This Grade 4 medium sheet deepens trade-off thinking with new scenarios about cost, weight, flow, and speed. Students fill in nine sentences using terms like trade-off, criteria, and limits, then match design choices to outcomes such as cleaner water but slower flow. The matching set highlights how every decision gains one feature while giving up another. Grade 4 students leave the sheet ready to defend design choices with clear reasons.

Engineering Design Challenges
Part A: Fill in the Blank
Write the missing word or number on each line.
1. Picking the best idea from a brainstorm uses your criteria.
2. An idea that costs less but breaks faster has a clear trade-off.
3. A bridge using cardboard is light, but it is not very strong.
4. Brainstorming works best when teams write down many ideas.
5. An airplane with heavy clay flies short but very straight.
6. A water filter with small holes cleans well but slows the flow.
7. A marble run with tight turns is exciting but loses speed.
8. Engineers choose the design that best meets goals and limits.
9. Two solutions compared on a chart help show every trade-off.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
Cheaper materials
→ Lower cost but weaker build
Lower cost but weaker build
Wider airplane wings
→ Steadier flight but slower speed
Steadier flight but slower speed
Smaller filter holes
→ Cleaner water but slower flow
Cleaner water but slower flow
Tight marble track turns
→ More excitement but lower speed
More excitement but lower speed
