Concrete Frisbee Contest
The Basics:
Each team of students will design and construct a Frisbee made of concrete. This event will enable students to design, build and test a Frisbee. This will be the second year for this competition and we expect the entries to be much improved in design and performance compared to last year. Schools can have multiple entries.
Design Rules:
1. Each team should have at least 2 participants.
2. Each team may bring 2 Frisbee’s to the competition, one for distance and one for accuracy.
3. The primary material must be Portland cement. No other materials such as duct tape, string, plastic, etc. can be used.
4. All reinforcement materials must be non-metallic(such as a carbon or fiberglass mesh should be used).
5. The Frisbee must be circular and 8” to 10” in overall diameter.
6. The Frisbee must be 1 to 2 inches thick.
7. Molds can be used to form the shape. Examples: pie pans, old plastic Frisbees, wooden forms. One suggestion would be to build a layer of cement, then a mesh layer, then another layer of cement and so on.
8. The design is important for a uniform, smooth surface texture. The strength is important for durability and the weight is important for distance.
1. Each Frisbee will be initially judged on design, quality of construction, and creative finish that is applied. The Frisbee can be painted, decaled or finished in any way the teams choose.
2. The condition of the Frisbee after throwing will be judged for durability.
Throwing Competition
· Distance competition
Each team will have two opportunities to throw the Frisbee. The longer of the two throws will be recorded. The distance recorded will be from the base line to where the Frisbee touches the ground. If the Frisbee hits outside the boundary lines, that throw will not be counted.
· Accuracy competition
A fixed target will be placed some distance from the base line. Each team will have two throws of the Frisbee. The better of the two throws will be counted. The throw that lands closest to the target wins.
