Math
Cian watched a video on dihedral angles, then sketched an accurate diagram and logged the measured angles in his flight log. He measured the flight distances of his paper plane with and without the dihedral angle, recording the results in centimetres. By subtracting the shorter distance from the longer one, Cian practised subtraction and used ratios to express how much farther the angled plane travelled. He also organised the data from multiple trials in a table, interpreting patterns to see how the angle affected performance.
Tips
To deepen Cian's understanding, try a design challenge where he creates planes with different angle sizes and predicts the distance before testing. Introduce a simple graphing activity so he can plot distance versus angle and see trends visually. Incorporate a real‑world scenario, such as estimating how far a kite might travel with a similar wing tilt, encouraging him to apply ratio reasoning beyond the classroom. Finally, let Cian write a short reflection explaining why the dihedral angle changed the flight, linking the math to aerodynamic concepts.
