    Analyzing and Interpreting Data - Analyze and interpret data to determine similarities and differences in findings.

  • Disciplinary Core Ideas

    LS1.D: Information Processing - In complex animals, the brain is divided into several distinct regions and circuits, each of which primarily serves dedicated functions, such as visual perception, auditory perception, interpretation of perceptual information, guidance of motor movement, and decision making about actions to take in the event of certain inputs. In addition, some circuits give rise to emotions and memories that motivate organisms to seek rewards, avoid punishments, develop fears, or form attachments to members of their own species and, in some cases, to individuals of other species (e.g., mixed herds of mammals, mixed flocks of birds). The integrated functioning of all parts of the brain is important for successful interpretation of inputs and generation of behaviors in response to them.

    Patterns - Use patterns to identify cause and effect relationships, and use graphs and charts to identify patterns in data.
