During this unit, we will be studying what matter is, how it is classified by scientists, and how properties are used to identify different substances.
Develop models to describe the atomic composition of simple molecules and extended structures.
Analyze and interpret data on the properties of substances before and after substances interact to determine if a chemical reaction has occurred.
Develop a model that predicts and describes changes in particle motioin, temperature, and state of a pure substance when thermal energy is added or removed.
classify examples of matter and non-matter
differentiate between atoms, molecules, elements, compounds and mixtures
classify the properties of matter as physical or chemical
differentiate between the properties of solids, liquids and gases
investigate the relationship among mass, volume and density
recognize that the elements are arranged in a periodic table according to their properties
