Sample questions

A few real prompts from the game to help you choose an activity for your class.

01
What does a simple electrical circuit need?
- a battery, wires and a bulb
- a bulb and just one wire
- wires, a bulb and a switch
Read the explanation
It needs a power source, wires and a device - all three - before it works.
02
What happens to the bulb if a wire breaks?
- it flickers
- it goes out
- it gets brighter
Read the explanation
A circuit must be complete for current to flow; a break anywhere and the light goes out.
03
What is the conducting core of a wire usually made of?
- plastic
- rubber
- copper
Read the explanation
A wire's core is usually copper, because it conducts electricity well and bends easily; plastic and rubber are the insulating cover outside.

Game teaching guide

What children will practise

Simple circuits: the parts of a circuit, the need for an unbroken loop, copper wire cores, insulation, what a switch does and electrical safety. It matches indicator ว 2.3 ป.6/1 (parts and functions of a simple circuit), a Grade 6 topic.

What's in the worksheet

6 questions, multiple choice with three options each - A simple circuit needs a battery, wires and a bulb - If a wire breaks the bulb goes out - Wire cores are copper and covered in rubber because rubber insulates - A switch breaks or completes the circuit; never touch electrical devices with wet hands

How to use it in class

Best after children have built real circuits with a battery, wires and a bulb, about 5-6 minutes, solo. In question 1 the distractor wires, a bulb and a switch looks complete but has no power source: let children try it without the battery. Questions 4 and 6 lead into safety talk, such as telling an adult about a damaged cable at home rather than fixing it. You can link it to a class and record it in the gradebook. Question 4 says wires are covered in rubber, but most household cable today is insulated with PVC plastic; tell children both rubber and plastic are insulators.

Common sticking points

- Question 1: choosing wires, a bulb and a switch because every room at home has switches. Point out that without a battery there is no electricity. - Question 6: choosing it is fine to unplug by pulling the cord, a common habit. Explain that pulling can break the wires inside and is dangerous. - Question 3: choosing plastic or rubber because they only see the outside of a cable. Strip an old cable to show the copper core.
