Simple Circuits Curriculum
This lesson introduces conduction and insulation to prepare students to think about resistance and why the filament in a light bulb behaves differently than the copper conduction wires. The lesson invites students to explore a variety of materials to determine their level of conductivity. There are versions of this lesson in most elementary science programs.
Section 3: Understanding Goals
Subject Matter
- Some materials allow electrons to move more freely along them than others. This has to do with the nature of their bonds.
- Materials that allow electrons to move freely are called conductors. Materials that do not allow electrons to move easily are called insulators.
Causality
- Material types affect current flow, comprising a form of passive causality.
