Electricity — Building a Simple Circuit

Electricity becomes real when the bulb lights. A broken circuit stays dark — the completeness is the control. The child learns that current needs a closed path, then explores what allows that path.

• Framework: Montessori
• Unit: Cultural Studies
• Learning area: Physical Science
• Level: Ages 7-9

Objectives

• Build a simple closed circuit with battery, wire, and bulb
• Understand that electricity flows in a complete loop
• Distinguish conductors from insulators
• Add a switch for on/off control

Materials

• 1.5V battery, battery holder
• Small LED bulb or flashlight bulb with holder
• Insulated wire with alligator clips
• Simple switch
• Various materials to test as conductors/insulators (copper, aluminum, plastic, rubber, paper, water)

Instructions

1. Connect the battery to the bulb directly with two wires. 2. The bulb lights. 3. Break one wire — bulb goes out. Why? 4. Discuss: electricity needs a complete loop. 5. Add a switch; flip to turn the bulb on/off. 6. Substitute different materials for a wire: copper (bright), aluminum foil (bright), plastic (no light). 7. Classify: conductors (metals, salty water) vs insulators. 8. Draw circuit diagrams. 9. Research electricity in the home.

Educator tip

Use LED bulbs — they're safer and more forgiving. Adult supervises any setup near water.

Assessment

Note correct circuit assembly, identification of conductors vs insulators, and circuit diagram accuracy.
