record and compare how the structures and behaviors of animals help them find and take in food, water, and air;
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
Patterns are regular sequences that can be found throughout nature.
Patterns of similar shape, size, or arrangement occur among different animal structures. There are also patterns in the behaviors of herbivores and carnivores.
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 animal system is composed of structures and behaviors used for the location of resources, movement, and resource intake. Each part has a role in the survival of the animal.
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. It is important to note that in kindergarten – grade 2, students focus on structures as an organized arrangement of parts within an organism or object.
The structures and behaviors of different animals are specialized to meet the needs of each animal (function).
Stability describes a system that does not change at the observed scale. In a stable system, a small disturbance will die out and the system will return to a stable state. Change in the system can come from modifying a factor or condition.
The animal system is composed of structures and behaviors used for movement, resource location, and resource consumption. A factor (change) that affects any of the structures or behaviors can affect the stability of the animal system, impacting its survival.
