Grade 5 Science Unit 1 Lesson 1 "Matter is everything around us that takes up space and has weight. It's what everything is made of. Think about the air you breathe, the water you drink, and the desk you sit at – they're all made of matter. Matter can exist in different forms, like solids, liquids, and gases. Solids are things you can touch and feel, like books or toys. Liquids, like water and juice, can flow and take the shape of their container. Gases, like the air we breathe, are all around us even though we can't see them. So, matter includes everything from the tiniest grain of sand to the air we breathe!"
