Affordable, Easy, Fun
Present these demonstrations in front of your class to excite your students about learning core physics concepts. Set up and execution are simple, so you can spend more time engaging your students. Ideal for introducing a unit or using as reinforcement after a lesson, these demos are available for all fundamental physical science topics.
Two demonstrations in one, this system uses both free fall and a pulley system to illustrate chain reactions. Using the two strings with washers provided, students conduct an experiment based on the spacing of the washers on the string.
The action being observed is the string with washers falling onto a metal plate. If the washers are equally spaced, the time between hits decreases. If properly spaced, the time between hits is a constant. The pulley system serves as a way to reduce total acceleration of the system, giving the students longer time intervals to hear and discern the difference between the two types of washer spacings.
Includes two pre-made 5 meter long strings with washers and instructions. Support stands are required, but not included.
