Colorado Model Content Standards: Physical Geology Level 9
Standard 1 – Physical Science
Students apply the processes of scientific investigation and design, conduct, communicate about, and evaluate such investigations.
3. identify major sources of error or uncertainty within an investigation (for example: particular measuring devices and experimental procedures)
4. recognize and analyze alternative explanations and models
6. communicate and evaluate scientific thinking that leads to particular conclusions ES
Standard 2 – Physical Science
Students know and understand common properties, forms, and changes in matter and energy. (Focus: Physics and Chemistry)
Structure and Properties of Matter
1. elements can be organized by their physical and chemical properties (Periodic Table) ES
3. there are observable and measurable physical and chemical properties that allow you to compare, contrast, and separate substances (for example: pH, melting point, conductivity, magnetic attraction)
Forms and Transfer of Energy
7. light and sound waves have distinct properties; frequency, wavelengths and amplitude ES
Forces and Motion
Standard 3 – Life Science
Students know and understand the characteristics and structure of living things, the processes of life, and how living things interact with each other and their environment. (Focus: Biology-- Anatomy, Physiology, Botany, Zoology, Ecology)
Matter and Energy and Organization in Living Systems
1. the pattern/process of reproduction and development is specific to different organisms
2. there is a relationship between the processes of photosynthesis and cellular respiration (for example: in terms of energy and products)
3. there is a purpose of synthesis and breakdown of macromolecules in an organism (for example: carbohydrates, lipids, amino acids serve as building blocks of proteins; carbon dioxide and water are the basic materials for building sugars through photosynthesis)
4. energy is used in the maintenance, repair, growth, and production of tissues
5. the human body functions in terms of interacting organ systems composed of specialized structures that maintain or restore health (for example: mechanisms involved in homeostasis [balance], such as feedback in the endocrine system)
Populations and Ecosystems
6. changes in an ecosystem can affect biodiversity and biodiversity contributes to an ecosystem's dynamic equilibrium
7. there is a cycling of matter (for example: carbon, nitrogen) and the movement and change of energy through the ecosystem (for example: some energy dissipates as heat as it is transferred through a food web)
8. certain properties of water sustain life (for example: polarity, cohesion, solubility)
The Cell
9. cellular organelles have specific functions (for example: the relationship of ribosomes to protein, and the relationship of mitochondria to energy transformation)
10. cell reproduction/division has various processes and purposes (mitosis, meiosis, binary fission)
Basis of Heredity
11. DNA has a general structure and function and a role in heredity and protein synthesis (for example: replication of DNA and the role of RNA in protein synthesis)
12. genes serve as the vehicle for genetic continuity and the source of genetic diversity upon which natural selection can act
13. some traits can be inherited while others are due to the interaction of genes and the environment (for example: skin cancer triggered by over- exposure to sunlight or contact with chemical carcinogens)
Biological Evolution
14. organisms are classified into a hierarchy of groups and subgroups based on similarities which reflect their evolutionary relationships
15. mutation, natural selection, and reproductive isolation can lead to new species and affect biodiversity
16. an organism’s adaptations (for example, structure, behavior) determine its niche (role) in the environment
17. variation within a population improves the chances that the species will survive under new environmental conditions
18. organisms change over time in terms of biological evolution and genetics
Standard 4 – Earth and Space Science
Students know and understand the processes and interactions of Earth’s systems and the structure and dynamics of Earth and other objects in space. (Focus: Geology, Meteorology, Astronomy, Oceanography)
Earth’s Composition, Processes and History
1. the Earth’s interior has a composition and structure ES
4. there are costs, benefits, and consequences of natural resource exploration, development, and consumption (for example: geosphere, biosphere, hydrosphere, atmosphere and greenhouse gas)
5. there are consequences for the use of renewable and nonrenewable resources ES
Atmosphere and Weather
10. there are interrelationships between the circulation of oceans and weather and climate ES
Earth’s Water
12. water and other Earth systems interact (for example: the biosphere, lithosphere, and atmosphere)
13. continental water resources are replenished and purified through the hydrologic cycle ES
Solar System and the Universe
14. gravity governs the motions observed in the solar system and beyond
16. stars differ from each other in mass, color, temperature and age
17. the scales of size and separation of components of the solar system are complex
Standard 5
Students understand that the nature of science involves a particular way of building knowledge and making meaning of the natural world.
1. print and visual media can be evaluated for scientific evidence, bias, or opinion
2. the scientific way of knowing uses a critique and consensus process (for example: peer review, openness to criticism, logical arguments, skepticism)
3. graphs, equations or other models are used to analyze systems involving change and constancy (for example: comparing the geologic time scale to shorter time frame, exponential growth, a mathematical expression for gas behavior; constructing a closed ecosystem such as an aquarium) ES
5. scientific knowledge changes and accumulates over time; usually the changes that take place are small modifications of prior knowledge but major shifts in the scientific view of how the world works do occur
7. there is a difference between a scientific theory and a scientific hypothesis ES
