We also had our new Eddy Current demonstration where we drop high strength niobium magnets through different type of materials. 

Moving magnetic fields induce eddy currents in conductive materials, which create a counteracting magnetic field that slows down the motion. The speed of the moving object is affected by the strength of the magnetic field and the electrical properties of the conductor. At low speeds, the force is proportional to the velocity; at high speeds, the effect is reduced by the opposing magnetic field created by the eddy currents, and the force may become less predictable. 

We have basic electronic kits available for loaning to classrooms. The kits have resistors, LEDs, batteries, breadboards and switches to learn about circuits and Ohm's law.
