Attention Getting Question:
Do you wonder what we call everything around us?
Matter is anything that has mass and takes up space. Mass is the amount of matter in an object. Matter is all around you! Let’s learn more about it.
Everything in our world is made of matter. Matter is all of the objects we can see and feel. Some matter is even invisible, like air. Our five senses can help us describe matter. Big, small, soft, hard, hot, and cold are some properties, or characteristics, used to describe matter.
We can use tools to measure properties. For example, a balance is used to find the mass of objects. If we compare two objects on a balance, we can easily see which object has more mass. The heavier the object is, the more mass it has. We use grams to measure mass in matter. Balances are used for measuring mass, while scales are used for measuring weight, or how heavy something is.
All matter is made up of tiny particles that can’t be seen with the eye or a magnifying lens. The way these particles are arranged and move, determine the state of matter. There are three states of matter: solids, liquids, and gases.
Solids are made up of vibrating particles that are close together. A solid has its own shape and volume, or the amount of space matter takes up. Solids keep their shape unless a force changes them. A block, an apple, a shoe, and a teddy bear are types of solids.
A liquid, however, does not have a shape of its own, but it does have volume. The particles in liquids are not as tightly packed together as solids. They slide past each other and move about. This helps liquids take the shape of their container. Water, liquid soap, and syrup are types of liquids.
Gases, unlike solids and liquids, do not have a shape or volume of their own.They take the shape of their containers like liquids do, but they expand to fill whatever space is available. The particles in gases are farther apart and move about freely.Air and steam from a boiling pot are types of gas.
Did you know matter can change from one state to another? When water becomes an ice cube inside a freezer, it has changed from a liquid into a gas. If you take the ice cube out of the freezer and place it on a table, it will melt as its temperature changes. If you keep the water left from the melted ice cube on the table, it will eventually evaporate and change from a liquid to a gas.
Everything is made up of matter. All matter has mass and takes up space. Properties are words used to describe matter. There are three forms of matter: solids, liquids, and gases. Solids have volume and a shape of their own. Liquids have volume, but no shape of their own. Gases do not have shapes or volumes of their own. Can you name the different forms of matter around you?
