Record Your Observations

As you explore Ohm's Law Circuit, record what you notice:

  1. Starting conditions: What are the initial settings?
  2. Changes: What happens when you adjust the variables?
  3. Patterns: Do you notice any patterns or relationships?
  4. Evidence: What specific data supports your observations?

Predict • Observe • Explain

Predict

Before running the simulation, predict: what do you think will happen to Ohm's Law Circuit when you change the variables?

Observe

Run the simulation with different settings. Record the patterns and relationships you see.

Explain

Compare your observations with your prediction. Use scientific vocabulary to explain why Ohm's Law Circuit behaves this way.

Key Concepts

Variables

Changing one variable while controlling others helps us isolate cause and effect in Ohm's Law.

Patterns

Look for repeatable patterns in the data — they reveal the underlying scientific principles.

Models

This simulation is a model — a simplified representation that helps us understand Ohm's Law.
