CSE 1st Nine Weeks Assessment

A company is making prototypes for a new computer system. Which of the following statements best describes an advantage of making several different prototypes?

• Testing simultaneously

• Purchasing by many users

• Producing in large quantities

A manufacturer has developed a textured surface for plastic cups and produced prototypes. What is the next step in the engineering design process?

• Market the new textured cups

• Redesign the textured surface

• Test and evaluate the prototypes

An engineer suggests using a robotic system to manufacture a particular chemical. Which of the following is most likely the engineer’s reason for making the suggestion?

• Reducing the cost of materials

• Reducing workers' exposure to chemicals

• Increasing the cost of production

Sarah presented an idea for recycling used tires to an automotive company. If she followed the engineering design process, what was the first step in developing her idea?

• Identifying a problem to solve

• Selecting the best solution

• Building a prototype

Juan is planning to design a kite. After conducting research, he creates several different designs and selects the one he wants to use. What should be the next two steps in Juan's design process?

• Build a prototype and test it

• Construct and finish full-sized kites

• Patent the design and sell it

If your initial design doesn't fully solve the problem, which step corrects this?

• Improve
• Imagine
• Plan
• Create

Scenario: Students want to sell cold drinks to raise funds for a field trip. They need to keep the drinks cold for 3 hours at the ball game. At which step of the engineering design process are the students?

• ASK

• IMAGINE

• PLAN

• CREATE

Scenario: Johnny came up with an idea to make a solar oven for a science project at school. According to the Engineering Design Process, what should be Johnny's next step?

• Make a plan and draw a diagram.

• Research designs and imagine possible solutions.

• Create a prototype.

• Test the design.

Engineers must understand the difference between requirements and constraints. Let's say a team of engineers is asked to design a pair of kids' tennis shoes for less than $20. They determine that the only way to manufacture shoes for this price is to use recycled materials. What is the team's constraint?

• The shoes must be designed for kids.

• The shoes must be made out of recycled materials.

• The shoes must cost less than $20 to manufacture.

Although the terms “model” and “prototype” are often used interchangeably, they are not the same thing. A _______ is used to test different aspects of a product before the design is finalized. A ______ is used to demonstrate or explain how a product will look or function.

• model, prototype

• prototype, model
