Nebula in a Jar
Source Institutions
In this activity, learners will build a model of a nebula using cotton balls and colored water. Astronomers photograph nebulas and add colors to provide information about the nebula's composition.

Stroboscope
Source Institutions
In this activity (posted on March 20, 2011), learners follow the steps to construct a stroboscope, a device that exploits the persistence of vision to make moving objects appear slow or stationary.
