Math
Cian recorded the flight distances of his basic paper plane over five trials and then added the five measurements together before dividing by five to find the average distance, demonstrating his grasp of calculating mean values. He repeated the same procedure after modifying the plane, producing a second average and comparing the two to see how the design change affected performance. By subtracting the first average from the second and interpreting the percentage change, Cian practiced subtraction, division, and proportional reasoning. Throughout the activity he organised his data in a Lapbook, reinforcing systematic data collection, arithmetic operations, and basic statistical analysis.
Tips
To deepen Cian’s understanding, have him graph the trial results for each design on a bar chart to visualise variation and range. Introduce a simple hypothesis‑testing step where he predicts which design will travel farther and then evaluates the outcome. Extend the investigation by changing another variable (wing shape, weight, launch angle) and recording a new set of averages to see cumulative effects. Finally, guide Cian to calculate the median and mode of each data set to compare different measures of central tendency.
