Paper aeroplane challenge

All of the P5 classes took part in a paper aeroplane challenge today. We researched what aids efficient flight e.g. wingtips, aerodynamic shape and balance. We then tested our designs in a shady area of The Meadows (it was hot today). Finally each person had 2 throws to get their aeroplane to fly as far as they could. In Primary 5C the winner was Andrew, followed by Laila and Qing Yang. Can you spot why they travelled a good distance?
