Snap Circuits Jr. Projects #7 & 8 – “Light Emitting Diode” Demonstrated and Explained

Join me as I explore Snap Circuits Jr. Projects #7 and #8 to learn how Light Emitting Diodes (LEDs) work! In this hands-on STEM video, I demonstrate and explain how LEDs allow current to flow in only one direction and why resistors are necessary to protect these sensitive components. Starting with Project #7, I build a simple circuit to illuminate an LED using a battery, resistor, and slide switch. In Project #8, we reverse the LED to show that it no longer lights up—highlighting the one-way behavior of LEDs. These two engaging experiments help young learners understand basic electronics, current flow, polarity, and the practical importance of resistors in protecting components. Great for students, parents, teachers, and budding engineers looking for an easy and fun introduction to electrical circuits. 🔔 Don't forget to like, comment, and subscribe for more Snap Circuits and educational STEM videos!
