Matter

Matter explained in an easy to understand way:

Imagine trying to fit all your groceries into a single, small shopping bag. Just like how each grocery item takes up space and adds weight to the bag, matter is anything that occupies space and has mass. The groceries represent different types of matter, each with its volume (space it takes up in the bag) and mass (how heavy it makes the bag), illustrating how matter is essentially everything that has volume and mass.
