This hands on learning kit is perfect for introducing students to the basics of electrical circuits and Morse Code. Engaging for students - allows them to explore and visually understand which configurations result in a successful or unsuccessful current path- all while having fun building their kits! Each kit includes necessary components for building basic parallel and series circuits and demonstrating the basic concept of Morse Code. A simple and classic exploration in how to make a light bulb illuminate. The rule that students should be able to determine is that there must be a path that goes from the negative side of the battery to the positive side of the battery and that there should only be one path through the filament of the light bulb. Additional experiments examine the relationships between the circuits & bulbs the rules in which currents behave within a variety of circuit configurations & what leads to short circuiting. Experiment Guide includes instructions for setting up your circuits safely activity steps discussion topics and follow up questions for students. Kit Includes: D Batteries (2) Insulated Wire 120 Knife Switch Single Contact Key Bulb Holders (2) Battery Holders (2) Miniature Light Bulbs (5) Experiment Guide*Required materials not included: Wire Cutter & Stripper and Multimeter or Voltmeter & Ammeter (used for measuring current behaviors)
