Students can refer to the videos below to start learning about water rockets:
This water rocket challenge aims to provide a platform for school students to design, build and test a water rocket model based on scientific principles such as rocket propulsion theory, aerodynamics, and Newton’s third law with the goal of educating school students on the actual science behind the creation of water rockets. Through this competition, school students are encouraged to conduct research on science and engineering during the design phase of their work.
The water rocket models should be built by each team entering this competition prior to the Competition Day on 27/9/2014. Only completed models will be launched and evaluated on the Competition Day.
Details of the Water Rocket Challenge:
- Only one category shall be competed – Water rocket with parachute deployment system.
- Each water rocket model must be equipped with a parachute. Rockets without a parachute deployment system will be disqualified. Parachutes must be installed on the upper component of the rockets.
- The rocket should be designed in a way that will keep it airborne for a long amount of time. Time airborne will be noted.
- Only 1.5 litter Coca-Cola / Sprite / F & N Carbonated Drink PET (Polyethylene terephthalate) bottles are to be used. Combustible chemical materials, pointed materials, metal, and other harmful materials that can cause injury and death are not allowed to be used.
- All rockets will be launched at a launch pressure of 8 atmospheres (atm).
- Each team is allowed to make one (1) launch only.
- Setup of water rockets to the launcher will be done by the organizers only. Students are only allowed to launch their rockets with the permission of the organizers.
- Launches will be made at a launch angle of 90°.
- Each water rocket will be timed from the moment of launch right up to the moment it either falls to the ground, gets tangled up with another object like a tree or building or fence, flies out of the judges’ sight, or is airborne for more than 15 minutes.
- Judging criteria will be based on the longest time the water rocket is airborne. Entries will also be judged on the level of creativity, understanding and depth of research conducted during the design stage. Each team must prepare and bring to the Competition day a poster with pictures that describes about their water rocket and explain their process of building it.
