Grade 3 Engineering Design Practice Test

Explore Grade 3 Science with five 10-question practice tests on design problems, criteria, constraints, prototypes, testing, evidence, and redesign.

Engineering Design Practice Tests

These Grade 3 Science practice tests help students understand how engineers solve problems. Students identify criteria and constraints, plan and build prototypes, test ideas, use evidence, and improve designs.

Skills covered

  • Defining a design problem
  • Identifying criteria and constraints
  • Planning and building a prototype
  • Testing a solution fairly
  • Collecting and interpreting evidence
  • Redesigning and communicating results

How to use these practice tests

Start with the problem or need. Then identify what the solution must do, what limits the design, how the prototype will be tested, and what evidence can guide an improvement.

1. QuestionMultiple choice

Which criterion would be important for a bridge design?

Please select an answer first.

Correct answer: A

The correct answer is The bridge must hold a certain amount of weight..

  1. Read the design task: Identify the problem, requirement, material, test, or result described.
  2. Apply the design process: Holding a required weight is a measurable performance criterion.
  3. Check the choice: The correct choice is The bridge must hold a certain amount of weight..

Holding a required weight is a measurable performance criterion.

2. QuestionMultiple choice

Which material might help build a light paper airplane?

Please select an answer first.

Correct answer: B

The correct answer is A sheet of paper.

  1. Read the design task: Identify the problem, requirement, material, test, or result described.
  2. Apply the design process: Paper is a reasonable material for designing and testing a paper airplane.
  3. Check the choice: The correct choice is A sheet of paper.

Paper is a reasonable material for designing and testing a paper airplane.

3. QuestionMultiple choice

What could be a criterion for a simple water filter?

Please select an answer first.

Correct answer: C

The correct answer is The water should look clearer after passing through it..

  1. Read the design task: Identify the problem, requirement, material, test, or result described.
  2. Apply the design process: Clearer water is an observable result the filter can be designed to achieve.
  3. Check the choice: The correct choice is The water should look clearer after passing through it..

Clearer water is an observable result the filter can be designed to achieve.

4. QuestionMultiple choice

What is a constraint in a design for shade?

Please select an answer first.

Correct answer: D

The correct answer is The shade structure must fit in a small space..

  1. Read the design task: Identify the problem, requirement, material, test, or result described.
  2. Apply the design process: A small available space limits the size of the design.
  3. Check the choice: The correct choice is The shade structure must fit in a small space..

A small available space limits the size of the design.

5. QuestionMultiple choice

What makes a test fair?

Please select an answer first.

Correct answer: A

The correct answer is Changing one important factor while keeping other conditions the same.

  1. Read the design task: Identify the problem, requirement, material, test, or result described.
  2. Apply the design process: A fair test makes it easier to identify what caused the result.
  3. Check the choice: The correct choice is Changing one important factor while keeping other conditions the same.

A fair test makes it easier to identify what caused the result.

6. QuestionMultiple choice

Why should an engineer choose materials carefully?

Please select an answer first.

Correct answer: B

The correct answer is Different materials have different properties and uses..

  1. Read the design task: Identify the problem, requirement, material, test, or result described.
  2. Apply the design process: Strength, flexibility, weight, and other properties affect how materials perform.
  3. Check the choice: The correct choice is Different materials have different properties and uses..

Strength, flexibility, weight, and other properties affect how materials perform.

7. QuestionMultiple choice

What does a failed prototype teach an engineer?

Please select an answer first.

Correct answer: C

The correct answer is Which parts or ideas need to change.

  1. Read the design task: Identify the problem, requirement, material, test, or result described.
  2. Apply the design process: A prototype that does not work provides evidence for improvement.
  3. Check the choice: The correct choice is Which parts or ideas need to change.

A prototype that does not work provides evidence for improvement.

8. QuestionMultiple choice

What is redesign?

Please select an answer first.

Correct answer: D

The correct answer is Changing a design based on test results.

  1. Read the design task: Identify the problem, requirement, material, test, or result described.
  2. Apply the design process: Redesign uses evidence to make a solution work better.
  3. Check the choice: The correct choice is Changing a design based on test results.

Redesign uses evidence to make a solution work better.

9. QuestionMultiple choice

Which evidence shows that a paper airplane design improved?

Please select an answer first.

Correct answer: A

The correct answer is The new airplane flew farther in the same test conditions..

  1. Read the design task: Identify the problem, requirement, material, test, or result described.
  2. Apply the design process: A greater distance under the same conditions is evidence of improved performance.
  3. Check the choice: The correct choice is The new airplane flew farther in the same test conditions..

A greater distance under the same conditions is evidence of improved performance.

10. QuestionMultiple choice

Which is the best conclusion about testing designs?

Please select an answer first.

Correct answer: B

The correct answer is Testing helps engineers learn what works and how to improve a solution..

  1. Read the design task: Identify the problem, requirement, material, test, or result described.
  2. Apply the design process: Testing provides information that guides better design decisions.
  3. Check the choice: The correct choice is Testing helps engineers learn what works and how to improve a solution..

Testing provides information that guides better design decisions.
