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.
