Math
Cian watched the video, sketched a precise diagram of the dihedral angle, and recorded the angle measurements on his flight log. He measured the flight distances of his paper plane both without and with the dihedral angle, noting the numeric results in centimeters. By calculating the difference between the two sets of distances, Cian practiced subtraction and ratio concepts to determine how much farther the plane traveled. He also compared multiple trials, which required him to organize data in a table and interpret the patterns mathematically.
Tips
To deepen Cian's mathematical understanding, have him graph the flight distances before and after adding the dihedral angle on a coordinate grid to visualise trends. Encourage him to compute the average distance for each configuration and then express the improvement as a percentage increase. Let Cian experiment with varying the dihedral angle in 5-degree increments and record the results, turning the activity into a mini‑investigation of how angle size affects range. Finally, guide him to write a short report that includes his data tables, graphs, and a conclusion supported by the numbers.
