Product Details

Clearly convince your students that a projectile follows a parabolic path! Launch a ball bearing using the unique launching mechanism, and watch the ball skim the surface of the track which is in the shape of a parabola. Connect the optional PSworks Photogate Timer to the track to demonstrate the conservation of energy-the projectile's speed is the same when it's at the same height, whether it's going up or down. Flipping the Parabola over coverts it to a conservation of energy track. Show students that a ball will roll to the same starting height even if the path to get there is longer or shorter. This two-for-one demonstration apparatus is a versatile addition to your physics equipment. Made from durable hardwood-it will last for years! Teacher instructions and student worksheet are provided. PSworks Stand, or equivalent, is required. PSworks Photogate Timer is a recommended option.

Performance Expectations

MS-PS1-2: Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
MS-ETS1-4: Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.
