Strengths & Limitations of Models
Science: KS3, topic 4.1.1
Strengths and Limitations of Models
Models in Science help us understand phenomena that would otherwise be difficult to visualise. Models are used to help us understand the concepts. Models do not have just to be physical models.
Strengths of models
- Models help explain hard ideas.
- Patterns can be seen.
- Help us remember key information.
- Models become the building blocks of more scientific discoveries.
More strengths of models
- Another strength is helping us to represent ideas that would otherwise be hard to explain.
- For example:
- We can model things that are too big to see – such as the solar system.
- We can model things that are too small to see – such as the particle model.
Limitations of models
- Models are simplified versions.
- Models can be interrupted in many different ways.
- Models do not always cover everything in detail and can miss vital details.
- Models are approximations.

Select the correct statement in each pair
Scientists made a model of the solar system hundreds of years ago. Even though parts of it were later found to be incomplete, newer discoveries were built using it as a starting point. Which strength of models does this show?
