An Eclipsing Binary System with a Precessing Accretion Disk
Students work together to complete an experiment over binary sources. They determine values for the orbital period of certain objects and interpret intensity changes. They also calculate a value for the period of precession of an...

What Floats Your Boat?
Young scholars discover the Archimedes principle through a buoyancy experiment. They measure the water displacement of a lump a clay which is denser than water then reshape the clay into a bowl which floats but displaces more water.

Animating Motion
Students apply what they recall about objects in motion by animati ng sequences of pictures that model a set of physical conditions. They animate the orbital motions of the Earth, the space shuttle, and the Moon based on calculations of...
