Visual Scientifics PTPROJ Projectile Launcher

Visual Scientifics projectile launcher is used to study kinematic equations, and conversion between gravitational potential and kinetic energy. Students participate in an interactive experiment for measuring the muzzle velocity of the launcher to identify varying launch angles in order to quantify the initial kinetic energy of the projectile (ball). Using their velocity calculations, students then make predictions about where the ball will land. The kit includes a projectile launcher, mounting hardware, ball, and a protractor with bob for hands-on learning, and has steel construction for durability. Steel is a good general-purpose material, with better weldability and increased rust resistance over wrought iron. The launcher’s 23-page instructions cover 3 to 4 hours of class and lab time, and include a main lab, “Inquiry-Led Activity to Experimentally Verify Projectile Equations,” and two extensions, “Technology-Based Verification of Theoretical Modeling” and “Using Experimental Results to Meet Design Criteria.” The instructions also contain safety information, general theory, classroom lessons, experiment set up diagrams, student lab book, 12 Next Generation Science Standards Concepts, and 10 Common Core Standards. The kit requires the PTBASE base for operation; optional accessories include a video camera for the extensions, graphing software, carbon paper, and PTPGS photogate (required and optional accessories sold separately). The loop kit is suitable for high school and college students, or ages 14 to 21.

Science education products incorporate applied math and science principles into classroom and homeschool-based projects. Teachers in pre-K, elementary, and secondary classrooms use science education kits and products alongside science, technology, engineering, and math (STEM) curriculum to demonstrate STEM concepts and real-world applications through hands-on activities. Science education projects include a broad range of activities, such as practical experiments in engineering, aeronautics, robotics, energy, chemistry, physics, biology, and geology.

Visual Scientifics brand products, manufactured by EISCO Scientific, include lab supplies and equipment for physical science education. Founded in 1968, EISCO is headquartered in Rochester, NY, and meets International Organization of Standardization (ISO) standard 9001: 2000.
