Let your students explore the nature of science and use the science practices when they build this paper circuit and explore the rules that govern which LEDs will light at the same time and which ones will not. Extend their learning into constructing an explanation as you challenge them to provide a claim, supported by evidence, and including scientific reasoning.
Perplexing Circuit – Hopefully you don’t need to use this video because students are building these themselves and exploring how they work. This is here just in case you want to use it as a hook initially.
Perplexing Circuit Build Directions – demonstrates how to build the circuit and calls out some pitfalls to beware of while constructing the circuit.
