Opening your next discovery…
Connect observations about water with a simple model. Watershed exploration is a related extension, not a full lesson on changes of state.
Each step connects a clear learning objective with something you can investigate.
Explore how rainfall, vegetation and land cover affect a simplified catchment. Read the diagram as a model, not a forecast.
Make a prediction, control a variable and record evidence. Compare what a model shows with the question it can answer.
Describe how a change in land cover changes the balance between runoff and infiltration within a stated model.
Plan a simple comparison that changes one variable and explain a limitation of its conclusion.
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.
