EXPLORATION 1 Matter Is Everything What Matters about Matter Where do you find things made of matter? If you can taste, smell, or touch something, it’s matter. Anything that takes up space is matter. It can come in different forms and can behave in many different ways. Even a breeze is matter, because air takes up space. But some things that exist, such as heat and light, are not matter. Why not? They don’t take up any space. At the Fair 2. What do the sun, tents, and carnival games have in common? © Houghton Mifflin Harcourt 78  Matter or Not? Explore 3.

The term state refers to how the particles of the matter are behaving. Sometimes scientists call states of matter phases. A solid is the state of matter that has definite shape and volume. A solid’s particles are tightly packed together and only vibrate in place. A liquid has no definite shape but does have a definite volume. A liquid’s particles are not as tightly packed and can flow past each other. A gas has neither definite shape nor definite volume. Its particles have space between them to move freely. 12. Look at the images of matter in different states, and then write down your observations. Focus on shapes and volumes. Do they change? The shoe consists mainly of different solid materials.

Pack the paper towel into the bottom of the plastic cup. Hold the cup upside down, with paper towel packed inside, and push it straight down into the bowl all the way to the bottom. Hold it there for a minute, and then pull the cup out the same way it went in—upside down. What do you notice about the paper towel? Does that prove that air is matter? Putting It Together Matter is all around us. It can be broken down from a large size to a small size, but its identity doesn’t change. If you add more of the same matter to the original amount of matter, it is still the same substance. © Houghton Mifflin Harcourt 15.
