Catapult Design
Objective
Design and produce a working catapult, within specified guidelines, that is adjustable and propels marble (weighing about 5.2 grams each) at the MPR in 60 minutes.
General Rules
Catapults must be safe and controllable. Participants are responsible for the safety of the operation of their design. Prior to competition, judges will disqualify any catapult that appears unsafe.
The catapult should be of sufficiently stable to ensure that it remains stable the launch line after the projectile has been launched
Judge’s score will be based on aesthetics, creativity and efficiency of design as described in the attached scoring guidelines.
Competition Format
Each team will be given 60 sets of wooden chopsticks, 50 rubber band, a bottle cap, hot glue, bottle cap and 60 minutes to complete their designs.
No extra time will be given to any team for any reason.
To participate in the tournament, a team must be registered with Mr.Aybars. Each team can consist of 3 or less people. This team can submit only one catapult in the competition.
All catapult must be set up in the assigned areas. You will be given notice of this area well in advance.
Each team will have 5 chances to launch their marb the farthest. Distance will be measured from the center-point of the leading edge of the catapult to the location of the launched marble.
No part of the catapult shall cross the firing line after launch.
If your catapult fails projecting the marble in 3 successive trials you will be eliminated.
Judging
Two judges provided by science department.
