- Interactions between any two objects can cause changes in one or both.
- Materials that allow electricity to flow are conductors; those that do not are insulators. (PS3.A)
- Electrical circuits require a complete loop through which an electrical current can pass. (PS3.A)
- An open circuit is an incomplete electric pathway; a closed circuit is a complete pathway. (PS3.A)
- Energy can be moved from place to place by moving objects or through sound, light, or electric currents.(PS3.A)
- Electrical circuits are a flow of electricity with a current.
- Electrical circuits are used in their daily life to power devices/machines.
- Conductors allow the flow of electricity and insulators block the flow of electricity.
- Switches complete a path for the electric circuit.
