In this two-day STEM challenge, you’ll design, test, and improve a paper airplane. You’ll collect data from multiple trials, create graphs, and use evidence to justify design changes—then compete in a class tournament using a combined score.
Day 1 — Before you test: Which option best describes the engineering design process you’ll use in this paper-airplane challenge?
Day 1 — Data collection plan: Which information should your team record for each trial so you can calculate a combined score and make a fair comparison between designs? (Select 2.)
Day 1 — Accuracy scoring: What single, measurable value could you record each trial to represent accuracy to a target? (Answer in 1–3 words.)
Day 1 — Measurement quality: Which procedure will make your data the most reliable (consistent) across trials?
Day 1 — Trial plan: How many trials should you run for each design (baseline and redesign) to make a fair comparison in this 2-day challenge?
Day 1 — Redesign decision: Based on your baseline data, name ONE design change you will test next. (Answer in 1–3 words.)
Day 2 — Redesign justification: In 3–5 sentences, explain (1) what you changed, (2) which metric(s) it was meant to improve (distance, hang time, accuracy), and (3) what your data shows after re-testing.
Day 2 — Materials & fairness: Which change keeps the tournament fair while still allowing iteration?
Day 2 — Evidence-based iteration: Which actions count as using evidence to improve your design? (Select 2.)
Day 2 — Combined score: Your team’s combined score is based on distance, hang time, and accuracy. Which approach is the most fair for combining these three measurements into one score?
Day 2 — Graphing check: Which graph best shows a comparison between your baseline and redesign averages for distance, hang time, and accuracy?
Tournament submission: Write your team’s final plane name (1–3 words).
