Investigation and Experimentation
7. Scientific progress is made by asking meaningful questions and conducting careful investigations. As a basis for understanding this concept and addressing the content in the other three strands, students should develop their own questions and perform investigations.
M.C.1: Structure and function in living systems
M.C.1.a Living systems at all levels of organization demonstrate the complementary nature of structure and function. Important levels of organization for structure and function include cells, organs, tissues, organ systems, whole organisms, and ecosystems.
M.C.1 Structure and function in living systems
b. All organisms are composed of cells–the fundamental unit of life. Most organisms are single cells; other organisms, including humans, are multicellular.
d. Specialized cells perform specialized functions in multicellular organisms. Groups of specialized cells cooperate to form a tissue, such as a muscle. Different tissues are in turn grouped together to form larger functional units, called organs. Each type of cell, tissue, and organ has a distinct structure and set of functions that serve the organism as a whole.

M.C. 2 Reproduction and heredity.
M.C. 2.a 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.
M.C.2 Reproduction and heredity
c. Every organism requires a set of instructions for specifying its traits. Heredity is the passage of these instructions from one generation to another.
M.C. 2 Reproduction and heredity.
d. Hereditary information is contained in genes, located in the chromosomes of each cell. Each gene carries a single unit of information. An inherited trait of an individual can be determined by one or by many genes, and a single gene can influence more than one trait. A human cell contains many thousands of different genes.
M.C.2 Reproduction and heredity
An animal can be described in terms of a combination of inherited traits.
M.C.3 Regulation and Behavior
d. An organism's behavior evolves through adaptation to its environment. How a species moves, obtains food, reproduces, and responds to danger are based in the species' evolutionary history.
M.C.5 Diversity and adaptation of organisms
a. Millions of species of animals, plants, and microorganisms are alive today. Although different species might look dissimilar, the unity among organisms becomes apparent from an analysis of internal structures, the similarity of their chemical processes, and the evidence of common ancestry.
M.C.5 Diversity and adaptation of organisms
c. Extinction of a species occurs when the environment changes and the adaptive characteristics of a species are insufficient to allow its survival. Fossils indicate that many organisms that lived long ago are extinct. Extinction of species is common; most of the species that have lived on the earth no longer exist.
M.D.2 Earth’s History
b. Fossils provide important evidence of how life and environmental conditions have changed.
M.G.1 Science as a human endeavor
a. Women and men of various social and ethnic backgrounds–and with diverse interests, talents, qualities, and motivations–engage in the activities of science, engineering, and related fields such as the health professions. Some scientists work in teams, and some work alone, but all communicate
b. Science requires different abilities, depending on such factors as the field of study and type of inquiry. Science is very much a human endeavor, and the work of science relies on basic human qualities, such as reasoning, insight, energy, skill, and creativity–as well as on scientific habits of mind, such as intellectual honesty, tolerance of ambiguity, skepticism, and openness to new ideas.

M.U.2 Evidence, models, and explanation
a. Evidence–Evidence consists of observations and data on which to base scientific explanations. The goal is to help students use evidence to understand interactions and predict changes.
c. Explanations–Explanations provide interpretation, meaning, or sense to objects, organisms, or events. Explanations incorporate existing scientific knowledge and new evidence from observations, experiments, or models into internally consistent, logical statements, such as hypotheses, laws, principles, and theories. The goal is to help students create explanations which incorporate a scientific knowledge base, logic, and higher levels of analysis.
M.U.4 Evolution and Equilibrium
a. Evolution–Evolution is a series of changes, some gradual and some sporadic, that account for the present form and function of objects, organisms, and natural and designed systems. The goal is for students to recognize that objects & systems change over time.
Patterns can be used to identify cause and effect relationships.
Complex and microscopic structures and systems can be visualized, modeled, and used to describe how their function depends on the shapes, composition, and relationships among its parts, therefore complex natural structures/systems can be analyzed to determine how they function.
In multicellular organisms, the body is a system of interacting tissues and organs, specialized for particular body functions.
Growth and Development of Organisms
Animals engage in characteristic behaviors that increase the odds of reproduction.
Information Processing
Sense receptors transmit signals along nerve cells to the brain, resulting in behaviors.
Genes control the traits of the organism. Changes (mutations) to genes can affect the structures and functions of the organism and thereby change traits.
The fossil record documents the existence, diversity, extinction, and change of many life forms throughout the history of life on Earth.
Anatomical similarities and differences between various organisms living today and between them and organisms in the fossil record, enable the reconstruction of evolutionary history and the inference of lines of evolutionary descent.
Adaptation by natural selection acting over generations is one important process by which species change over time in response to changes in environmental conditions.
Scientists and engineers are guided by habits of mind such as intellectual honesty, tolerance of ambiguity, skepticism, and openness to new ideas.
Science assumes that objects and events in natural systems occur in consistent patterns that are understandable through measurement and observation.
Science knowledge is based upon logical and conceptual connections between evidence and explanations.
