Reflection: Developing a Conceptual Understanding Building Circuits - Section 1: Introduction


While I did have bulb holders and light bulb holders available, I chose not to use them because I wanted to keep the circuit as simple as possible.  According to an article in Science and Children, students tend to mistakenly believe that each component of a circuit somehow contains some kind of innate electricity.  Even in later lessons, once we do get out the bulb holder, I try to show that it really is just a way to create a path from one wire to the bottom of the bulb, and another wire to the side of the base, there is nothing else going.  I only give one wire for a similar reason.  I don't want them to get the idea that a circuit must have two wires to work, just a continuous path.

Objective: SWBAT construct a circuit and explain the differences between a closed circuit, open circuit, and short circuit.

Big Idea: How can you construct a circuit to light up a lightbulb with just one wire and one battery?
