This session is part one in a series of four on the New Science TEKS for sixth through eighth grade. In Matter and Energy, participants will begin to understand the new science and engineering practices (SEPs) and updates to the 6-8 content strands. SEP topics will include science and engineering, engineering design process, claim-evidence-reasoning, introduction to recurring themes and concepts, and design problems. Science content topics will include chemical symbols, chemical formulas, the periodic table, mixtures and solutions, water transport in plants, acids and bases (pH), phases of matter, and relative density.
