» - » You must have a project design form signed by your science teacher before you begin your project. The project design form and this form must be returned with your project. Failure to return both forms will result in a penalty of 5%. If you begin your project before obtaining your science teacher's signature on the project design form, your project may be disqualified. » - » Check the TARGET GRADE (most likely your maximum grade) at the top of the page. » - » You may not use AC electricity to power your project. Only DC electricity of less than 5 amperes & 15 volts is permitted. » - » You may not copy another student's design for your project (except for bridges & towers). Yours must be significantly different. » - » You may not do the same project twice without permission from your science teacher. » - » In order to earn “bonus points” and extra credit, your project must be handed in by the due date, and must earn at least 96 %. » - » Projects handed in more than 4 days late will not be presented or tested in class. » - » You must complete a project design form and get it signed by your teacher before you begin your project. |
| OBJECTIVE -The objective of this exercise is to construct a rubber band powered plane that will fly 5 m (16 feet, 8 inches) or stay aloft 4 seconds without hitting anything. |
| PROJECT GUIDELINES
1. Read the INDEPENDENT PROJECT GENERAL GUIDELINES first. 2. Complete a project design form and get it signed by your science teacher. 3. Planes must be powered by one or more rubber bands. 4. Three trials will be allowed with the best of the three taken for your score; 5. There are no restrictions on building materials or size except that the airplane - may not be powered by rubber tubing or elastic cargo straps (bungee cords). - must have wings spanning at least 2 inches for each 8 inches of length; - must be propeller driven with power for the propeller(s) being supplied by rubber bands. - may not be launched with a mechanical launching device. Launching must be by a gentle toss (no more than 30 cm hand movement) or self propelled take-off. - may not be made from a "kit" and may not be made from construction set parts (Legos® parts, Erector®set parts, etc,) except for .propeller(s), gears, axles and wheels. 6. You must successfully demonstrate the plane to your class to receive full credit. 7. See the Grading Criteria for how you can earn an A+.* |
