Synopsis
Circuits are central to how we interact with the world You need a closed path, or closed circuit, to get electric current to flow. If there’s a break anywhere in the path where electricity travels, you have an open circuit, and the current stops flowing — and the metal atoms in the wire quickly settle down to a peaceful, electrically neutral existence. This lesson teaches this concept in a simple and engaging way.
A closed circuit allows current to flow, but an open circuit leaves electrons stranded.
Picture a gallon of water flowing through an open pipe. The water will flow for a short time but then stop when all the water exits the pipe. If you pump water through a closed pipe system, the water will continue to flow as long as you keep forcing it to move.
The movement for including engineering in our NGSS lessons challenges science teachers to teach science lessons that integrate engineering and physical science. The Makey Makey circuit board offers a fun and engaging way to introduce students to the concept of circuits. Students can use everyday object to create circuits.
