Grade 4 learners explore real-world engineering wins like skyscrapers, dams, bridges, and prosthetic limbs in this matching-focused worksheet. They identify which structure solves which problem, fix subject-verb errors, and explain how engineers improve daily life. Through fill-in-the-blank and short-answer questions, Grade 4 students see that engineering is everywhere — in their homes, hospitals, and cities, helping people travel, live, and move safely each day.

Engineering Design Challenges
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
Skyscrapers is tall buildings made of steel and glass.
Rewrite: Skyscrapers are tall buildings made of steel and glass.
2. Fix the sentence:
A dam hold back water to make electricity and stop floods.
Rewrite: A dam holds back water to make electricity and stop floods.
3. Fix the sentence:
Prosthetic legs helps people who lost a limb walk again.
Rewrite: Prosthetic legs help people who lost a limb walk again.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. A skyscraper is a very tall building, often built in big cities.
2. A dam blocks river water and can be used to make clean electricity.
3. A prosthetic limb replaces a missing arm or leg and helps a person move.
4. Engineers design bridges so cars and people can safely cross rivers or canyons.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. Why do engineers design prosthetic limbs?
Engineers design prosthetic limbs to help people who have lost an arm or leg walk, run, or hold things, giving them back independence and confidence.
2. Pick one structure (skyscraper, dam, or bridge) and explain its purpose.
A bridge lets cars and people safely cross a river or valley, so travelers do not have to drive long distances around the gap.
