Lesson Overview

Students work in pairs to build and test a simple circuit using a battery, wires, and a bulb or LED. The mini-project helps them understand how electricity flows in a closed circuit and what causes a circuit to work or fail.

Learning Objectives

  • Identify the main parts of a simple electric circuit.
  • Build a working closed circuit using provided materials.
  • Explain why a circuit must be closed for electricity to flow.
  • Test and improve a simple circuit design through trial and error.

Materials Needed

  • AA batteries or battery packs
  • Battery holders
  • Connecting wires with clips
  • Small bulbs or LEDs
  • Bulb holders if available
  • Switches if available
  • Student recording sheet
  • Pencil
  • Optional: tape

Vocabulary

TermDefinition
CircuitA complete path that electricity follows.
Closed circuitA circuit with no breaks, allowing electricity to flow.
Open circuitA circuit with a break, so electricity cannot flow.
CurrentThe flow of electric charge through a circuit.
BatteryA source of electrical energy.

Lesson Sequence

Introduction3 minutes
Teacher Actions

Show a battery, wire, and bulb. Ask: 'What do you think we need to light the bulb?' Introduce the project goal: build a circuit that works.

Student Actions

Observe the materials, predict what might make the bulb light, and share ideas.

Build and Test10 minutes
Teacher Actions

Model how to connect the battery, wires, and bulb safely. Circulate to support groups as they build, test, and revise their circuits.

Student Actions

In pairs, build a simple circuit, test whether the bulb lights, and make changes if it does not work.

Project Share4 minutes
Teacher Actions

Ask a few pairs to show their circuit and explain what made it work. Highlight closed circuit and open circuit.

Student Actions

Present their circuit and describe one problem they solved or one change they made.

Wrap-Up3 minutes
Teacher Actions

Review the key idea that electricity needs a complete path. Collect quick answers to check understanding.

Student Actions

Answer exit questions and reflect on what they learned.

Support

  • Provide a partially built circuit for students who need a start.
  • Use larger diagrams or color-coded wire labels.
  • Pair supportive classmates with students who need help.
  • Allow students to test one connection at a time.
  • Give sentence starters such as 'The bulb lit because...'

Challenge

  • Ask students to add a simple switch if available.
  • Challenge students to compare an open circuit and a closed circuit.
  • Ask students to explain why the bulb does not light if one connection is removed.

Checks for Understanding

  • Can the student identify the battery, wire, and bulb?
  • Did the student build a closed circuit?
  • Can the student explain why the bulb lights or does not light?
  • Can the student use the words closed circuit or open circuit correctly?

Closure

Ask students to complete the sentence: 'A bulb lights when the circuit is __________.' Revisit the main idea that electricity needs a closed path.

Assessment

Formative assessment through teacher observation of the build process, student explanations during sharing, and the exit question at the end of class.

Homework

Draw and label a simple circuit at home. Write 2-3 sentences explaining the difference between an open circuit and a closed circuit.
