life science |
 |
| |
Knows the general structure and functions of cells in organisms.
|
|
| |
Benchmark 6-8:
Knows that all organisms are composed of cells, which are the fundamental units of life; most organisms are single cells, but other organisms (including humans) are multicellular.
Benchmark 6-8:
Knows that multicellular organisms have a variety of specialized cells, tissues, organs, and organ systems that perform specialized functions.
Benchmark 9-12:
Understands cell differentiation.

Understands the genetic basis for the transfer of biological characteristics from one generation to the next.

Benchmark 6-8:
Knows that the characteristics of an organism can be described in terms of a combination of traits; some traits are inherited and others result from interactions with the environment.
Benchmark 6-8:
Knows that hereditary information is contained in genes (located in the chromosomes of each cell), each of which carries a single unit of information; an inherited trait of an individual can be determined by either one or many genes, and a single gene can influence more than one trait.
Benchmark 9-12:
Knows the chemical and structural properties of DNA and its role in specifying the characteristics of an organism.
Benchmark 9-12:
Knows ways in which genes may be altered and combined to create genetic variation within a species.
Benchmark 9-12:
Knows that genes are segments of DNA molecules, and that inserting, deleting, or substituting portions of the DNA can alter genes.

|
life science |
|
| |
Knows about the diversity and unity that characterize life.
|
|
| |
Knows how organisms are classified into a hierarchy of groups and subgroups based on similarities that reflect their evolutionary relationships (e.g., shared derived characteristics inherited from a common ancestor; degree of kinship estimated from the similarity of DNA sequences).

|
technology |
|
| |
Understands the relationships among science, technology, society, and the individual.
|
|
| |
Benchmark 6-8:
Knows that science cannot answer all questions and technology cannot solve all human problems or meet all human needs.
Benchmark 9-12:
Knows that science and technology are pursued for different purposes.
