What I learned about Matter

Matter is anything that has mass. Mass is the amount of matter in an object. Everything is matter. The difference between mass and weight is that weight is the amount something weighs due to gravity. For example, and average adult on earth can weigh about 130 pounds, but on the moon or another planet they can weigh more or less depending on the size, there is no less of the person but due to gravity they weigh more or less. Matter can take a form of a solid, liquid, or gas. Atoms of a solid are packed tightly together. The atoms of a liquid move close together. The atoms of a gas move freely. Matter is made up of atoms.That is what I learned so far, but hope to earn more!
