1. Imagine

Instructions (Part I): Obtain your circuit materials and analyze the below images. Pay close attention to how the long and short ends of the LED are aligned with the positive and negative sides of a battery. 

Instructions (Part II): Click here to view a short video that demonstrates how to make a simple circuit with a switch. Repeat the process shown in the video using your materials. 

Instructions (Part III): Keeping your circuit from “Part II” in mind, imagine a method for creating a circuit capable of lighting two LEDs, with a switch that only turns off one LED.  Reflect on this challenge and make a clear sketch of your idea on a sheet of paper.
