Level 1

Eddy Currents

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. 

Ferrofluids

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.

Hair Diffraction

Participants use a hair to show how light can interfere to produce a diffraction pattern.     

Pinhole Projector

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.
