Standard: Physical Science

Students demonstrate an understanding of the composition of physical systems and the concepts and principles that describe and predict physical interactions and events in the natural world. This includes demonstrating an understanding of the structure and properties of matter, the properties of materials and objects, chemical reactions and the conservation of matter. In addition, it includes understanding the nature, transfer and conservation of energy; motion and the forces affecting motion; and the nature of waves and interactions of matter and energy. Students demonstrate an understanding of the historical perspectives, scientific approaches and emerging scientific issues associated with the physical sciences.

• Benchmark A: [6-8]
  Relates uses, properties and chemical processes to the behavior and/or arrangement of the small particles that compose matter.
  

• Benchmark B: [6-8]
  In simple cases, describe the motion of objects and conceptually describe the effects of forces on an object.
  

• Benchmark C: [6-8]
  Describe renewable and nonrenewable sources of energy(e.g., solar, wind, fossil fuels, biomass, hydroelectricity, geothermal and nuclear energy) and the management of these sources.
  

• Benchmark D: [6-8]
  Describe that energy takes many forms, some forms represent kinetic energy and some forms represent potential energy; and during energy transformations the total amount of energy remains constant.
