Life as we know it would not be possible without electric transformers, so there are fewer more pertinent topics for your eager young engineers. An astounding amount of background information is provided to help you develop a lecture on...

Eat up a resource on using food to power electrical devices. Future engineers first experiment with different fruits and vegetables to determine the amount of electrical energy they provide. Based on the data, they design and create an...

Put those old holiday lights to good use. Individuals use a section of ornamental lights to create electric circuits. If the lights glow, it's a success; otherwise, it's time to try again!

When you think electric circuits, your pencil probably isn't the thing that comes to mind. A simple experiment lets learners test whether the graphene in pencil lead is a conductor or an insulator. If the LED bulb lights up, a conductor...

Orange you glad you can make circuits using fruit? Young electricians learn about electric circuits and electricity. As part of the instructional activity, they build a circuit with an orange and then with a banana.

Light up a locker for a more festive hallway! Scholars learn about electric currents, LEDs, and switches, then experiment with their own circuits. They use the circuits to design and build locker decorations that light up when turned on...

In pairs, learners build a piezoelectric generator from readily available electric components in the second and final installment of the two-part series. Tapping the piezoelectric element produces enough electricity to light an LED....
