Curated OER
Timing An X-ray Pulsar
Students use X-ray data to identify an object as a rotating neutron star, and determine its period of rotation. They use XTE observations of the Crab Pulsar to determine the period of the light intensity, interpret this period as the...

Scientific Inquiry: Periodic Motion
Students construct their own pendulum. In this physics lesson, students design an experiment to find the factors affecting its period. They formulate a conclusion based on experimental data.
