Math
Cian measured and aligned the edges of his paper, creating precise right angles and equal triangles that formed the basis of a balanced Pteroplane. He calculated the proportions of each wing section, recognizing how the relative lengths of the folds affected stability, and he compared these lengths to practice estimation and basic measurement concepts.
Science
Cian investigated the Coanda Effect and Bernoulli Principle, initially hypothesising they were the same phenomenon, then used online research to find experimental evidence that disproved his idea, clearly describing how the Coanda Effect involves fluid attachment to a surface while Bernoulli relates pressure to speed. He also observed his Pteroplane in flight, linking its streamlined shape to lift, and systematically varied launch angles to record which produced the longest flight, thereby deepening his grasp of fluid dynamics and the scientific method.
Tips
To extend Cian's learning, have him design and test his own paper wing variations, recording lift data to create a simple graph; set up a water‑flow experiment using a curved channel to visualise the Coanda Effect in real time; use a free‑online flight simulator to model how changes in wing curvature influence lift and drag; and guide him to write a comparative essay that cites at least three credible sources, reinforcing research skills and scientific argumentation.
