K-7 Standard P.EN: Develop an understanding that there are many forms of energy (such as heat, light, sound, and electrical) and that energy is transferable by convection, conduction, or radiation. Understand energy can be in motion, called kinetic; or it can be stored, called potential. Develop an understanding that as temperature increases, more energy is added to a system. Understand nuclear reactions in the sun produce light and heat for the Earth. P.EN.M.1 Kinetic and Potential Energy- Objects and substances in motion have kinetic energy. Objects and substances may have potential energy due to their relative positions in a system. Gravitational, elastic, and chemical energy are all forms of potential energy. Expectations   Vocabulary   Test Prep P.EN.06.11 Identify kinetic or potential energy in everyday situations (for example: stretched rubber band, objects in motion, ball on a hill, food energy).   Observe Evaluate Energy Force Motion Potential Energy Kinetic energy   P.EN.06.12 Demonstrate the transformation between potential and kinetic energy in simple mechanical systems (for example: roller coasters, pendulums).   Evaluate Energy Force Motion Communicating Potential Energy Pendulum Kinetic energy   P.EN.M.4 Energy Transfer- Energy is transferred from a source to a receiver by radiation, conduction, and convection. When energy is transferred from a source to a receiver, the quantity of energy before the transfer is equal to the quantity of energy after the transfer. Expectations   Vocabulary   Test Prep P.EN.06.41 Explain how different forms of energy can be transferred from one place to another by radiation, conduction, or convection.   Energy Conduction Heat Convection   P.EN.06.42 Illustrate how energy can be transferred while no energy is lost or gained in the transfer.   Energy Conduction Heat

	K-7 Standard P.CM: Develop an understanding of changes in the state of matter in terms of heating and cooling, and in terms of arrangement and relative motion of atoms and molecules. Understand the differences between physical and chemical changes. Develop an understanding of the conservation of mass. Develop an understanding of products and reactants in a chemical change. P.CM.E.1Changes in State- Matter changing from state to state can be explained by using models which show that matter is composed of tiny particles in motion. When changes of state occur, the atoms and/or molecules are not changed in structure. When the changes in state occur, mass is conserved because matter is not created or destroyed. Expectations   Vocabulary   Test Prep P.CM.06.11 Describe and illustrate changes in state, in terms of the arrangement and relative motion of the atoms or molecules.   Solid Liquid Gas Physical properties Motion States (phases)   P.CM.06.12 Explain how mass is conserved as it changes from state to state in a closed system.   Solid Liquid Gas Mass Physical properties States (phases)
