Instructions: Work through the activities in order. Read each question carefully and write your answers in the boxes. Use the examples and word bank to help you remember how simple series circuits work.

1

Electrical Appliances Around Us

An electrical appliance uses electricity to do a job. Choose the best answer for each question. Think about what the appliance does and whether it needs electricity to work.

1. Which appliance keeps food cold?

2. Which appliance is used to boil water?

3. Which appliance can make a room brighter?

4. Which appliance is used to clean carpets by sucking up dust?

5. Which appliance is used to wash clothes?

2

Build a Simple Series Circuit

A simple series circuit needs a complete path for electricity to flow. Use the word bank to complete each sentence. Each word is used once.

Word bank: cell, wires, bulb, switch, complete

1. The ___ provides electrical energy for the circuit.

2. ___ connect the parts and provide a path for electricity.

3. A ___ lights up when electricity flows through it.

4. A ___ can open or close the circuit.

5. For a bulb to light, the circuit must make a ___ path.

3

Is the Circuit Complete?

In a series circuit, all the components are connected along one path. A bulb lights only when that path is complete. Read each description and write whether the bulb is ON or OFF.

1. A cell, wires and a bulb are joined in one unbroken loop. Bulb:

2. There is a gap between one wire and the bulb. Bulb:

3. A switch is closed and every wire is connected. Bulb:

4. A switch is open, leaving a gap in the circuit. Bulb:

5. A wire is disconnected from one end of the cell. Bulb:

4

What Does the Switch Do?

A closed switch completes the circuit; an open switch breaks the circuit. Choose the best answer for each question.

1. What happens when a switch closes a complete circuit?

2. What does an open switch do to the circuit?

3. A bulb is off because the switch is open. What should you do to complete the circuit?

4. Why does a bulb go off when the switch opens?

5

Conductors and Insulators

A conductor lets electricity pass through it. An insulator does not let electricity pass through easily. Write “conductor” or “insulator” for each material.

1. Copper

2. Plastic

3. Iron

4. Rubber

5. Aluminium

6

Choose a Safe Circuit Material

Use what you know about conductors and insulators. Choose the best answer for each question. Remember that the metal inside a wire conducts electricity, while the plastic coating helps keep people safe.

1. Which material would be suitable for the metal part of a connecting wire?

2. Why is the outside of many wires covered in plastic?

3. Which material is an electrical conductor?

4. Which material is an electrical insulator?
