Okay kiddo, imagine there are two hands - a right hand and a left hand. They look almost the same but if you compare them, you will notice that they are mirror images of each other! This is what we call chirality.
Now let's take this idea to the particle world. Some particles, like electrons, also have chirality. They can only spin in one direction or the other! Just like you can only wear a left or right-handed glove on the corresponding hand.
Scientists have made something called a chiral model, which helps them study the behavior of these chirally sensitive particles. The model uses complex equations to describe how particles with different chiralities interact with each other.
So in simple terms, a chiral model helps scientists understand how these particles move and interact based on their chirality - just like you can only wear a certain glove on a certain hand!
