Chemistry

About this course

This is a dedicated full-year chemistry course rather than a chemistry unit inside a general science book. It opens with the nature of matter, physical and chemical change, separation methods, SI units, and significant figures, then works through atomic structure and isotopes, electron configuration, the periodic table and its trends, ionic and covalent and metallic bonding, Lewis structures and molecular shape, and writing and balancing equations for the common reaction types. From there the course turns quantitative: the mole, molar mass, empirical and molecular formulas, mole-to-mole and mass-to-mass stoichiometry, limiting reactant, and percent yield. The second half covers kinetic molecular theory and the gas laws through the ideal gas equation and Dalton's law of partial pressures, solutions with molarity and dilution, acids and bases with pH, titration, and buffers, thermochemistry and Hess's law, reaction rates and rate laws and equilibrium with ICE tables, oxidation numbers and balancing redox by half-reactions along with galvanic and electrolytic cells, an introduction to organic chemistry through the common functional groups, and nuclear chemistry from decay types and half-life to fission, fusion, radiation safety, and medical isotopes.

There are 180 lessons in 15 units of 12, planned at about 55 minutes each, which fills a standard school year at one lesson a day. A lesson opens with prayer, moves into a reading built from short headed sections, bolded definitions, and two to four fully worked numerical examples with the units carried through, and asks your student to copy vocabulary and the worked examples into a science notebook by hand. Each lesson closes with a KJV verse tied to the day's chemistry and a ten-question multiple-choice quiz that grades itself. The listed materials are only a pencil, paper, a Bible, a science notebook, and a printed periodic table.

Three things are worth weighing before you assign it. First, the mathematics is real and constant: your student will rearrange formulas, work with ratios and proportions, use scientific notation and significant figures, and meet logarithms in the pH lessons, so Algebra I should be finished and comfortable rather than freshly learned. Second, there is no laboratory component. Some lessons describe procedures such as titrating from a burette or collecting a gas over water, but no experiment is assigned and no kit, glassware, or chemicals are supplied, so if a transcript or an outside program requires documented lab hours, you and your family will need to arrange them separately. Third, Freedom Homeschool also offers a general tenth-grade science course, which is integrated across life, earth, physical, and space science and carries a chemistry strand that overlaps this course's early and middle units; most families will assign one or the other as the year's science rather than both. On worldview, the nuclear unit teaches the young-earth position directly, laying out the assumptions behind radiometric dating and the RATE Project research as the course's own position rather than as one view among several.

One whole lesson, exactly as it comes

This is a real lesson taken from the middle of the course — the teaching text, the practice, the homework, and the first three quiz questions with their answers. It is not a marketing excerpt.

What you will need
