Two student pages on the engineering design process, including matching exercises and real-world application scenarios.

Let's solve both pages of this Engineering Design Process worksheet step by step and provide clear explanations.

---

✔ Page 1: Match the Word with Its Definition

We are given six terms and five definitions (A–E). We need to match each term with its correct definition.

#### Matching:

1. Engineer → E: A person who designs, builds, or maintains engines, machines, or public works
✔️ This is the standard definition of an engineer.

2. Constraint → A: a limitation or restriction that the design must consider (such as cost, time, etc.)
✔️ Constraints are limits like budget, materials, or time.

3. Troubleshoot → D: a problem-solving method used to identify the cause of a malfunction in a technological system. AKA: A way of finding out why something does not work so that it can be fixed.
✔️ Troubleshooting is about diagnosing problems.

4. Prototype → C: a working model used to test a design concept by making actual observations and necessary adjustments.
✔️ Prototypes are early versions tested for improvements.

5. Criteria → B: a set of measurable standards or specifications the design must meet.
✔️ Criteria are goals or requirements (e.g., "must hold 10 lbs").

6. Engineering Design Process → ? Wait — there’s no definition labeled “F” or matching the full process.

But wait! The list only has options A–E, but we have 6 words. Let's double-check.

Actually, option E is already used for "Engineer", and option C is for "Prototype". So let’s look again.

Wait — "Engineering Design Process" is missing from the definitions?

No — actually, definition E says:
> E. A person who designs, builds, or maintains engines, machines, or public works

That’s Engineer, not the Engineering Design Process.

So perhaps there's a typo? But looking at the list:

- A: Constraint
- B: Criteria
- C: Prototype
- D: Troubleshoot
- E: Engineer

So "Engineering Design Process" is not defined among A–E. That seems like a mistake.

But wait — maybe I misread.

Let me re-express the definitions:

| Letter | Definition |
|-------|-----------|
| A | a limitation or restriction... (Constraint) |
| B | a set of measurable standards... (Criteria) |
| C | a working model used to test... (Prototype) |
| D | a problem-solving method... (Troubleshoot) |
| E | A person who designs... (Engineer) |

So none of them define Engineering Design Process.

But the word "Engineering Design Process" is listed as #6. That means either:
- There's a missing definition (F), or
- It's implied that one of these defines it?

But clearly, none of A–E define the Engineering Design Process.

However, based on context, perhaps the question expects us to realize that "Engineering Design Process" is the entire method used to solve problems, but since no definition matches it, maybe it's a trick?

Wait — perhaps "Engineering Design Process" is meant to be matched with the overall idea, but since it’s not defined, this might be an error.

Alternatively, maybe definition D is meant to describe the process? No — D describes troubleshooting.

Let’s assume that "Engineering Design Process" is not properly defined here. But likely, the intent was:

→ Perhaps the correct answer is not provided, but that can't be.

Wait — let’s recheck: Is there a possibility that "Engineering Design Process" is not one of the choices? No, it is listed as #6.

But no definition corresponds to it.

So unless there's a typo, this seems incomplete.

But perhaps we are supposed to skip it? Unlikely.

Wait — maybe definition D is being reused? No.

Alternatively, perhaps “Engineering Design Process” should be matched to a description of the steps, but none are given.

This suggests a possible error in the worksheet.

But let’s proceed carefully.

Let’s go back and see if any definition fits "Engineering Design Process".

The Engineering Design Process is a systematic approach to solving problems, typically involving steps like: Identify Problem → Brainstorm → Design → Build → Test → Improve → Share.

None of A–E describe that.

So unless one of the definitions is mislabeled, we cannot match it.

But notice: Definition D says:
> a problem-solving method used to identify the cause of a malfunction...

That sounds more like troubleshooting, which is part of testing/evaluation.

So likely, the definitions are mismatched.

But based on common usage:

✔ Final Matching:

1. Engineer → E
2. Constraint → A
3. Troubleshoot → D
4. Prototype → C
5. Criteria → B
6. Engineering Design Process → ✘ Not defined — possibly an error.

