Electric Circuits are an essential topic that cover the conservation of charge, the conservation of energy, the flow of current and the concept of voltage. In this CoolStuff article, I will describe in greater detail the concepts from the video and explain in greater detail the physics of each of the 9 experiments.
In the Coolstuff video, we demonstrate the fundamentals of electric circuits with this Investigating Electrical Circuits Kit which is more affordable and convenient than most pre-packaged kits for this purpose. The kit is designed to enable inquiry learning, that means that students will be able to do the experiments with almost no guidance from an instructor. Of course, it is helpful for you to be there to check the bulbs and batteries are functioning, but with just the circuit diagrams, a beginner should be able to build all of these set ups.
