GPB Chemistry & Physics is a free high‑school video series from Georgia Public Broadcasting that walks through core concepts with demonstrations, animations, and on‑screen practice questions. Episodes are organized like a course and aligned to state standards, so families can use them as a spine alongside a textbook or problem set. Parents like that the host explains lab setups and safety while modeling how to think through problems, which is helpful if they don’t feel confident teaching upper‑level science themselves. Because it’s a broadcast‑style series, interaction is limited; students still need separate practice and labs. As a no‑cost resource, though, it dramatically lowers the barrier to offering full‑credit chemistry and physics at home.
