A student expectation is directly related to the knowledge and skills statement, is more specific about how students demonstrate their learning, and always begins with a verb. Student expectations are further broken down into their component parts, often referred to as “breakouts.”
Vertical alignment shows student expectations in the same subject area at different grade levels that are related to or build upon one another.
identify the different structures that animals have that allow them to interact with their environment such as seeing, hearing, moving, and grasping objects;
identify the external structures of different animals and compare how those structures help different animals live, move, and meet basic needs for survival;
record and compare how the structures and behaviors of animals help them find and take in food, water, and air;
explore and explain how external structures and functions of animals such as the neck of a giraffe or webbed feet on a duck enable them to survive in their environment; and
A system is a whole made of parts that work together. It has components and boundaries. It can interact with or be part of other systems.
The different organs (parts) of each body system work together to accomplish the functions of that system.
A structure is an organized arrangement of particles, parts, or elements in a substance, body, or entity. A function is the purpose or reason for something to exist in a system. The function of a structure depends on the shapes of and relationships among its essential parts.
Each organ or tissue has a unique structure that enables it to perform its function; for example, the skeletal system comprises cartilage, ligaments, and rigid bones that support and protect the body.
