Course Summary

Throughout this course, students will investigate the fundamental building blocks of matter and develop an understanding of how substances are organized and transformed. Beginning with the particle model and atomic structure, students will explore the nature of atoms, elements, and isotopes before examining how the periodic table organizes the known elements. Students will then learn how atoms combine to form compounds through ionic and covalent bonding and how chemical formulae are used to represent substances.

The course continues with the study of mixtures and solutions, where students learn how substances can be physically separated using techniques such as filtration, evaporation, distillation, and chromatography. Finally, students investigate chemical reactions, identifying evidence of chemical change, interpreting reactants and products, applying the law of conservation of mass, and writing and balancing chemical equations.

By the end of the course, students will understand how matter is structured at the atomic level, how elements combine to form compounds, how mixtures can be separated, and how chemical reactions transform substances while conserving mass. These concepts provide the essential foundation for future studies in stoichiometry, energetics, electrochemistry, organic chemistry, and many other areas of chemistry.
