DE.3. Energy and Its Effects
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.D. When energy from the sun is transferred to objects and substances, it can be transformed into a variety of energy forms. (Level: Essential)
DE.4. Earth in Space
4.1. The Earth/Moon/Sun System
Enduring Understanding: Observable, predictable patterns of movement in the Sun, Earth, Moon system occur because of gravitational interaction and energy from the Sun.
4.1.A. The Sun is a star that gives off radiant energy that drives Earth systems and is essential for life. The amount of radiant energy Earth receives from the Sun throughout the year is nearly constant. (Level: Essential)
DE.5. Earth's Dynamic Systems
5.1. Components of Earth
Enduring Understanding: Earth's systems can be broken down into individual components which have observable measurable properties.
5.1.A. Water exists on the Earth in reservoirs (on or within the Earth's surface and atmosphere). The total amount of water in these reservoirs does not change, however, the ratio of water in solid, liquid, or gaseous form varies over time and location. (Level: Essential)
5.1.B. The movement of water among the geosphere, hydrosphere and atmosphere affects such things as weather systems, ocean currents, and global climate. (Level: Essential)
5.2. Interactions Throughout Earth's Systems
Enduring Understanding: Earth's components form systems. These systems continually interact at different rates of time, affecting the Earth locally and globally.
5.2.A. Water cycles from one reservoir to another through the processes of evaporation, transpiration, condensation and precipitation. Energy transfers and/or transformations are associated with each of these processes. (Level: Essential)
8.2. Energy Flow and Material Cycles in the Environment
Enduring Understandings: Matter needed to sustain life is continually recycled among and between organisms and the environment. Energy from the Sun flows irreversibly through ecosystems and is conserved as organisms use and transform it.
8.2.B. Over time, matter is transferred repeatedly from one organism to another and between organisms and their physical environment. As in all material systems, the total amount of matter remains constant, even though its form and location change. (Level: Essential)
