This is a simulation, not a quiz. You answer by trying things and watching what happens.
Our question
What controlled comparison will help you use light and shadow observations to predict what changes when an object or light source moves?
Getting the simulation ready…
1Change one thing
2Say what will happen, then run it
3Finish: say what you found
What counts as evidence
Select the measured comparison that directly addresses the prediction.
Name the changed condition, cite one result, and connect it to this goal: Use light and shadow observations to predict what changes when an object or light source moves.
Your controlled comparison, measured result, revised model, and transfer claim become inspectable scientific evidence.
