I am in grade 8, and I am one of the best students, and I am having a little bit of trouble with this, I doubt that 2nd graders would understand how to make a lie detector and, about transistors, PN Junctions, etc. When I was in grade six in a school that is harder than normal, I started learning about electronics, like how to connect two wires to a battery and then to a light bulb, and I felt like a scientist, lol. But I really don't think that second grader would know this, they barely know how to read. Anyways, please help me with my questions.
Thank You!!!!
