Acellus General Chemistry provides students with an introduction to the fundamentals of chemistry. Students build data analysis, critical thinking, and science communication skills while exploring various forms of matter, the composition of the atom, and organization of the periodic table. They will learn about properties of matter and use patterns to predict the behavior of atoms undergoing chemical reactions. They will understand chemical bonding and other interactions between atoms and molecules. They will explore the laws of conservation of mass and energy through calculations, including stoichiometry and calorimetry. Acellus Chemistry is taught by Nicole Lyssy. Students should take this course concurrently with, or after taking, Algebra II or Integrated Math III.

Scope and SequenceUnit 1: Chemistry Is a Laboratory Science This unit discusses basic laboratory principles including various scientific models, lab equipment, lab safety, and the fundamentals of designing a scientific experiment. Students will also learn how to properly collect, analyze, measure, and report data. Unit 2: Math for Chemistry In this unit, students will learn important fundamental mathematics concepts such as SI units, derived units, scientific notation, metric prefixes, dimensional analysis, unit conversion, and significant figures. Unit 3: Matter and Change This unit investigates matter -- how to identify it, its physical and chemical properties, and various states. Physical and chemical changes on microscopic, macroscopic, and representative forms are explored. Students will learn about safety data sheets commonly used in scientific laboratories. They will be introduced to common separation techniques. This unit also takes a first look at the periodic table, the implications of the law of conservation of mass, identifying types of mixtures, and calculating the percent by mass of a given compound. Unit 4: The Building Blocks of the Universe This unit explores the early atom and electron models, along with the discovery of alpha, beta, and gamma radioactive particles. This unit also covers isotopes, and atomic and molar mass. Students will also learn about nuclear stability and decay, fission and fusion, and how to define each type of radiation in terms of mass, charge, penetrating and ionizing power. Unit 5: What's in an Atom? This unit delves into radiation in our world, the photoelectric effect, spectra, the Bohr model, and the quantum mechanical model of the atom. Students will also perform calculations involving electromagnetic radiation, Planck’s constant, energy, and the speed of light. The latter part of this unit primarily focuses on fundamentals of quantum mechanics including electron shells, subshells, orbitals, the Aufbau Principle, Hund’s Rule, the Pauli Exclusion Principle, electron configuration, valence electrons, and Lewis dot structures.
