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

Expected Performances (Outcomes) CMT Expectations C1. Describe the properties of common elements, such as oxygen, hydrogen, carbon, iron and aluminum.

C2. 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.

C3. 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.
