Paper Plane Fold & Measure (Year 7)

🎯 Purpose

Fair Test Investigation: We will change ONE variable (wing width or fold type) and keep everything else the same to see how it affects flight distance.

✈️ How to Fold Your A4 Dart Paper Plane

Step 1: Fold A4 paper in half lengthways → Unfold

Step 2: Fold top corners to centre line (triangle shape)

Step 3: Fold along centre line (plane in half)

Step 4: Fold wings up to make them level

📏 How to Measure Wing Width (Wing Span)

Wing Width = tip-to-tip measurement across both wings

[Diagram showing plane from above with ruler measuring across wing tips]

Use a ruler to measure from left wing tip to right wing tip in centimetres.

📊 Lesson 1: Different Wing Widths

Make 3 planes with different wing widths. Tick when measured correctly:

Wing Width Targets:

Plane A: Wing width = 5 cm

Plane B: Wing width = 10 cm

Plane C: Wing width = 15 cm

Record flight distances for each plane:
Plane A (5cm): Trial 1: _____ cm/m Trial 2: _____ cm/m Trial 3: _____ cm/m Average: _____ cm/m
Plane B (10cm): Trial 1: _____ cm/m Trial 2: _____ cm/m Trial 3: _____ cm/m Average: _____ cm/m
Plane C (15cm): Trial 1: _____ cm/m Trial 2: _____ cm/m Trial 3: _____ cm/m Average: _____ cm/m

📊 Lesson 2: Different Fold Types (Fixed 10cm Wing Width)

Make 3 planes, all with 10cm wing width but different fold types:

Fold Type 1: Short wings (fold wings up less)

Fold Type 2: Long wings (wing leading edge forward)

Fold Type 3: Upturned wings (tiny outer-tip kink upward)

Record flight distances:
Type 1: Trial 1: _____ cm/m Trial 2: _____ cm/m Trial 3: _____ cm/m Average: _____ cm/m
Type 2: Trial 1: _____ cm/m Trial 2: _____ cm/m Trial 3: _____ cm/m Average: _____ cm/m
Type 3: Trial 1: _____ cm/m Trial 2: _____ cm/m Trial 3: _____ cm/m Average: _____ cm/m

✅ Fair Test Checklist

Same paper type and size (A4)

Same basic fold steps

Measured wing width before each launch

Same launch method (same person, same force, same angle)
