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

What is often the first step in an engineering design process?

Please select an answer first.

Correct answer: A

The correct answer is Ask what problem needs to be solved..

  1. Read the design task: Identify the problem, requirement, material, test, or result described.
  2. Apply the design process: Engineers first identify and understand the problem or need.
  3. Check the choice: The correct choice is Ask what problem needs to be solved..

Engineers first identify and understand the problem or need.

2. QuestionMultiple choice

What happens during the imagine step?

Please select an answer first.

Correct answer: B

The correct answer is Engineers think of possible solutions..

  1. Read the design task: Identify the problem, requirement, material, test, or result described.
  2. Apply the design process: Imagining means brainstorming ideas that might solve the problem.
  3. Check the choice: The correct choice is Engineers think of possible solutions..

Imagining means brainstorming ideas that might solve the problem.

3. QuestionMultiple choice

What happens during the plan step?

Please select an answer first.

Correct answer: C

The correct answer is Engineers decide how to build and test an idea..

  1. Read the design task: Identify the problem, requirement, material, test, or result described.
  2. Apply the design process: Planning includes choosing materials, drawing steps, and considering criteria and constraints.
  3. Check the choice: The correct choice is Engineers decide how to build and test an idea..

Planning includes choosing materials, drawing steps, and considering criteria and constraints.

4. QuestionMultiple choice

What happens during the create step?

Please select an answer first.

Correct answer: D

The correct answer is Engineers build a prototype or model..

  1. Read the design task: Identify the problem, requirement, material, test, or result described.
  2. Apply the design process: Creating means making a model that can be tested.
  3. Check the choice: The correct choice is Engineers build a prototype or model..

Creating means making a model that can be tested.

5. QuestionMultiple choice

What should engineers do after creating a prototype?

Please select an answer first.

Correct answer: A

The correct answer is Test it and collect evidence..

  1. Read the design task: Identify the problem, requirement, material, test, or result described.
  2. Apply the design process: Testing shows how the prototype performs.
  3. Check the choice: The correct choice is Test it and collect evidence..

Testing shows how the prototype performs.

6. QuestionMultiple choice

What should engineers do if a prototype does not meet a criterion?

Please select an answer first.

Correct answer: B

The correct answer is Redesign it and test the improved version..

  1. Read the design task: Identify the problem, requirement, material, test, or result described.
  2. Apply the design process: Redesigning allows engineers to use evidence to improve the solution.
  3. Check the choice: The correct choice is Redesign it and test the improved version..

Redesigning allows engineers to use evidence to improve the solution.

7. QuestionMultiple choice

Which question checks a design criterion?

Please select an answer first.

Correct answer: C

The correct answer is Does the bridge hold the required number of blocks?.

  1. Read the design task: Identify the problem, requirement, material, test, or result described.
  2. Apply the design process: The question checks whether the design meets a performance requirement.
  3. Check the choice: The correct choice is Does the bridge hold the required number of blocks?.

The question checks whether the design meets a performance requirement.

8. QuestionMultiple choice

Which is a constraint for a paper bridge challenge?

Please select an answer first.

Correct answer: D

The correct answer is The bridge may use only ten craft sticks..

  1. Read the design task: Identify the problem, requirement, material, test, or result described.
  2. Apply the design process: The limited number of craft sticks is a material constraint.
  3. Check the choice: The correct choice is The bridge may use only ten craft sticks..

The limited number of craft sticks is a material constraint.

9. QuestionMultiple choice

Why might engineers compare two prototypes?

Please select an answer first.

Correct answer: A

The correct answer is To see which one meets the criteria more successfully.

  1. Read the design task: Identify the problem, requirement, material, test, or result described.
  2. Apply the design process: Comparing results helps engineers choose or improve a solution.
  3. Check the choice: The correct choice is To see which one meets the criteria more successfully.

Comparing results helps engineers choose or improve a solution.

10. QuestionMultiple choice

Which statement best describes the engineering process?

Please select an answer first.

Correct answer: B

The correct answer is It can repeat as engineers test, learn, and improve their designs..

  1. Read the design task: Identify the problem, requirement, material, test, or result described.
  2. Apply the design process: Engineering is iterative, so testing and redesign may happen several times.
  3. Check the choice: The correct choice is It can repeat as engineers test, learn, and improve their designs..

Engineering is iterative, so testing and redesign may happen several times.
