4. Discussion

4.1 Key findings
      The larger the wing area, the lesser the distance it travels.

4.2 Explanation of key findings
      When there is a smaller wing area, the plane will fly further due to being more streamlined and being able to harness the elastic potential energy from the launch and convert it into kinetic energy.
      Having a big wing area means having greater lift, but much more drag. Thus, the planes will not be able to harness the elastic potential energy and thus fly a shorter distance.

4.3 Evaluation of hypothesis
      The hypothesis is correct that wing area affects the distance travelled by the glider.

4.4 Areas for improvement
      Greater detail in results
      Build a stronger launcher as it broke midway through experiment
