## Science

Unit 2 - Designing Alarm Circuits

(September 19-October 28)

· the flow of electrons can take a variety of paths to complete a circuit.

· electrical energy can be transformed into light or motion, and can produce thermal energy.

· a switch can be used to control whether a circuit is closed or open and uses mechanical energy.

· when an electric current flows through a wire from a battery, it produces a magnetic field.

· electrical energy moves through materials that are conductors (metals). Insulators (rubber, plastic, wood) do not conduct electricity well.

· humans can harness electrical energy to do useful things.

· a circuit must be closed in order for electricity (current ) to move through it.

Critical Vocabulary

• circuit
• conductor
• electrical energy
• insulator
