  • Electricity is powerful — it helps bring robots to life! But it must be handled safely. To build and use robots properly, you need to understand which materials allow electricity to flow and how to protect yourself and your circuits.

    • 🔌 What Are Conductors?

      Conductors are materials that let electricity flow easily — like copper, aluminum, iron, and saltwater.

      🧠 Think: Conductors = Highway for electrons

      🪙 Fun fact: The shiny copper wire inside a charger is a great conductor!

    • 🚫 What Are Insulators?

      Insulators are materials that stop electricity — like rubber, plastic, dry wood, and glass.

      🧠 Think: Insulators = Wall for electrons

      🔌 Plug wires are covered in plastic to keep you safe from electric shocks!

    • 🦺 Why Safety Matters in Robotics

      Robots use electricity, so be careful! ⚠️ Shocks, short circuits, or burns can happen.

      Quick Safety Tips: Turn off power before wiring, use insulated tools, and never touch bare wires.

      🧪 Mini Experiment (with adult help)

      Test materials like spoon or rubber band with an LED circuit — if it lights up, it's a conductor!

      🌍 Cool Fact

      Electric eels create electricity to shock prey — nature’s own robot power!
