Models
Objective:
Learners understand the concept of models as simplified representations of complex realities, learn about their uses and limitations, and apply this knowledge to a selected model.
Content and methods:
The worksheet introduces the topic of a selected model and its basic characteristics. Using a case study, the pupils analyse and describe how the model works and its assumptions. They also critically reflect on the model's significance and limitations.
Competencies:
- Understanding and describing models and their elements.
- Critical thinking and reflection on the significance and limitations of models.
- Applying theoretical knowledge to practical examples.

Introduction
Today, you will take a closer look at a model.
Models simplify complex realities – this can be helpful, but it also has its disadvantages. That is why you will not only describe the model, but also critically examine it.
Understanding Models
Models are simplified representations of reality. They help us understand complex situations by reducing the details to what is most important. Imagine it like shrinking a big map to a handy city plan. This makes it easier to navigate without needing to know every detail of the surroundings.
Models are used to analyze, explain, or predict processes. For example, if you want to know how the price of apples changes when the weather is bad, a model can help you understand these relationships and analyze how different factors are connected.
A model consists of various elements that together create a picture of reality. It's important to ensure these elements fit well and represent the key aspects of the problem being studied. Clearly defining the assumptions made in the model is crucial. These assumptions are the foundations on which the model is built and operates.
A model should be simple and clear, yet detailed enough to answer important questions. It's also important to regularly check if the model is still current and accurate. This can be done by comparing predictions with actual events.
Overall, models help us understand the world better and make informed decisions. They are tools that support us in planning for the future and being prepared for changes.
📝 Look at the model and then answer the questions.

Descriptions of models
First explain which actors or elements appear in the model. Then describe how they are connected to each other – i.e. what relationships or effects exist. Also state the assumptions on which the model is based. Make sure you explain clearly and objectively what the model shows – and what it does not show.
The High School Concert Conundrum
Alex and their friends are excited about the upcoming concert of their favorite band playing in town. The tickets are selling fast, and there's a buzz at school about who managed to grab them. However, Alex faces a dilemma. They have saved up some money from their part-time job, but it's not quite enough to cover the cost of both the ticket and transportation to the venue. Now, Alex must decide: should they spend all their savings to attend the concert, or should they save some for future expenses, like the upcoming school trip?
Meanwhile, Alex's friend Jamie, who runs a small business selling homemade jewelry online, sees the concert as an opportunity. Jamie plans to create special band-themed accessories to sell to fans attending the event. They hope to use the concert as a way to boost their business and earn some extra cash. Jamie wonders if investing in more materials to make extra jewelry will pay off, or if the risk might leave them with unsold stock.
The town's local businesses, like the pizza place near the concert venue, are also gearing up for the event. They expect a surge in customers on the concert night, and the owner is considering hiring extra staff to handle the crowd. The excitement builds as everyone prepares for the concert, but it's clear that decisions made by Alex, Jamie, and the local businesses will affect their future plans and finances.
In this scenario, students can explore how choices made by individuals and businesses influence the flow of money and goods in the community, using the circular flow model as a guide. What should Alex do? Will Jamie's business thrive? How will the local pizza place manage the concert night rush?
Information
Models simplify complex relationships so that we can understand them better. However, they never reflect reality in its entirety. People often act differently than models assume – for example, they do not always act rationally. Models should therefore be critically questioned and should not be used as exact representations of reality, but rather as aids to thinking.
