The 4th grade is buzzing about electricity and circuits!! After picking up a Squishy Circuit Trunk from the High Desert Museum, the class was off to discover what makes an electric circuit. After formulating questions, collaborative groups used materials consisting of batteries, wires, clips, LED lights, buzzers, motors, conductive dough and insulating dough to discover what makes a circuit work and what can cause a short circuit. Groups wrestled with many issues, but in the end discovered what was needed to make a complete circuit. Groups also discovered why the conductive dough allowed electric current to flow through it (salt and regular tap water containing minerals) and why the insulating dough, stopped the flow of electrons (no salt and distilled water). At this stage of the year, I revel in the ability to present a challenge, then just step back and watch the curiosity and wonder of the students take flight. I love the teamwork and flowering of ideas that transpire in the classroom. I am just a guide, it is wonderful.
