6.1 - Materials can be classified as pure substances or mixtures, depending on their chemical and physical properties.
a. Mixtures are made of combinations of elements and/or compounds, and they can be separated by using a variety of physical means.
b. Pure substances can be either elements or compounds, and they cannot be broken down by physical means.

C 1. Describe the properties of common elements, such as oxygen, hydrogen, carbon, iron and aluminum.
C 2. Describe how the properties of simple compounds, such as water and table salt, are different from the properties of the elements of which they are made.
C 3. Explain how mixtures can be separated by using the properties of the substances from which they are made, such as particle size, density, solubility and boiling point.
C 7. Describe the effect of heating on the movement of molecules in solids, liquids, and gases.
