What are theoretical models?

A theoretical model is like a special kind of toy that helps us understand how something really works, without having to touch it.

Imagine you have a big box of Legos. You want to build a tower, but instead of just stacking them randomly, you decide to plan it out first. Maybe you draw a picture or make little sketches of what your tower will look like before you start building. That drawing is kind of like a theoretical model, it helps you figure out how the pieces fit together and what might happen if you change something.

A theoretical model is like a map that shows you the best way to get from one place to another, even though you haven’t walked there yet. Scientists use these maps (or models) to guess how things will behave or what might cause changes in the world around us.

Sometimes, they’re not perfect, just like your Legos tower might look a little different once it’s built, but they help make sense of complicated ideas in simple ways!
