4 What s the Matter? Have you ever noticed how some things take up a lot more space than others? Is that because they matter more? No, it s because they have more matter! Matter is a substance, or object, that has mass, takes up space, and can be changed by energy. Everything around you is made up of matter. All matter is made up of atoms, which are too small to be seen with your eyes, or even a regular microscope. Mass is how much matter an object has. We measure mass in grams. More Matter Less Matter Does it Matter? WORD BANK atoms matter space mass grams Use the word bank to fill in the answers below. Some words may be used more than once. 1. What has mass, takes up space, and can be changed by energy? 2. The amount of matter an object has is called what? 3. We measure mass in what unit? 4. What is everything around us made of? That s a That s alot of Matter matter! 5. What do all objects take up? 6. All matter is made up of. 8

5 As a Matter of Fact Not all matter is the same. Matter is usually found in one of four ways: solids, liquids, gases, and plasmas. These are called the states of matter. Matter changes from one state to another state when energy, like temperature or pressure, is applied to it. Matter becomes more active as temperature increases, and less active as it decreases. Objects, or substances, can only move from one state of matter to another if energy is added or taken away. The movement of matter from state to state does not change the substance, just the physical state of the substance. Ice, water, and water vapor are still the same substance, just in different states. They re all water! I m Melting! Unscramble the letters below to find words associated with matter. Use the word bank if you need help. 1. taetmr e 2. ilodss s 3. iuilqsd u 4. saseg s 5. smlaspa p 6. upmetrteaer p e 7. spyichla y 9 WORD BANK plasmas gases liquids solids temperature physical matter

6 I want to be a rock star! Rock Solid! Have you ever tried to break a rock? It s not easy. That s because a rock is a solid. Identifying solid matter is easy. It s the only state of matter that is hard and holds its own shape. That s because the molecules in a solid are packed together. The closer they are packed, the harder the solid. Atoms in a solid do not move around much, unlike those in liquids and gases. They re stuck together in an orderly way! A solid can become a liquid by melting when heated. Or, it can become a gas through a process called sublimation. Solids can be stretchy, or elastic. Rubber bands are solids. A solid s shape can also be molded or changed. When a solid is made up of more than one substance, it s called a mixture. Most solids, like rocks, plastics, and glass, are mixtures. Crystals are solids made up of a pure substance that forms slowly over long periods of time. Can you think of any pure solids? Here s a hint: Women love to wear them, because they sparkle!
