Light the circuit · Interactive lab

Your mission path0/4 checkpoints ready

Before you begin, make a prediction.

What must be connected for the bulb to light? What do you expect, and why?

A prediction is a starting idea. You can revise it after exploring.

Change something. Notice what happens.

Preparing your interactive workspace…

Test the idea.

A closed circuit has a 6 V battery and a 20 Ω bulb. What happens to the current if resistance doubles to 40 Ω?

It doubles, from 0.30 A to 0.60 A.It stays at 0.30 A.It halves, from 0.30 A to 0.15 A.

Explain your discovery.

Explain why the bulb goes out when any part of the conducting path is broken.

A researcher’s debrief

Make a claim that answers the mission question.
Use a result from your investigation as evidence.
Explain why that evidence supports the claim.
Name a limitation or an observation that could change your mind.

Use at least 40 characters and include an observation. Your writing is saved as evidence; it is not automatically judged for accuracy.

What counts as completing this lab?

A prediction of at least 8 characters.
At least one interaction with the workspace.
A correct knowledge-check answer, with retries allowed.
A reflection of at least 40 characters.

This records completion of this demonstration. It is not an official grade or a claim of mastery.

Start with a short prediction.
