OH.3. Physical Sciences: 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.
3.2. Grade Level Indicator: Nature of Energy: Describe how an object can have potential energy due to its position or chemical composition and can have kinetic energy due to its motion.
3.3. Grade Level Indicator: Nature of Energy: Identify different forms of energy (e.g., electrical, mechanical, chemical, thermal, nuclear, radiant and acoustic).
3.4. Grade Level Indicator: Nature of Energy: Explain how energy can change forms but the total amount of energy remains constant.
3.5. Grade Level Indicator: Nature of Energy: Trace energy transformation in a simple closed system (e.g., a flashlight).
3.C. 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.
3.D. 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.
OH.5. Scientific Inquiry: Students develop scientific habits of mind as they use the processes of scientific inquiry to ask valid questions and to gather and analyze information. They understand how to develop hypotheses and make predictions. They are able to reflect on scientific practices as they develop plans of action to create and evaluate a variety of conclusions. Students are also able to demonstrate the ability to communicate their findings to others.
5.B. Analyze and interpret data from scientific investigations using appropriate mathematical skills in order to draw valid conclusions.
