Science
Cian designed and carried out a controlled experiment to investigate how different throwing techniques affect a paper plane’s flight, keeping the plane and venue constant while varying only the thrust applied by his hand. He formulated hypotheses such as "If I throw the paper plane hard, it will fly further," systematically tested each technique, recorded distances and flight times, and documented each step of the Scientific Method in his lapbook. By analysing the results, Cian identified patterns linking the magnitude and angle of the throw to flight performance and concluded that greater thrust and optimal launch angles increase distance. This process deepened his understanding of forces, independent and dependent variables, and evidence‑based reasoning.
Tips
Tips: 1) Have Cian redesign the plane’s wings and tail to explore how aerodynamic shape interacts with thrust, recording the new flight data. 2) Introduce a simple motion‑sensor app on a smartphone to capture launch speed and angle, turning qualitative observations into quantitative data. 3) Guide him to create a poster presentation that includes graphs, force‑vector diagrams, and a reflection on experimental errors, reinforcing scientific communication skills. 4) Encourage a mini‑competition where peers predict flight outcomes before testing, fostering peer review and hypothesis generation.
