Matter - Properties and Change

In lesson 1, we talk about matter as being anything that has mass and takes up space. Matter makes up the world around us and can exist in and change between different states. We will also look at how we can measure the mass and volume of different objects and substances.

The property of density measures the amount of matter in a fixed volume. An objects density shows the relationship between the mass and volume of an object or substance. Density is measured in grams per cubic centimeter. In a very dense material, the molecules will be packed tightly together; but in a less dense material, there will be more space between molecules. 

In lesson 3, we will begin to explore several properties of matter. All matter has properties – characteristics that allow it to be described and classified. In this lesson, we will begin our study of properties of matter by looking at physical properties. Physical properties are the characteristics that can be observed and measured without chemically changing the object or substance. Physical properties include characteristics like color, density, melting point, and more.
