Part 1: Order the Eight Steps of the Engineering Design Process

We are given a list of steps (A–H) and need to number them in the correct order from 1st to 8th.

Here are the steps:

- A. Test and evaluate the solution(s)
- B. Construct a prototype
- C. Research the problem
- D. Identify the need or problem
- E. Select the best possible solution(s)
- F. Redesign
- G. Communicate the solution(s)
- H. Develop possible solutions

Now, let’s recall the standard Engineering Design Process steps in order:

1. Identify the need or problem
2. Research the problem
3. Develop possible solutions
4. Select the best possible solution(s)
5. Construct a prototype
6. Test and evaluate the solution(s)
7. Redesign (if needed)
8. Communicate the solution(s)

So now match them:

| Number | Step |
|--------|------|
| 7. | D – Identify the need or problem → 1st step |
| 8. | C – Research the problem → 2nd step |
| 9. | H – Develop possible solutions → 3rd step |
| 10. | E – Select the best possible solution(s) → 4th step |
| 11. | B – Construct a prototype → 5th step |
| 12. | A – Test and evaluate the solution(s) → 6th step |
| 13. | F – Redesign → 7th step |
| 14. | G – Communicate the solution(s) → 8th step |

✔ So the answers are:

- 7. D
- 8. C
- 9. H
- 10. E
- 11. B
- 12. A
- 13. F
- 14. G

Short Answer Questions

#### 15. An ice-cream company decides to make a new lower calorie flavor, but testers reported that the flavor wasn't as good as the original. Is this an example of trade-off? Explain why or why-not.

Answer:
Yes, this is an example of a trade-off. The company chose to reduce calories, which is a health benefit, but as a result, the flavor quality decreased. This means they had to give up some taste to gain a healthier product. Trade-offs involve sacrificing one feature or benefit to gain another.

#### 16. A cookie company decides to develop a new chocolate chip cookie. They decide to test three different recipes at once. What are the advantages of making more than one prototype at a time?

Answer:
Making more than one prototype at a time allows the company to compare different designs or ingredients side by side. This helps them identify which recipe performs best in terms of taste, texture, and appearance faster. It also saves time and resources by testing multiple options simultaneously instead of one at a time.

#### 17. What are three reasons why you should make your first prototype on a smaller scale?

Answer:
1. It is less expensive to build and test a small-scale prototype.
2. It is quicker to construct and modify, allowing for faster feedback and improvements.
3. It reduces risk—any flaws or failures won’t waste large amounts of materials or time.

#### 18. What is an example of a trade-off that a car company might make?

Answer:
A car company might choose to make a car more fuel-efficient by using lighter materials, but this could mean the car is less safe in a crash. This is a trade-off between fuel efficiency and safety.

Matching Steps:

7. D
8. C
9. H
10. E
11. B
12. A
13. F
14. G

Short Answers:

15. Yes, this is a trade-off because reducing calories improved health but reduced flavor quality.
16. Testing multiple prototypes at once allows comparison, faster results, and better decision-making.
17. Smaller scale prototypes save money, time, and reduce risk.
18. A car company might trade off safety for fuel efficiency by using lighter materials.
