Humans

Humans are a species of highly intelligent primates known scientifically as Homo sapiens. They are the only extant members of the subtribe Hominina and are characterized by their bipedal locomotion, complex brain structure, and advanced social structures.

Physical Characteristics

Humans typically have a upright posture, opposable thumbs, and a highly developed brain capable of complex thought and reasoning. They have a wide range of skin colors, hair textures, and facial features, reflecting the diversity of human populations around the world.

Internal Systems

The human body is composed of various systems including the skeletal, muscular, circulatory, respiratory, digestive, nervous, and reproductive systems. Each system performs specific functions necessary for the overall health and survival of the individual.

Behavior and Culture

Humans are known for their complex social structures, communication through language, and the development of diverse cultures, traditions, and belief systems. They have the ability to create and use tools, and have a significant impact on their environment.

PHYSICAL SCIENCE

Motion and Stability: Forces and Interactions

Students who demonstrate understanding can:

Plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object.

Make observations and/or measurements of an object’s motion to provide evidence that a pattern can be used to predict future motion.

LIFE SCIENCE

From Molecules to Organisms: Structures and Processes

Students who demonstrate understanding can:

Develop models to describe that organisms have unique and diverse life cycles but all have in common birth, growth, reproduction, and death.

Biological Evolution: Unity and Diversity

Students who demonstrate understanding can:

Use evidence to construct an explanation for how the variations in characteristics among individuals of the same species may provide advantages in surviving, finding mates, and reproducing.

Construct an argument with evidence that in a particular habitat some organisms can survive well, some survive less well, and some cannot survive at all.

EARTH AND SPACE SCIENCE

Earth’s Systems

Students who demonstrate understanding can:

Represent data in tables and graphical displays to describe typical weather conditions expected during a particular season.

Obtain and combine information to describe climates in different regions of the world.
