🧪 Kitchen Conductors

primary-5 · Ages 9–12 · 🏠 Safe at home

Objective: Discover which kitchen materials conduct electricity.

🔒 Safety Notice: Ask an adult to supervise. Do not taste any experiment materials. Do not use dangerous chemicals. Follow the instructions carefully and wash your hands afterwards. Use only a small battery. Never use mains electricity.

🔮 Step 1 — Predict first!

Your prediction

Predict which materials will make the bulb light.

Write your best guess (scientists call it a hypothesis):

🧰 Materials

A small battery, a bulb in a holder, 3 wires, a metal spoon, a wooden spoon, a plastic spoon, a coin

📋 Instructions

1. Build a simple circuit with the battery, bulb and two wires.
2. Leave one gap in the circuit.
3. Put each spoon (or coin) across the gap and watch the bulb.

⚙️ The variables

🔧 What we change

The material across the gap

📏 What we measure

Whether the bulb lights up

⚖️ What stays the same

The same battery and bulb

📊 Step 2 — Collect your data

Enter your own measurements below — the chart draws itself as you type. If your experiment does not have measurements, record what you saw in the notes box.

🔍 Step 3 — Prediction vs observation

What actually happened? Compare it with your prediction:

💡 The science behind it

Metals are conductors — electricity flows through them easily, so the metal spoon and coin light the bulb. Wood and plastic are insulators, so the bulb stays off.

🏁 Conclusion

You classified materials into conductors and insulators using evidence — exactly like an electrical engineer!

🚀 Extension challenge

Why are electric wires made of metal inside but plastic outside?

🧑‍🏫 Teacher notes

Small batteries only; never experiment with wall sockets.
