Your quick start

A model is a place to ask questions.

  1. Choose a lab.Browse by unit or search for a molecule or process.
  2. Predict an outcome.Decide what you expect before changing a control.
  3. Run a fair comparison.Change one variable. Pause and reset to inspect differences.
  4. Explain the pattern.Connect evidence to a mechanism, then try the five concept checks.

Models simplify real systems. Read each lab’s model limits. Separate labs have independent supplies; within the Photosynthesis Connections Lab, both stages share carrier pools.
