This is the first part of a two part introductory course for students with limited or no background in chemistry; in this part of the course, chemical reactions, stoichiometry, nomenclature, and chemical problem solving will be emphasized. The goal of the course sequence is to prepare students for further study in chemistry as needed for many science, health, and policy professions. Topics include introductions to atoms, molecules, ions, the periodic table, stoichiometry, and chemical reactions.
Each week the course will contain a series of short video lectures with interactive questions embedded in the lectures. Students will have opportunities to practice each week via exercises at two levels of depth: one set of foundational problems directly related to lecture videos and another set of problems requiring more synthesis of ideas and application of pre-existing algebra skills. Students who complete the course while earning an average of 70% or more on the foundational problem sets and exam will receive a signed statement of accomplishment. Students who complete the course, participate fully in the peer-reviewed writing assignment, and achieve an average of 85% or more on the foundational problem sets, advanced problem sets, and exam will receive a signed statement of accomplishment with distinction.

Week One: Introductions with an overview of scientific methods, scientific notation, measurements, units and unit conversions, using proper significant figures to indicate precision, general concepts in matter and energy including definitions of atoms, elements, molecules, compounds, and moles, chemical formula stoichiometry, basic layout of the periodic table, examples of endothermic and exothermic reactions, and Coulomb’s law.
This is an introductory course for students with limited background in chemistry; basic concepts involved in chemical compositions, periodic trends, reactions, and quantitative problem solving will be emphasized with the goal of preparing students for further study in chemistry.
