PhET Circuit Simulation Worksheet

What is the main purpose of building a simple circuit with a battery, wire, and bulb in the PhET simulation?

• To observe how electric current flows

• To measure temperature changes

• To test different types of batteries

• To create a chemical reaction

What happens when you break the circuit (open it)?

• The light turns off

• The bulb gets brighter

• The battery recharges

• The wires melt

What is moving through the wires in a closed circuit?

• Electrons

• Protons

• Neutrons

• Atoms

What should you do if the bulb doesn’t light up in your circuit?

• Fix the circuit so it’s closed

• Replace the bulb with a new one

• Add more batteries

• Remove the wires

Why does the light bulb turn off when the circuit is open?

• Electrons stop moving

• The wires are too long

• The battery is too strong

• The bulb is too small

What happens when you use more coils (wraps) of wire in the electromagnet?

• The magnetic strength increases.

• The nail melts.

• The battery stops working.

• The wire breaks.

What happens if you increase the battery voltage in the electromagnet?

• Electrons move faster and magnet strength goes up.

• The wire turns into a permanent magnet.

• The nail dissolves.

• The battery lasts longer.

When electricity flows, it can make a __________.

• magnetic field

• sound wave

• chemical reaction

• light beam
