CPO ScienceIntegrated Physics & Chemistry

Developing A Model

How important is electricity to you?

Why do you think the study of electricity falls in physics?

What do we know about electricity already?

Key Questions What is a circuit?

How do we represent a circuit?

How does a switch work?

Developing A Circuit How many ways did you find to

light up the bulb?

Come and draw the four ways

What does each path have in common?

What is unique about the way the bulb is connected in the circuit?

Trail and Error Why do some circuits work and

others do not?

Electric Circuit Set Build one of the four working circuits using the circuit board— Your circuit

should contain: one battery and battery holder, one bulb and bulb holder, and two wire connectors

Drawing A Circuit We have an easier way

to draw circuits— Circuit Diagrams

We use electrical symbols for shorthand— Use these symbols to

draw the circuit you just built

How Does a Switch Work? Add a switch to your circuit

board— You may need a another wire or two

How does the switch control the circuit?

Summary What do you know about electricity?

What is an electric circuit?— How does an electric circuit operate?— How does a switch control an electric

circuit?
