DE.2. Materials and Their Properties
2.1. Properties and Structure of Materials
Enduring Understanding: The structures of materials determine their properties.
2.1.D. An important property of materials is their ability to conduct heat. Some materials, such as certain metals, are excellent conductors of heat while other materials, such as glass, are poor conductors (good thermal insulators). (Level: Important)
DE.3. Energy and Its Effects
3.1. The Forms and Sources of Energy
Enduring Understanding: Energy takes many forms. These forms can be grouped into types of energy that are associated with the motion of mass (kinetic energy), and types of energy associated with the position of mass and with energy fields (potential energy).
3.1.D. Heat energy comes from the random motion of the particles in an object or substance. Temperature is a measure of the motion of the particles. The higher the temperature of the material, the greater the motion of the particles. (Level: Important)
3.2. Forces and the Transfer of Energy
Enduring Understanding: Changes take place because of the transfer of energy. Energy is transferred to matter through the action of forces. Different forces are responsible for the transfer of the different forms of energy.
3.2.F. The addition or removal of heat energy from a material changes its temperature or its physical state. (Level: Important)
3.2.G. Heat energy is transported by conduction, convection, and radiation. Heat energy transfers from warmer substances to cooler substances until they reach the same temperature. (Level: Essential)
