Projectiles Lab - From the experiment I conclude that indeed, the range of a projectile does depend on the angle at which it is projected. Moreover, up until around 40-50 degrees,

Distance rubber band pulled back each time: 20 cm

Note: all range distances achieved are given as where the rubber band made impact with the floor, NOT where it eventually came to a standstill.

Conclusion

Improving the investigation

        Were we to repeat an experiment of a similar nature over again, there are several changes I would implement to limit the weaknesses.  Firstly, by using a marble or some sort of more dense and inelastic material you minimize interference from the wind greatly.  Although it is true that you cannot project a marble simply with an incline plane like we did with the rubber band, but some sort of projection gun device could be obtained.  Another realistic suggestion would be to use a protractor instead of trusting the markers on the incline plane.  I believe this would slightly increase the accuracy since the protractors are pretty clear.
