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.

  3. Check the choice: The correct choice is It keeps food cool until lunchtime..

Keeping food cool is a useful performance requirement for a lunchbox.

2. QuestionMultiple choice

Which is a constraint for a lunchbox design?

Please select an answer first.

Correct answer: B

The correct answer is It must fit inside a student’s backpack..

  1. Read the design task: Identify the problem, requirement, material, test, or result described.
  2. Apply the design process: The backpack size limits the lunchbox dimensions.
  3. Check the choice: The correct choice is It must fit inside a student’s backpack..

The backpack size limits the lunchbox dimensions.

3. QuestionMultiple choice

What should students do to test a lunchbox prototype?

Please select an answer first.

Correct answer: C

The correct answer is Measure how well it keeps food cool under the same conditions..

  1. Read the design task: Identify the problem, requirement, material, test, or result described.
  2. Apply the design process: A controlled temperature test provides evidence about the design.
  3. Check the choice: The correct choice is Measure how well it keeps food cool under the same conditions..

A controlled temperature test provides evidence about the design.

4. QuestionMultiple choice

What should an engineer do after finding a weak part in a prototype?

Please select an answer first.

Correct answer: D

The correct answer is Improve that part and test the new version..

  1. Read the design task: Identify the problem, requirement, material, test, or result described.
  2. Apply the design process: Redesigning and retesting uses evidence to improve the solution.
  3. Check the choice: The correct choice is Improve that part and test the new version..

Redesigning and retesting uses evidence to improve the solution.

5. QuestionMultiple choice

Which is a possible solution to the problem “Pencils roll off a desk”?
