1. Toy Helicopters Teri Strugnell, Ben Brumpton and Braden Mulholland St George State High School

2. An experiment was conducted to determine which material and design created the best collapsible toy helicopter. To do so, material; wing size; and wing shape were altered, and each was dropped from a constant height of 2m in constant conditions. A total of 50 trials were conducted to ensure results were accurate and reliable.

4. Box plots wereconstructed for thetop five models, todetermine if therewere any significantdifferences betweentimes. Thisdemonstrates themajority of the datafor the length of11.5cm variable liesgreater than therest.

5. A histogram was then created to interpret the spread of the data for the “best design”. It shows the times are evenly distributed.

6. The data shows that the best collapsible toy helicopter has a wing length of 11.5cm, as when dropped it took the longest time to float to the ground. Extensions on this data could be testing diverse variables, however the number of trials and the number of variables are practical, given time restraints, and indicative of accurate results.
