Reporting Physical Science Category Standard Matter & Energy Transformations Benchmark SC.912.L.18.12 Number Benchmark Discuss the special properties of water that contribute to Earth's suitability as an environment for life: cohesive behavior, ability to moderate temperature, expansion upon freezing, and versatility as a solvent. Also None Specified Assesses Item Types Multiple Choice; Short Answer Cognitive Moderate Complexity Level Students will identify that water is a unique molecule and necessary for Benchmark life because of its specific and unique properties. Clarification Students will relate how the cohesive behavior of water gives it unique and special properties that contribute to its usefulness in plant life and animal life. Students will relate how the density change in freezing is essential to life on this planet. Students will explain how water is able to dissolve many substances making it an essential molecule for life. Students will understand the polar nature of a water molecule and how it relates to its special properties. Content Items will not assess hydrogen bonding, the freezing point of water, or other specific conceptual or numerical values of water. Limits Stimulus Illustrations or diagrams may be used. Attributes Response None Specified Attributes Content Focus atom, molecule, hydrogen bonds, covalent bonds, cohesion, adhesion, surface tension, capillary action, polarity, density, solvent, climate change, thermocline, pycnocline, latent heat, evaporation, condensation, melting, freezing, sublimation, heat capacity, climate, absorption, salinity, salt, parts per thousand, parts per million, buoyancy
