Play dough circuits 2: experiment with electricity Last time, we went through the basics of how to make simple electrical circuits with play dough and light-emitting diodes, now it's time to ...

Simple electrical circuits are super cool, but simple series and parallel circuits are just the foundation of the much, much more complex circuits used in modern electronics.

The result: not only do secondary school students gain a better conceptual understanding of electric circuits, but teachers also perceive the curriculum as a significant improvement in their teaching.

A simple circuit is a chain of different parts with wires and switches which allows electricity to flow around. All electrical appliances use circuits. For electricity to flow correctly, the ...
