Grade 4 students examine three classic challenges — egg drop, newspaper bridge, and solar oven — through nine fill-in-the-blanks plus a matching activity. They identify cushioning materials, bridge tubes, foil reflectors, variables, and constraints. This worksheet teaches Grade 4 learners to spot the goal of each challenge, the tools used, and the science behind why each design works. Ideal practice before classroom build days and group iterations.

Engineering Design Challenges
Part A: Fill in the Blank
Write the missing word or number on each line.
1. In an egg drop challenge, students protect a raw egg from breaking when dropped.
2. Cushioning materials like cotton or bubble wrap help slow the egg before it lands.
3. A newspaper bridge is built only from rolled paper and tape to hold weight.
4. Rolling newspaper into tight tubes makes it much stronger than flat sheets.
5. A solar oven uses sunlight to heat food without electricity or fire.
6. Solar ovens often use shiny foil to reflect sunlight onto the food inside.
7. A variable is something the engineer changes to test how it affects results.
8. Engineers measure outcomes using a ruler for length and a scale for weight.
9. A constraint is something that cannot change, like time limits or available materials.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
Egg drop
→ Protect a falling egg

Newspaper bridge
→ Hold weight across a gap

Solar oven
→ Cook using sunlight
