Quiz: What Is the Design Process? HMH U1 L2

How are models used in the engineering design process?

• Models are lists of needs to be addressed.

• Models are things that can be tested for efficiency.

• Models are the final products sold to consumers.

• Models are tables of data that can be sorted and analyzed.

Tomas notices that his tomato plants wither when they are in high temperature and direct sunlight during the summer. He decides to use the engineering design process to make a sunshade for his tomato plants. How can Tomas test his solution?

• record the average daily temperature in the area

• conduct research about tomato plants and weather

• compare plants without a sunshade with plants with a sunshade

• measure the amount of water required by tomato plants without sunshades

Which procedure could be used to predict design flaws in a fabric used to make sails for ships?

• analyzing the deck of the ship for strength

• testing to see how much weight the ship can carry

• marketing the sails and recording customer complaints

• stressing the fabric with wind and weather over a period of time

Maria tested a prototype to organize things on her shelves and keep them from falling. When she tested her prototype, she found there was not enough room on her shelves for all the items she wanted to place there. What is the best approach for Maria when she redesigns the prototype?

• add new criteria

• use the same criteria

• change all the criteria

• get rid of the old criteria

Engineers test four dishwashers, models A through D. The engineers discover that dishwasher model B does not clean the dishes well. Which is the next step for the engineers?

• Make and sell the model B dishwasher anyway.

• Start all over with a brand new design for a dishwasher.

• Evaluate what is wrong with model B and work to redesign it.

• Choose a different appliance to make and sell instead of dishwashers.
