Chemical Concepts

An Introductory Course

The learning outcomes of Introduction to Chemistry are for learners to be comfortable with the periodic table of the elements and also with using the notation of chemistry. In the first half of the course, we learn the basic theory of how tiny atoms, ionic compounds, and molecules fit together. In the second half of the course, we apply these concepts to understand what atoms do in a variety of chemical reactions. The course concludes by introducing “stoichiometry,” a fancy word for “ratios,” in which we use the periodic table to predict the outcome of an experiment. There is an hour-long experiment during the last class, in which we learn to write proper lab reports. Learners are encouraged to repeat the experiments with parental supervision by watching the class recording.

Assignments: The written assignment for each class requires about 1-2 hours out of class.

Prerequisite: Know arithmetic including addition, subtraction, multiplication and division.

lesson 1: Welcome, how to learn chemistry
lesson 2: The periodic table of the elements, subatomic particles, charge
lesson 3: Neutrons, isotopes, average mass

Immersive Chemistry First Semester

There are two learning outcomes for the First Semester Chemistry. In the first half of the course, learners will understand how molecular structure can impact the bulk matter that we can see and touch. Second, learners will become comfortable with ratio (stoichiometric) calculations that link the theory embedded the periodic table to the real world. The course covers topics traditionally presented in the first semester of chemistry at the high school, AP, and first-year college level. (These different levels essentially cover the same generalized topics, in very different levels of detail and rigor.) The course is geared towards chemistry that takes place in a “wet lab,” and there will be various laboratory demonstrations and experiments which the learners may perform at home with parental supervision.

Assignments: The written assignment for each class requires about 1-3 hours out of class.

Prerequisites: Be familiar with the periodic table to the extent of counting protons, neutrons, electrons, charge, and simple ionic bonding. Draw simple electron dot structures. Know how to write chemical reactions. Arithmetic skills and a calculator are required.

lesson 1: Binary ionic compounds, emission spectra, EM spectrum, colored light
lesson 2: Ionic bonding: polyatomic ions (the 5 “-ates”), acids, bases
lesson 3: Covalent bonding: electronegativity, Lewis structures
lesson 4: Covalent bonding: resonance, polarity
lesson 5: Covalent bonding: 3D molecule geometry (VSEPR) with Balloons Experiment
lesson 6: Solutions: dissolution, homogeneity, states of matter with Sand/Salt Separation Experiment
lesson 7: Solutions: Intermolecular forces (IMFs) with Mixing Liquids Experiment
lesson 8: Solutions: water, hydrogen bonding, boiling points, with Freezing Time for Water Experiment
lesson 9: Stoichiometry: balancing chemical reactions
lesson 10: Designing experiments, writing lab reports, Volume Change of Water/Ice Experiment
lesson 11: Stoichiometry: mole ratios, introduction to biochemistry, Soap IMFs Experiment
lesson 12: Stoichiometry: limiting reactants, ICE tables
lesson 13: Lab reports
lesson 14: Stoichiometry: molarity, acid/base reactions, pH, gas producing neutralizations
lesson 15: Stoichiometry: titration calculations with Neutralization & pH Indicator Experiments

Immersive Chemistry Second Semester

The learning outcome for Second Semester Chemistry is to understand how the theory of chemistry can be applied to understand a wide variety of real-world phenomenon, both in the laboratory as well as everyday life. The course covers “applied chemistry” topics traditionally presented in the second semester of chemistry at the high school, AP, and first-year college level. (These different levels essentially cover the same generalized topics, in very different levels of detail and rigor.) The course is geared towards practical aspects of chemistry. Learners will be able to provide conceptual explanations and simple calculations reflecting the chemistry that creates the world around them. There will be laboratory demonstrations, and longer laboratory experiments will be performed in an optional online lab group arranged separately.

Assignments: The written assignment for each class requires about 1-3 hours out of class.

Prerequisites: Be familiar with the periodic table and have some experience with stoichiometric calculations. Understand chemical bonding. Arithmetic skills and a calculator are required.

lesson 1: Thermodynamics: heat vs. temperature, heat equation
lesson 2: Thermodynamics: heat of reaction
lesson 3: Gasses: pressure, vapor pressure, absolute temperature
lesson 4: Equilibrium: Eq constant, Le Chatelier principle
lesson 5: Equilibrium: acid dissociation constants (Ka) with Titration Curves Experiment
lesson 6: Equilibrium: pH and pOH with pH Indicator Experiment
lesson 7: Equilibrium: buffer solutions, Henderson-Hasselbalch equation
lesson 8: Equilibrium: titration curves, half-equivalence point method
lesson 9: Kinetics: power laws for rates of reactions
lesson 10: Kinetics: Integrated Rate Laws
lesson 11: Kinetics: Method of Initial Rates
lesson 12: Kinetics: Reaction mechanisms, elementary steps
lesson 13: Electrochemistry: reduction-Oxidation (RedOx) reactions, oxidation states
