Fascinating Fact:

A spreadsheet model uses formulas to show how changing one value can affect other values, like profit changing when costs rise.

In KS3 ICT, models are used to represent real situations so you can explore patterns and outcomes safely. You might use a spreadsheet, a diagram, or a simulation to test choices, spot risks, and plan improvements.

Key Terms

Model: A simplified representation of a real system or situation used to explore what might happen.
Simulation: A model that imitates real behaviour over time, often used to test different conditions.
What-if analysis: Changing inputs to see how results change, so you can compare options and make decisions.

Frequently Asked Questions (Click to see answers)

What is a model in ICT for KS3?

In KS3 ICT, a model is a simplified version of a real situation that helps you understand it and predict outcomes, such as planning costs or testing different choices.

Why do we use models instead of real-life testing?

Models are used because they are safer, cheaper, and quicker than real-life testing. They let you try ideas without wasting resources or causing real-world problems.

What are the limits of ICT models and simulations?

ICT models can be limited by missing data, assumptions, and simplified rules. If inputs are wrong or unrealistic, the results can be misleading even if the model runs correctly.
