The Electric Squeeze
Source Institutions
In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.
Control the Flow
Source Institutions
In this activity about electricity, learners build and test a paper clip switch to turn on a light bulb.
Circles of Magnetism IV
Source Institutions
In this activity related to magnetism and electricity, learners observe as two parallel, current-carrying wires exert forces on each other.
Circles of Magnetism I
Source Institutions
In this activity related to magnetism and electricity, learners create a magnetic field that's stronger than the Earth's magnetic field.
Carrying Charges: Testing for Conductivity
Source Institutions
Learners are challenged to create solutions that conduct electricity and make a buzzer buzz (or an LED light up).
Magnetic Suction
Source Institutions
In this activity about electricity and magnetism, learners discover how a doorbell works. A coil of wire with current flowing through it forms an electromagnet that acts similar to a bar magnet.
Hand Battery
Source Institutions
In this activity about chemistry and electricity, learners form a battery by placing their hands onto plates of different metals.
