P3

STANDARD P3: FORCES AND MOTION Students identify interactions between objects either as being by direct contact (e.g., pushes or pulls, friction) or at a distance (e.g., gravity, electromagnetism), and to use forces to describe interactions between objects. They recognize that non-zero net forces always cause changes in motion (Newton’s first law). These changes can be changes in speed, direction, or both. Students use Newton’s second law to summarize relationships among and solve problems involving net forces, masses, and changes in motion (using standard metric units). They explain that whenever one object exerts a force on another, a force equal in magnitude and opposite in direction is exerted back on it (Newton’s third law).
P3.1 Basic Forces in Nature	Astronomy - Students will demonstrate an understanding of the basic concepts relating to variable star astronomy. Boomilever - The objective of this event is to design and build the lightest cantilevered wooden structure which, when attached to a vertical Testing Wall at one end, will support a load up to 1.5 Kg at the distal end. Teams should maintain and submit a log at check-in containing information about the structures they have built that can be used to improve future designs. Electric Vehicle - Contestants will construct a "vehicle" which uses electrical energy as its sole means of propulsion. They should be able to adjust the vehicle to travel a distance specified by the judges and to predict the time it will take to travel that distance. Robot Ramble - The object of this event is to design and build a robot capable of performing certain tasks on a prescribed playing field. Wright Stuff - Teams will construct and test up to two rubber-powered model monoplanes to achieve maximum flight times.
