Blackboard Physics (Mechanics)

thingiverse

A system for creating interactive physics demonstrations on blackboards, bulletin boards, and whiteboards was developed due to the high cost of similar equipment. This project aims to incorporate standard physics lab equipment into a comprehensive set of demonstrations. Being able to perform certain experiments on the board is invaluable, as it allows students to measure and analyze physical phenomena. Certain demonstrations can be easily replicated on a blackboard or whiteboard. For example, a pendulum's position at maximum amplitude can be marked, allowing students to calculate changes in height and amplitude. Projectile motion is another valuable demonstration that enables students to predict the path of an object under the influence of gravity. Currently available demonstrations include: * Balancing Lever * Pendulum * K'nex Pulley * K'nex Gears * Ramps for projectile motion Future developments will focus on: * Suction cup options with a strong magnet to handle weight-based demonstrations * Physical vectors that can be moved and scaled * General improvements to the design Suggestions are welcome, and 1/2" magnets have been identified as a suitable option. This project is designed for physics courses and can be used throughout various lessons. The duration of most lessons can be completed within a standard 40-minute period. Preparation involves some K'nex pieces and gluing magnets in place. References include any physics textbook, Phet Simulations, and the Phet simulation website. Assessment includes standard physics assessments, quizzes, and tests, as well as handouts provided by the Phet simulation website. The objectives of this project are for students to learn about projectile motion, Newton's Laws, gear ratios, pendulum period and frequency, balancing torques, and vector addition. The target audience is 5-12 year old physics students. Skills learned include vector addition, Newton's Laws, balancing torque, and the period/frequency of a pendulum.
