Crash Course Chemistry #17-#31 Video Lesson Set | Thermochemistry, Bonding, Equilibrium & pH

Make advanced chemistry topics easier to teach with a no-prep 15-episode YouTube video lesson set focused on energy, enthalpy, calorimetry, entropy, lab safety, chemical bonding, polarity, Lewis structures, orbitals, liquids, solutions, equilibrium, pH, pOH, buffers, and acid rain chemistry.

This set helps students build a stronger chemistry foundation after atomic structure, stoichiometry, reactions, and gas laws. Students move into energy changes, molecular structure, bonding models, intermolecular forces, solution behavior, equilibrium thinking, acid-base math, and buffer systems. Each lesson gives students a structured way to follow the video, explain key ideas, use chemistry vocabulary, and show understanding through written responses or a multiple-choice quiz.

Use this video guide set for Grades 8-12 chemistry, physical science, NGSS review, science literacy, sub plans, flipped lessons, unit review, or flexible chemistry enrichment.
