Chemistry Videos for High School: Summary

Our fun chemistry videos for high school are organized into a series of 3 courses with progressively more challenging chemistry topics. Each course is about half a school year (a semester) in duration.

The first Self Paced course is called Introduction to Chemistry. These fun chemistry videos start at the beginning. They cover everything you really need to know for success with high school chemistry topics.

The next set of videos is called First Semester Chemistry. It continues from the previous video course into the core high school chemistry topics. The course will also prepare learners for that critical first semester of college level science classes, which is what the “First Semester” in the course name refers to.

The next set of chemistry videos is called Second Semester Chemistry. It continues into the advanced high school chemistry topics and experiments that would often be covered in an honors chemistry class or an AP chemistry class. Most students won’t encounter these topics until the second semester of college, and it’s not necessary to complete this course to get high school credit for chemistry.

The courses are formatted as semester length (half year) courses, and we suggest taking 2 of the 3 chemistry courses to complete a “normal” school year. Beginners can take Introduction and First Semester for a complete year of chem, while advanced learners can take First Semester and Second Semester to complete a year. There’s more specific info about the topics covered below.

Your Online Chemistry Teacher

online homeschool high school chemistry course instructor headshot

Hi, I’m Dr. Scott, the course instructor for Introduction to Chemistry, First Semester Chemistry, and Second Semester Chemistry.

I’m a former college chemistry professor that knows how to make learning science fun and easy. I spent waaaaay too many years watching students fail “hard” college science courses because they didn’t get the fundamentals.

My courses will show you how to learn science, and I guarantee they’ll prepare you for future science classes. The easy way.

Chemistry Videos: Second Semester Chemistry

Each lesson of Second Semester Chemistry has an experiment demonstrating the chemistry principles covered in that lesson. These are advanced lessons that most learners won’t encounter until college. Topics are listed below.

Chemistry Videos Topics: Introduction to Chemistry Course

Lesson 1: Getting Started

Learn about how brain science (neuroscience) relates to learning chemistry for homeschoolers. Learn to learn the easy way!

Lesson 2: Periodic Table, Subatomic Particles, Charge

A core lesson about “reading” the periodic table to understand atoms, elements, subatomic particles, protons, electrons, valence electrons, neutrons, charge, atomic number, mass, atomic structure, metals, transition metals, and periodic trends. We’ll learn about the differences between pure, neutral elements and their impure, non-neutral forms, known as ions. 

Lesson 3: Isotopes, Average Mass

We’ll explore the neutron further, leading to the understanding of isotopes. We will learn about the concept of averages in science, and specifically average mass (the mass number, or atomic mass) on the periodic table.

Lesson 4: Aufbau Diagrams, Ionic Compounds

We will learn about electron configurations, Aufbau diagrams, electron spin, the Pauli exclusion principle, Hund’s Rule, quantum numbers, the octet rule for ions, and simple binary ionic compounds, commonly known as the salts and minerals found on Earth.

Lesson 5: Electron Dot Diagrams, Molecules

We will learn to draw molecules (it’s fun), using dot diagrams and Lewis structures. We will learn about the octet rule for neutral nonmetal atoms, sigma bonds, pi bonds, single bonds, double bonds, and triple bonds.

Lesson 6: Polarity, 3D Shapes with Balloons Lab Demo

We will learn about polarity for neutral molecules. There is a hands-on experiment to observe the 3D shapes of molecules (VSEPR theory). This optional activity is Dr. Scott’s personal favorite experiment.

Lesson 7: Acid-Base Neutralization

We will learn about acids, bases, and the reactions between them, known as a neutralization reaction. We will learn about Arrhenius acids, Arrhenius bases, organic acids, and monoprotic acids, diprotic acids, and triprotic acids.

Lesson 8: Precipitation, States of Matter

Will will learn about the states of matter (solid, liquid, gas, and also aqueous solutions). We will discuss solubility, dissolution, and precipitation reactions, in which a solid appears out of a solution. There’s a lab demo video with a dramatic reaction… and a decent joke too.

Lesson 9: Reduction-Oxidation (RedOx)

We will learn about redox reactions for the transition metals, reduction half reactions, oxidation half reactions, reducing agents, oxidizing agents, and electron transfer. We will learn how redox relates to biochemistry, electrochemistry, and metals reacting with acid.

Lesson 10: Mole Ratios

We will learn about moles (mol), the fundamental unit for chemicals. The idea will extent to mole ratios for which chemicals react, formally known as stoichiometry.

Lesson 11: Molar Mass, Rounding

We will learn about molar mass, also known as molecular weight. This key concepts allows us to measure chemicals in a lab to perform experiments with correct mole ratios. We will learn to apply precision and rounding to measurements and stoichiometric ratios.

Lesson 12: Limiting Reactants Experiment

We will put it all together for a scientific experiment featuring an acid base reaction that generates gas. There’s a big emphasis on the safety of experiments from the perspective of professional scientists, so that learners are prepared for future lab work. Learners will make a report and optionally repeat the experiment at home as the final course project.

Chemistry Videos Topics: First Semester Chemistry Course

Lesson 1: Binary Ionic Compounds, Emission Spectra

We’ll learn about ions and binary ionic compounds, using the octet rule. We will learn about EM waves and line emission spectra for elements.

Lesson 2: Absorbance, Polyatomic Ions

We’ll learn about polyatomic ions and general ionic compounds We will learn about absorbance for EM waves.

Lesson 3: Electronegativity, Lewis Structures

We will learn the theory behind covalent bonding and it’s connection to Pauling electronegativity. It’s probably the most important concept in all of chemistry!

Lesson 4: Polarity, Resonance
