Is this STEM game free to use?

Yes. The interactive circuit simulator runs free in any modern web browser, with no login or installation required.

What age group is it for?

It works well for students ages 8 to 14 (upper elementary and middle school) and can be used in class, for homeschool, or by curious kids at home.

What science concepts does it teach?

Learners see how to build a complete series circuit, how a switch controls current, why electricity needs a complete loop to flow, and how the bulb converts electrical energy into light.

Is there a physical kit to build the real circuit?

Yes. The MiniScience Simple Electric Circuit Kit (KITSEC) contains the real battery, switch, bulb, lamp holder and wires so students can build the physical circuit after practicing with the online simulator.

Connection Guide

Instructions:
1. Drag from one contact point to another to connect them
2. The wire strips itself as you pull it
3. Make all three connections below
4. Close the switch to complete the circuit

Required Connections:
• Battery (+) → Switch Input (RED wire)
• Switch Output → Lamp (+) (RED wire)
• Lamp (-) → Battery (-) (BLACK wire)

How Circuits Work

Complete Path: Electricity needs a complete loop to flow. It travels from the battery's positive terminal (+), through wires and components, and back to the negative terminal (-).

Switch Control: A closed switch completes the circuit, allowing current to flow. An open switch breaks the circuit, stopping the flow.

Energy Conversion: The light bulb converts electrical energy into light and heat when current flows through it.
