The second in a series of 11 note packs that cover a complete middle level, physical science course (chemistry and physics). Unit 2, "The Properties of Matter" includes the following content: Properties of Matter; Mass; Volume; Metric Measurement (units and Tools); Density of Matter and more (9 pages). The cover sheet includes a bullet list of student learning objectives. Information on each (one sided) note page is concise and accurate; topics are distilled for beginners but never "dumbed down" and the most important ideas, laws, theories, and scientific principles always receive the emphasis that they deserve. The complete set of 11 units is comprised of about 70+ pages and forms a complete physical science textbook that students find manageable and uncluttered.
