By dropping a magnet through a copper tube, participants learn how the magnetics fields can still interact with nonmagnetic materials.
Participants learn the everyday science of electric motors in this fun and engaging workshop activity.
This demonstration dramatically shows how not just the strength of a material, but how it is designed, is important when withstanding forces.
Fabric of the Universe Part 2
After completing Part 1, explore solar system formation, tides, and planetary rings using a spandex sheet.
Impulse on Eggs
Participants learn about impulse by building vehicles to drop eggs in.
Off-Grid Phone Charger
Constructing this simple and inexpensive portable cellphone charger provides an introduction to soldering and electronics.
Practically, these units can be used for charging in regions of the world where grid electricity is not readily available.
Variable Index of Refraction
A sugar-water solution is used to create a liquid with a variable index of refraction. Participants learn about solutions, gradients, and refraction.
Students learn about glass, how glass is formed, and under what conditions that can occur.
Polarization of Light
This demonstration explains transverse waves and some surprising properties of polarizers.
By constructing a simple straw “oboe,” participants learn about sound waves and closed pipe resonance.
