12.4.4 By the end of twelfth grade, students will develop an understanding of the interdependence of organisms.
- Investigate and understand that atoms and molecules cycle among living and nonliving components of the biosphere.
- Investigate and describe the flow of energy through ecosystems, in one direction, from producers to herbivores to carnivores and decomposers.
- Investigate and cite examples of organisms cooperating and competing in ecosystems.
- Investigate and understand that interactions among organisms are affected by the conflict between an organism's capacity to produce infinite populations and the finite amount of resources.
- Investigate and describe how humans modify the ecosystem as a result of population growth, technology, and consumption.
12.1.2 By the end of twelfth grade, students will develop an understanding of evidence, models, and explanation.
- Create a physical, mental, or mathematical model to show how objects and processes are connected.
- Test the usefulness of a model by comparing its predictions to actual observations.
- Understand that the way data are displayed affects interpretation.
- Evaluate the reasonableness of answers to problems.
- Understand that larger well-chosen samples produce more accurate estimates of the characteristics of the total population.
- Understand that a correlation between two variables doesn't mean that either one causes the other.
12.2.1 By the end of twelfth grade, students will develop the abilities needed to do scientific inquiry.
- Formulate questions and identify concepts that guide scientific investigations.
- Design and conduct scientific investigations.
- Use technology and mathematics to improve investigations and communications.
- Formulate and revise scientific explanations and models using logic and evidence.
- Recognize and analyze alternative explanations and models.
