Electricity is a kind of energy that can make light, heat, sound and movement.
It powers your lights, your fan, your TV and even your tablet right now!
Tiny pushers called electrons move along wires. When they keep moving in a loop, we say electricity is flowing. 🌀
In this Spark, you will switch on a bulb, build a circuit, and become an electricity detective. Tap Next to start! 👉
Electricity needs a full loop
For a bulb to light up, electricity must travel all the way around — from the battery, through the wires, through the bulb, and back. This path is called a circuit.
A switch is a little gap we can open or close. Tap the switch below to close the loop!
Right now the switch is OPEN — the loop is broken, so the bulb is off.
The 4 jobs in a circuit
Every simple circuit has a few important parts. Tap each card to reveal what its job is! 🔎
🔋
Battery
The energy source. It pushes the electricity around the loop.
➰
Wires
The path that carries electricity from part to part.
💡
Bulb
A load. It uses the energy and turns it into light.
🔘
Switch
A gate. Open = off, closed = on. You control the flow!

What lets electricity pass?
Conductors let electricity flow through them (most metals). Insulators stop electricity (plastic, rubber, wood).
Tap a thing below, then tap the correct box to sort it. 🧲
✅ Conductors

🚫 Insulators
electricity blocked
First tap a thing, then tap a box. Selected: none
More batteries = brighter bulb
Add more batteries and you give electrons a bigger push, so the bulb glows brighter. Slide to try it! 🎚️
🔋1
Try sliding to 3 batteries for the brightest light!
⚠️ Tip: too many batteries in a real bulb can burn it out — engineers pick just the right amount.
Be safe with electricity 🛡️
Small batteries are fine to explore, but the electricity in wall sockets is very strong and can hurt you. Tap each rule to learn it.
🔌
No poking sockets
Never put fingers or objects into wall sockets.
💧
Keep it dry
Water carries electricity. Keep plugs away from water.
🧑🦰
Ask an adult
Always check with a grown-up before plugging things in.

Brilliant work, electricity detective!
Here's what you sparked today:
⚡ Electricity is energy made of tiny electrons that flow.
🔁 A circuit must be a complete loop to work.
🔘 A switch opens or closes the loop to turn things off and on.
