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.
1.2. Grade Level Indicator: Earth Systems: Explain that the supply of many resources is limited but the supply can be extended through careful use, decreased use, reusing and/or recycling.
1.D. Describe what resources are and recognize some are limited but can be extended through recycling or decreased use.
OH.4. Science and Technology: Students recognize that science and technology are interconnected and that using technology involves assessment of the benefits, risks and costs. Students should build scientific and technological knowledge, as well as the skill required to design and construct devices. In addition, they should develop the processes to solve problems and understand that problems may be solved in several ways.
4.3. Grade Level Indicator: Understanding Technology: Identify some materials that can be saved for community recycling projects (e.g., newspapers, glass and aluminum).
