Unit Learning Objectives
- Define chemistry broadly as the accumulated knowledge, skills, methods, and procedures, that people use to manipulate matter to serve human needs.
- Describe and outline a basic classification scheme for matter.
- Classify a sample of matter as either a pure substance (elements and compounds), or mixture (homo or heterogeneous).
- Distinguish between heterogeneous and homogeneous samples of matter.
- Distinguish between an element and a compound and know that compounds can be separated by chemical means such as electrolysis.
- Understand the basic process of distillation and how it is used to separate homogeneous mixtures (solutions) into their constituent parts. (recall the early alchemist Jabir used this method).
- Distinguish between the terms compound and molecule.
- Use appropriate examples to distinguish between physical and chemical change.
- Use appropriate examples to distinguish between physical and chemical properties.
- Develop models to describe atomic composition of simple (or complex) molecules and extended structures. In the model, students can identify the relevant components including, individual atoms, molecules, extended structures, and substances (e.g., solids liquids and gases at the macro level).
