To successfully tackle the modelling and problem-solving tasks in Unit 4, it’s essential to adopt a structured approach that goes beyond typical exam question-solving. Here’s how you can address each requirement:

1. Analyse:
   • Break down the problem into smaller, manageable parts.
   • Identify the variables and constants involved.
   • Understand the relationships between different components.
2. Comment (what the graphs are showing):
   • Describe the trends and patterns observed in the graphs.
   • Point out any significant data points, peaks, troughs, or anomalies.
   • Mention any correlations or lack thereof.
3. Interpret (the results):
   • Explain the significance of the results in the context of the problem.
   • Discuss what the results mean in practical terms.
   • Relate the findings to real-world applications or implications.
4. Evaluate (the models):
   • Assess the strengths and weaknesses of the models used.
   • Consider the accuracy, reliability, and validity of the models.
   • Discuss any assumptions made and their impact on the results.
5. Explain:
   • Provide a clear and detailed explanation of the methods and processes used.
   • Ensure that the explanation is logically structured and easy to follow.
   • Use diagrams, equations, or flowcharts if necessary to clarify complex points.
6. Justify:
   • Provide reasons for the choices made during the analysis.
   • Support your decisions with evidence or logical reasoning.
   • Explain why certain methods or models were preferred over others.
7. Compare (the models):
   • Highlight the differences and similarities between the models used.
   • Discuss how each model approaches the problem and its effectiveness.
   • Evaluate which model performs better and under what conditions.
8. Reflect:
   • Look back on the entire process and consider what was learned.
   • Think about what worked well and what could be improved.
   • Reflect on how the approach or models could be applied to other problems.
