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

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
Short Answer Using the Design Process. Read the passage below to answer Questions 16–21. Some students are finding 7th grade a challenging year academically. The teachers have noticed that students spend too much time at their lockers looking for what they need, and as a result, they are coming to class late and unprepared—without their homework, calculator, or writing utensils. The teachers recommended that better organizational skills would help them be more successful. You have decided to team up with a couple of your classmates to design a locker organizer for your lockers. You will work together to solve the issues you find and develop a new organizer that will be innovative and allow students to maximize the organization and cleanliness of their lockers.
Based on the scenario above, write a problem statement that accurately defines the problem that the team of students is working to solve.
List four possible criteria and constraints your team will consider as you write your problem statement.
Based on your problem statement, describe two types of information you would conduct research on to solve this problem.
Explain two tasks that your team could complete as they generate concepts for the solution.
Students designed, created, and tested their prototype made from fabric and found that when the organizer pockets were full, the fabric would fold in due to the weight. Describe what the team should do next. Give a specific example.
Describe two types of data that would be important to collect to determine the success of your locker organizer.
