Cómo se juega
- In Explore, drag from a blue contact to add a wire between the battery, bulb and switch. Drag parts to move them and tap the switch.
- Use the parts box to add a second battery or bulb and the test clips, then test a nail, pencil lead or plastic ruler.
- Levels: light the bulb, switch control, find the fault, conductors and insulators.
Unidad del currículo
Primary science, grade 4: electricity in daily life, lighting a bulb, simple circuits, finding faults, conductors and insulators, and switches (Jiaoke edition, grade 4, book 2, unit 2).
Para padres y docentes
Only a 1.5 V cell circuit is simulated, never mains electricity. Mistakes are grouped as open circuit, short circuit, one bulb contact only, switch not in the loop, wrong fault and conductor choices.
Preguntas frecuentes
Why does the bulb stay off when both wires touch the tip?
A bulb has two contacts, the tip at the bottom and the metal screw on the side. Current must go in one and out the other, so they must go to different ends of the battery.
What is a short circuit and why is it dangerous?
A wire joining the two ends of a battery directly lets a very large current flow, so the battery gets hot and can be damaged.
Is pencil lead a conductor?
Yes. The graphite conducts electricity, but less well than metal, so the bulb is dim.
