DE.4. Earth in Space
4.1. The Earth/Moon/Sun System
Enduring Understanding: There are observable, predictable patterns of movement in the Sun, Earth, and Moon system that account for day/night.
4.1.C. The Sun and Moon appear to move slowly across the sky. (Level: Important)
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. Components of Earth's system include minerals, rocks, soil, water and air. These materials can be observed, sorted and/or classified based on their physical properties. (Level: Essential)
5.1.B. Water can exist as a solid, liquid or gas and in different forms such as rain, snow and ice. (Level: Important)
5.1.C. Sand, clay and humus have distinct physical properties and are components of soils. (Level: Essential)
5.1.F. Rocks are natural combinations of minerals. Minerals can be classified according to their physical properties (i.e., luster, color and hardness). (Level: Essential)
5.3. Technology and Applications
Enduring Understanding: Technology enables us to better understand Earth's systems. It also allows us to analyze the impact of human activities on Earth's systems and the impact of Earth's systems on human activity.
5.3.B. Weather can be observed, measured and described through the use of simple tools such as a thermometer, rain gauge and wind vane. (Level: Important)
