Matter

Matter is everything around you that has mass and takes up space. It includes solids, liquids, and gases—like your phone, water, and the air you breathe. Matter is made up of tiny particles called atoms, which are the basic building blocks of all substances. These particles can bond and arrange differently, creating a wide variety of materials and objects. Understanding matter helps us explain the properties of different substances and how they interact, forming the basis of much of science and our everyday experiences.
