Math
Cian modified a paper plane by adding ridges and then launched both the altered and original models. He measured the distance each plane travelled in metres and timed how long each stayed aloft in seconds, recording the data in his Flight Log. Using the recorded values, Cian calculated the average speed of each plane by dividing distance by time, applying basic ratio and rate concepts. By comparing the two speed results, he determined whether his modifications improved the planes' performance.
Tips
To deepen Cian's understanding, have him repeat the experiment with at least three trials per design and compute mean, median, and range of the speeds. Introduce graphing by plotting distance versus time for each plane on a scatter chart to visualise trends. Encourage Cian to experiment with different wing shapes or weights, then calculate the percentage change in speed to practice percentage increase/decrease. Finally, link the findings to real‑world contexts, such as how engineers use speed and distance data when designing aircraft.
