By dropping a magnet through a copper tube, participants learn how the magnetics fields can still interact with nonmagnetic materials.
Polarization of Light
This demonstration explains transverse waves and some surprising properties of polarizers.
Marshmallows & the Speed of Light
This workshop uses marshmallows to teach participants about waves and to calculate the speed of light.
This demonstration provides a three-dimensional visualization of magnetic field lines using ferrofluid.
Reflection & Refraction
This demonstration presents viewers with an example of reflection and refraction and describes difference between the two.
Composition of the Universe
This demonstration briefly explains the history of the universe using jars and colored beads. The jars represent matter/objects and the beads represent the composition of those objects.
Participants use a hair to show how light can interfere to produce a diffraction pattern.
Construct a pinhole projector to introduce participants to the basic properties of light. This tool can then be used to view eclipses or other bright sources.
