OH.1. Earth and Space Sciences: Students demonstrate an understanding about how Earth systems and processes interact in the geosphere resulting in the habitability of Earth. This includes demonstrating an understanding of the composition of the universe, the solar system and Earth. In addition, it includes understanding the properties and the interconnected nature of Earth's systems, processes that shape Earth and Earth's history. Students also demonstrate an understanding of how the concepts and principles of energy, matter, motion and forces explain Earth systems, the solar system and the universe. Finally, they grasp an understanding of the historical perspectives, scientific approaches and emerging scientific issues associated with Earth and space sciences.
1.1. Grade Level Indicator: Earth Systems: Compare distinct properties of rocks (e.g., color, layering and texture).
1.3. Grade Level Indicator: Earth Systems: Describe that smaller rocks come from the breakdown of larger rocks through the actions of plants and weather.
1.4. Grade Level Indicator: Earth Systems: Observe and describe the composition of soil (e.g., small pieces of rock and decomposed pieces of plants and animals, and products of plants and animals).
1.5. Grade Level Indicator: Earth Systems: Investigate the properties of soil (e.g., color, texture, capacity to retain water, ability to support plant growth).
1.B. Summarize the processes that shape Earth's surface and describe evidence of those processes.
1.D. Analyze weather and changes that occur over a period of time.
