It introduces matter as anything that takes up space and has weight, then describes three states—solid, liquid, and gas—based on atomic arrangement.

 \nYou identify useful materials like paper,plastic,and metal by their properties.Metal is heavy,whileplastic is light.Paper is smooth and soft,but wood ishard and rough.Smoothness,weight,and hardnessare a few of the properties of the materials we useevery day.  \nWe identify andchoose manydifferent usefulmaterials like plasticand paper by theirproperties.  \nMetal,plastic,wood,stone,and paper are all  \nexamples of materials.They're substances that peopleuse to make other things.Materials and everythingelse in the world are made of matter.Matter isanything that has weight and takes up space.Theshoes on your feet,the rain outside,the food you eat,and even the air you breathe are all matter.Mattercomes in three forms,or states:solid,liquid,and gas.  \n# Solid,Liquid,or Gas?\n\nKnowing a material's state is one way to help youidentify it.When you see a puddle on the ground,youdon't think it's wood because you know wood isn't aliquid.A material's state is also part of what makes ituseful.Wood is so solid,it's good for building houses.Lemonade would be hard to drink if it weren't a liquid.And air is only breathable because it's a gas.  \nWhat makes solids,liquids,and gases different?It'sthe arrangement of atoms that determines a m","cbCaihv4ACbx8ybq","https://ap.wps.com/l/cbCaihv4ACbx8ybq","pdf",2933996,28,"English","# Comprehension\n## Strategy: Generate Questions\n## Skill: Draw Conclusions\n# Vocabulary Strategy\n## Multiple-Meaning Words\n# Materials at Work\n## Introduction\n## Chapter One: Solid, Liquid, or Gas?\n## Chapter Two: Amazing Materials.\n## Conclusion\n## Glossary and Index\n## Comprehension Check\n# Solid, Liquid, or Gas?\n# Different States of Matter\n# Power of Change","[{\"question\":\"How do you identify useful materials like paper, plastic, and metal?\",\"answer\":\"You identify materials by their properties.
