I created this as a study guide for an 8th grade physical science class. It is a follow up to my first study guide over this topic. It provides a review of: Atoms and Molecules, Measuring Matter, Physical and Chemical properties, Physical and Chemical changes, States of Matter, Changing states of matter, and Types of Matter (Pure substances, mixtures, and compounds). It provides a review of the material and also provides students with an array of quick assessment questions to check for understanding as they study. Questions include fill in the blank and matching.
