Arizona's College and Career Ready Standards
Core Ideas for Knowing Science
L2: Organisms require a supply of energy and materials for which they often depend on, or compete with, other organisms.
First Grade: Focus on Cause and Effect; Stability and Change (cycles)
Life Sciences: Students develop an understanding that the Earth has supported, and continues to support, a large variety of organisms. These organisms can be distinguished by their physical characteristics, life cycles, and their different resource needs for survival. Different types of organisms live where there are different earth resources such as food, air, and water.
