What is Matter by: meagan Gray


Matter is anything that has mass and takes up space. Matter is all around you. You see it everyday. Some examples of matter are the student desk, the chair you sit in, your backpack, even liquids are matter. Even you are matter!

Now there are two types of matter there are pure substances and there is mixtures.

What is a Pure Substance

A pure substance is made up of one thing.

What is a Pure Substance

A pure substance is made up of one thing. A pure substance can either be an element or a compound. A element is one element. While a compound is made up of more than one type of element.

What you know as table salt is a element which is a pure substance.

The Other Kind of Matter

The other kind of matter that we are going to talk about is mixtures. A mixture is two or more compounds. Mixtures can be a lot of things.

Sand is a mixture. It contains more than one compound. Sand is just one mixture. There is sugar and flour and so many more.

Now it is time to talk about the two types of mixtures. The first mixture I want to talk about is the homogeneous mixture. Homogeneous mixtures are solutions. A solution is a homogeneous mixture of particles so small that they cannot be seen with a microscope and will NEVER settle to the bottom of there container. Homogeneous mixtures are uniform throughout. That means you can´t see the particles and as we said before that they will not settle to the bottom of their container. So lets look at some examples.

Oxygen the air we breath is a homogeneous mixture. It is a solution. While we are in everyday life we are seeing feeling and even breathing in homogeneous mixtures.

Salt water is also a homogeneous mixture and there are so many other others.

The next thing I want to talk about is heterogeneous mixtures. A heterogeneous mixture is a mixture in which different materials can be seen easily. Now lets look at an example of a heterogeneous mixture.

Water and oil is an example of a heterogeneous mixture. You can easily see the two particles in the mixture.

Lets talk about the types of heterogeneous mixtures. There are suspension and colloid. Suspension is a liquid in which visible particles settle. While a colloid is where the particles that are larger in solutions but not heavy enough to settle out.

Now lets give some examples of suspension.

Rocks and water is a suspension. They will always settle to the bottom of their container.

Milk is a colloid. The particles never settle to the bottom of the container.

Now you know a little about matter.
