Engineering Review

1. What is the correct order of steps to follow in the engineering design process?

• report the results; identify a need; carry out research and brainstorm solutions; build and test a prototype

• New identify a need; carry out research and brainstorm solutions; build and test a prototype; report the results

• build and test a prototype; report the results; identify a need; carry out research and brainstorm solutions

• carry out research and brainstorm solutions; build and test a prototype; report the results; identify a need

Which of these best describes the brainstorming stage of the engineering design process?

• identifying a need to be addressed

• gathering feedback about prototypes

• collecting information from a variety of background sources

• using group input to discuss and prepare preliminary designs

Scientists do many types of work, including conducting experiments. Which description characterizes a scientific experiment?

• observation of plants or animals in their natural environment

•  use of physical or mathematical representation of an object or process

• collection of data from the unregulated world for comparative purpose

• conducting an organized procedure to study something under controlled conditions

Engineers have been designing a ship that can move through large ocean waves safely. After research, they decide that new criteria and constraints will improve the design of the ship. Which action will they most likely take in dealing with the new criteria and constraints?

• Build the ship according to the original plan.

• Scrap the plan and start the design process again.

• Consider the constraints only and revise the design process

• Reframe the criteria and constraints to match the additional research.

A large group of research laboratories are looking to buy science equipment. The picture shows a large glass graduated cylinder they are currently purchasing from company A. They would like to have new graduated cylinders that are lightweight and durable. They must also be much cheaper than the glass cylinders and delivered quickly. Company B is offering to design and make a new version of this cylinder, which will be made of plastic and much smaller. Which evaluation describes how well company B is meeting the laboratories’ needs?

• Company B is meeting the criteria.

• Company B is meeting the constraints

• Company B is meeting the criteria and constraints.

• Company B is meeting one criteria and one constraint.
