This Grade 3 worksheet focuses on the create and test step of engineering design. Grade 3 students learn to build a simple prototype, run a fair test, record results, and decide whether to change the design. Activities use paper bridges, coins, and classroom materials so Grade 3 learners see that failing a test is part of learning. Vocabulary includes prototype, test, results, and change, aligned with NGSS 3-5-ETS1 engineering practices for elementary Grade 3 science classrooms everywhere today.

Engineering Design Process
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
In Grade 3, we builded a paper bridge prototype and tested it with coins.
Rewrite: In Grade 3, we built a paper bridge prototype and tested it with coins.
2. Fix the sentence:
Our Grade 3 prototype was more stronger than the first design we tested.
Rewrite: Our Grade 3 prototype was stronger than the first design we tested.
3. Fix the sentence:
The Grade 3 team tested there prototype to see if it could hold weight.
Rewrite: The Grade 3 team tested their prototype to see if it could hold weight.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. A first model that Grade 3 engineers build to try out an idea is called a prototype.
2. In Grade 3, after building a prototype, we test it to see if it works.
3. Grade 3 engineers write down what happens when they test, called results.
4. If a Grade 3 prototype fails the test, engineers can change the design and try again.
Part C: True or False?
Read each statement. Circle True or False.
1. In Grade 3, a prototype is the very last version of a product that goes to the store.
True False
2. Grade 3 engineers can build a prototype out of simple materials like paper, tape, and straws.
True False
3. In Grade 3, if a prototype fails, engineers should throw away the whole project forever.
True False
