In this Grade 3 worksheet, students practice planning, testing, and iterating through the engineering design process. Nine fill-in items cover materials, sketches, models, data, and improvement, while a matching task pairs each step with its key action. Aligned to NGSS 3-5-ETS1, this sheet helps Grade 3 engineers understand how testing data drives smarter design choices and stronger final solutions. This Grade 3 printable works well for classroom practice or homework.

Engineering Design Process
Grade 3
★ Part A: Fill in the Blank
Write the missing word or number on each line.
1) A plan shows the materials and steps engineers will follow.
2) Before building, engineers make a sketch or drawing of the idea.
3) A model shows how a real object might look or work.
4) When engineers test, they try the design to see if it works.
5) Grade 3 engineers write down data during a test.
6) A design that fails gives useful information about what to fix.
7) When engineers improve a design, they change parts to make it better.
8) Going back through the steps to try again is called an iteration.
9) Grade 3 teams share their results so other engineers can learn.
★ Part B: Matching
Match each item on the left to the correct answer on the right.
1) Match each item to its correct answer.
