Opening your next discovery…
Relate voltage, resistance and current in an ideal circuit. Model assumptions remain visible.
Each step connects a clear learning objective with something you can investigate.
Build a complete conducting path. Observe how an open switch, an absent component or a changed resistance affects the model.
Identify a closed circuit and explain how the battery, bulb, wires and switch work together.
Bring your curiosity. These introductory experiences provide their own guidance, and you can revisit any step.
Choose one experiment. Describe what you predicted, what you changed and what you observed. Then explain why the outcome makes sense.
Which observation supports your explanation? What would happen if you changed a different variable?
Find an everyday situation that follows the same idea. Explain where the laboratory model helps, and where the real situation is more complicated.
