A membrane is a thin layer or surface that covers or separates things. For example, our skin is a membrane that covers our bodies. In science, membranes are important because they help control what goes in and out of cells or organs. They are also used in everyday things like water filters and food packaging. So, if you hear someone talking about a membrane, they might be referring to a thin layer that separates or covers something.
