Learning circuitry is now as intuitive as using a pen. Our non-toxic, conductive ink enables you to draw freeform, working circuits and connect magnetic modules between your drawings to activate lights, sounds, motors and more! Geared towards fundamental electronics and physics lessons, the complexity of the concepts ranges from beginner to advanced circuitry. This kit is an accessible and fun way to introduce circuitry to classes of 25-30 elementary through high school students.Details:STEM learningFor use with class sizes up to 25-30 studentsFor ages 8 and upContents:50 LEDs50 Connector Cables30 Circuit Scribe Conductive Ink Pens25 Switches25 9V Battery Adapters25 Blinkers25 Multi-Colored LEDs25 Dimmers25 NPN Transistors25 Steel Canvases25 Motors & Foam Wheels5 Light Sensors5 USB Adapters5 Buzzers5 Double Switch5 Dials5 DIY Connectors1 Inventor's Notebook1 Jumper Sticker Sheet
