Wires carry electrical messages around a circuit. Your body uses 'nerves' to carry electrical signals around your body. Your body has an incredible network of nerves going all over the body.
Nature's Equivalent:
Your nervous system is a huge network of 'wires' called nerves. Your brain sends electrical signals down these nerves to tell your hand to move or your legs to run, just like a wire carrying electricity to a motor.
💡 Fun Facts
- Copper, the metal used in our wires, is also used by some animals! A horseshoe crab's blood is blue because it uses copper (not iron, like us) to carry oxygen.
- The copper in wires comes from rocks in the ground, a natural material formed over millions of years.
