Okay kiddo, so you know how bones are very strong and hard, right? They help us move and stand up straight. But sometimes, when we fall or get hurt, a bone can break into two or more pieces. That's called a fracture.
Now, this can also happen in other parts of our body like our teeth or even some parts of plants and animals, called biological materials. When these materials get hit or bend too much, they can also break or fracture.
But, unlike bones, biological materials are made up of smaller parts called atoms and molecules. When there's a fracture, these smaller parts can get disturbed or separated from each other. And this can make the material weaker and more prone to breaking again.
Scientists study these fractures to find out how to make stronger materials, like stronger bones or sturdier plant stems. They also study how to prevent fractures from happening in the first place. Like wearing a helmet when we ride a bike or making sure we don't put too much weight on thin branches when climbing a tree.
So, that's what a fracture of biological materials is all about. It's when a part of a living thing gets broken because it couldn't handle a certain force, and scientists are studying how to make it stronger or avoid it from happening.
