PENDULUM PROBLEM -EXPERIMENTAL DESIGN INVESTIGATIONHow does mass, drop height, and string length affect the period of a pendulum?* Budget friendly* Safe and simple materials* Easy set up and clean upStudents will investigate how manipulating variables on a simple pendulum will affect the period ( swing time).. Students will construct a hypothesis, manipulate variables, collect data, analyze data, and draw conclusions based on their data. Teacher can extend investigation into an engineering
