This Grade 3 engineering design worksheet introduces the five-step cycle: ask, imagine, plan, create, test, and improve. Students practice key vocabulary like engineer, prototype, and improve with sentence correction, fill-in, and true-or-false items. Aligned to NGSS 3-5-ETS1, this sheet helps Grade 3 learners see engineering as careful problem solving and makes the design process easy to remember. This Grade 3 printable works well for classroom practice or homework.

Engineering Design Process
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
A engineer solve problem by design new thing.
Rewrite: An engineer solves problems by designing new things.
2. Fix the sentence:
Engineers ask about the problem before they builds it.
Rewrite: Engineers ask about the problem before they build it.
3. Fix the sentence:
The first steps of the design cycle is asking a question.
Rewrite: The first step of the design cycle is asking a question.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. An engineer is a person who designs things to solve problems.
2. The first step of the design cycle is to ask what the problem is.
3. After planning, engineers build a model called a prototype.
4. After testing, engineers improve the design to make it better.
Part C: True or False?
Read each statement. Circle True or False.
1. Engineers follow steps called the engineering design process.
True False
2. Engineers only need one try to make a perfect design.
True False
3. A prototype is a model used to test a design idea.
True False
