GED® Science: Matter and Its States (Deep Dive)

A deep dive into matter, expanding the single 'Matter and Its States' lesson from the GED® Physical Science course into a full mini-course. You'll use the particle model to understand solids, liquids, and gases, follow how matter changes state, read heating curves, calculate and compare density, tell physical changes from chemical changes, and learn about mixtures and solutions. Plain language, all-new labeled diagrams, common-misconception warnings, and GED®-style practice with full explanations throughout.
