Coro's Spark Adventure: Electricity for Kids

By Rithik Krisna · Ages 6–10 · Coro's Electronics Tutorials

Join Coro on a bright first adventure into electricity. Kids discover what a battery does, how a circuit makes a loop, how switches, bulbs and LEDs work, which materials let electricity through — and how to stay safe.

What young makers will try

  • Light an LED
  • Make a simple switch
  • Quizzes after each short chapter, plus a colour-in certificate

Projects are designed to be done with a grown-up. Use only small batteries — never mains sockets.

Coro's Magnet Mission: Magnets and Motors for Kids

By Rithik Krisna · Ages 6–10 · Coro's Electronics Tutorials

Coro's next mission explores magnets, poles and the compass, how electromagnets work, and how magnets make motors spin.

What young makers will try

  • A magnet switch that lights an LED
  • A magnet sorter
  • A simple motor

Projects are designed to be done with a grown-up. Use only small batteries and magnets — keep small magnets away from young children who might swallow them.