But perhaps "Engineering Design Process" was intended to be matched to a different definition? Or maybe it's a trick?

Wait — maybe "Engineering Design Process" is not meant to be matched to one of A–E? But the instructions say: "Match the word with its definition."

So all six words must be matched.

But only five definitions exist.

So there's a formatting issue.

Possibly, the original had six definitions, but one got cut off.

Alternatively, maybe "Engineering Design Process" is not a term needing a definition — but it is listed.

Given this, I suspect the intended answer for #6 is missing, but perhaps it's meant to be inferred.

But without a proper definition, we can’t match it.

So I will assume that the definitions are correct, and "Engineering Design Process" is not defined here — which is a flaw.

But moving forward, perhaps the student is expected to know that the Engineering Design Process is a series of steps to solve problems.

But since no option matches, this may be an error in the worksheet.

Let’s now move to the True/False questions.

✔ True/False Questions – Page 1

#### 1. T/F Engineers never make mistakes. Explain your answer.

✘ False

Explanation: Engineers do make mistakes. Mistakes are part of the learning and improvement process. In fact, engineers often use testing and evaluation to find and fix errors. The engineering design process includes steps like "test and evaluate" and "re-design," which show that mistakes are expected and corrected.

#### 2. T/F Engineers think creatively. Explain your answer.

✔ True

Explanation: Engineers must think creatively to come up with innovative solutions to problems. They often brainstorm multiple ideas before choosing the best one. Creativity helps in designing new products, improving existing ones, and solving complex challenges.

#### 3. T/F Engineers use math/science to solve problems but not real world knowledge. Explain your answer.

✘ False

Explanation: Engineers use both math and science and real-world knowledge. Real-world experience helps them understand practical limitations, user needs, safety concerns, and environmental impacts. For example, building a bridge requires physics (science), calculations (math), and knowledge of weather, terrain, and materials (real-world).

#### 4. T/F An engineer designs and builds products, machines, structures, and systems that help solve a specific problem. Explain your answer.

✔ True

Explanation: This is the core job of an engineer. Whether it’s designing a car, a water filtration system, or a smartphone, engineers create solutions to real-world problems. Their work is goal-oriented and focused on functionality and efficiency.

✔ Page 2: Match the Step to the Real-Life Example

Now we match the Engineering Design Process steps (1–10) to the real-life examples (A–J).

Let’s list the steps and analyze each scenario.

#### Step-by-step Matching:

1. Identify the Problem → F: "The cleaners that Reid bought from the store just never seemed clean the grease on his stove very well."
✔️ This is identifying the issue — the store-bought cleaner doesn’t work.

2. Brainstorm/Research → B: "Instead of using the store-bought products, he decided to try some other household products... He looked through his cabinets and came up with a number of ideas..."
✔️ Brainstorming alternative solutions using available items.

3. Choose the Best Solution → A: "He decided to first try diluted vinegar."
✔️ After brainstorming, he picks one idea to test.

4. Design → J: "With the materials he had available, he decided a spray bottle would be best to use for the mixture."
✔️ Deciding how to deliver the solution — designing the delivery method.

5. Build → G: "He took a spray bottle and filled it up half way with vinegar and the other half with water."
✔️ Constructing the prototype (the cleaning solution in a spray bottle).

6. Test and Evaluate → I: "He sprayed the stove top, dried it off and determined that it still did not take off the grease as good as he wanted."
✔️ Testing the solution and evaluating its effectiveness.

7. Re-designing → H: "After that he decided to try making a paste of water and baking soda."
✔️ Changing the design (from liquid to paste) based on feedback.

8. Re-build → E: "She mixed the 2 tablespoons of baking soda with a tablespoon of water in a small dish."
✔️ Building the new version (the paste).

9. Re-test and Re-evaluate → C: "After applying that to the stove top and scrubbing for a little bit, it did remove the grease."
✔️ Testing the revised design and seeing if it works better.

10. Share Solution/Conclusion → D: "She ended up writing an email to all of her friends about what had worked..."
✔️ Sharing the successful solution with others.
