Kentucky Standards

KY.CC. Core Content for Assessment v.4.1
SC-08-3.5. Biological Change: At the middle school level, students study relationships among populations and ecosystems that contribute to the success or demise of a specific population or species. Students construct basic explanations that can account for the great diversity among organisms.
SC-08-3.5.1. Biological Science: Students will draw conclusions and make inferences about the consequences of change over time that can account for the similarities among diverse species.
SC-08-4.7. Interdependence: In middle school, students should be guided from specific examples of the interdependency of organisms to a more systematic view of the interactions that take place among organisms and their surroundings.
SC-08-4.7.1. Unifying Concepts: Students will describe the interrelationships and interdependencies within an ecosystem and predict the effects of change on one or more components within an ecosystem.
KY.PS. Program of Studies 2006
SC-8-BC. Big Idea: Biological Change (Biological Science) - The only thing certain is that everything changes. At the middle school level, students study relationships among populations and ecosystems that contribute to the success or demise of a specific population or species. Students construct basic explanations that can account for the great diversity among organisms. (Academic Expectations 2.1, 2.2, 2.5, 2.6)
SC-8-BC-S-3. Program of Studies: Skills and Concepts - Students will research the most common fossils used to support theories of biological change
SC-8-I. Big Idea: Interdependence (Unifying Concepts) - It is not difficult for students to grasp the general notion that species depend on one another and on the environment for survival. But their awareness must be supported by knowledge of the kinds of relationships that exist among organisms, the kinds of physical conditions that organisms must cope with, the kinds of environments created by the interaction of organisms with one another and their physical surroundings, and the complexity of such systems. In middle school, students should be guided from specific examples of the interdependency of organisms to a more systematic view of the interactions that take place among organisms and their surroundings. Students growing understanding of systems in general will reinforce the concept of ecosystems. Stability and change in ecosystems can be considered in terms of variables such as population size, number and kinds of species, productivity, and the effect of human intervention. (Academic Expectations 2.1, 2.2, 2.3, 2.4)
SC-8-I-S-2. Program of Studies: Skills and Concepts - Students will analyze ecosystems to identify patterns of cooperation that enhance stability
SC-8-I-U-1. Program of Studies: Understandings - Students will understand that organisms both cooperate and compete in ecosystems. Balanced patterns of cooperation and competition may generate ecosystems that are relatively stable for hundreds or thousands of years.
