision matrix determines the best solution by comparing design ideas to the criteria and constraints
A decision matrix is a contract between the client and the designer
Engineers, scientists, and designers innovate products by taking apart existing products and observing and documenting how they work, to determine how they can be improved. What is this process called?
Statistical analysis
Mechanical dissection
Mathematical modeling
Use the images below to answer the question. From this multiview sketch, what is the volume of this rectangular prism? Use the formula: V = l x w x h
46 in.²

Students in a physical education class ran one mile. Each student’s time is recorded in the table. What is the mean time in minutes of all the students’ times?
4.728 minutes
591 minutes
5.91 minutes
9.85 minutes
Students in a physical education class ran one mile. Each student's time is recorded in the table. What is the median time in seconds of all the students’ times?
598 seconds
591 seconds
605 seconds
108 seconds
The physical education teacher made these box-and-whiskers plots from the one-mile run data for two classes. The goal is for every student to complete the run in less than 9 minutes and 30 seconds. Based on the graph, which of the following statements is true?
Class B has the fastest runner
The median time of Class B is faster than the median time for Class A
Both classes have students who have not met the time goal
All of the students in class B met the one-mile run goal
While there are different versions of the design process, what is important in any type of design process?
The design process is linear, and each step must be completed in order and cannot be repeated
The design process must be iterative where designers can revisit previous steps to modify and change their design based on failures and testing
The design process must include steps for brainstorming and developing a design solution, but does not need to include design testing
The design process requires designers to return to the very first step each time the solution fails design testing
This step in Design process includes researching past solutions and brainstorming possible new solutions. You come up with lots of ideas and then pick one.
generate concepts
develop solution
define the problem
present solution
evaluate solution
After building a paper airplane, you throw it and it immediately crashes. You realize that there is a major flaw in your design. What should be the next step?
destroy the old airplane and start from scratch
change the design and test it again
use a different color paper
A technology company has identified the need for a smaller laptop computer that weighs less, but they do not have enough knowledge about how to build it.
What would be the next logical step engineers would take to design and produce this laptop computer?
Build a new type of laptop battery
Research current laptop technology
Build a prototype computer
Engineers plan on developing a new drill for use on oil rigs. What should the engineers do first in order to develop the new drill?
Find out features the drill will need by asking questions
Determine the materials needed to build the new drill
Build a prototype of the new drill
