  1. Warm up and summarizing questions will be graded weekly- please write full question and answer for each day. If you miss a day please see a peer or myself after class to make up. October 19-23 Warm Ups & Summarizers Physical Science

  2. Monday October 19, 2015SPS5. Students will compare and contrast the phases of matter as they relate to atomic and molecular motion.SPS7. Students will relate transformations and flow of energy within a system. EQ: How does molecular motion compare with solids, liquids, and gases?
