Analyze scientific data by using, interpreting, and comparing numbers in several equivalent forms, such as integers, fractions, decimals, and percents.

#### S7CS3b

Use the mean, median, and mode to analyze a set of scientific data.

#### S7CS3c

Apply the metric system to a scientific investigation that includes metric to metric conversion. (i.e. centimeters to meters)

#### S7CS3d

Draw conclusions based on analyzed data.

#### S7CS3e

Decide what degree of precision is adequate, and round off appropriately.

#### S7CS3f

Address the relationship between accuracy and precision and the importance of each.

#### S7CS4

Use tools and instruments for observing, measuring, and manipulating equipment and materials in scientific activities.

#### S7CS4a

Use appropriate technology to store and retrieve scientific information in topical, alphabetical, numerical, and keyword files, and create simple files.

#### S7CS4b

Use appropriate tools for measuring objects and/or substances.

#### S7CS4c

Learn and use on a regular basis standard safety practices for scientific investigations

#### S7CS5

Use the ideas of system, model, change, and scale in exploring scientific and technological matters.

#### S7CS5a

Observe and explain how parts can be related to other parts in a system such as predator/prey relationships in a community/ecosystem.

#### S7CS5b

Understand that different models (such as physical replicas, pictures, and analogies) can be used to represent the same thing.

#### S7CS6

Communicate scientific ideas and activities clearly.

#### S7CS6a

Write clear, step-by-step instructions for conducting particular scientific investigations, operating a piece of equipment, or following a procedure.

#### S7CS6b

Write for scientific purposes incorporating data from circle, bar and line graphs, twoway data tables, diagrams, and symbols.

#### S7CS6c

Organize scientific information using appropriate simple tables, charts, and graphs, and identify relationships they reveal.

#### S7CS7

Question scientific claims and arguments effectively.

#### S7CS7a

Question claims based on vague attributions (such as Leading doctors say...) or on statements made by people outside the area of their particular expertise.

#### S7CS7b

Identify the flaws of reasoning that are based on poorly designed research (i.e., facts intermingled with opinion, conclusions based on insufficient evidence).

#### S7CS7c

Question the value of arguments based on small samples of data, biased samples, or samples for which there was no control.

#### S7CS7d

Recognize that there may be more than one way to interpret a given set of findings.

#### S7CS8

Investigate the characteristics of scientific knowledge and how that knowledge is achieved

#### S7CS8a

When similar investigations give different results, the scientific challenge is to judge whether the differences are trivial or significant, which often requires further study. Even with similar results, scientists may wait until an investigation has been repeated many times before accepting the results as meaningful.

#### S7CS8b

When new experimental results are inconsistent with an existing, well-established theory, scientists may pursue further experimentation to determine whether the results are flawed or the theory requires modification

#### S7CS8c

As prevailing theories are challenged by new information, scientific knowledge may change.

#### S7CS9

Investigate the features of the process of scientific inquiry.

#### S7CS9a

Investigations are conducted for different reasons, which include exploring new phenomena, confirming previous results, testing how well a theory predicts, and comparing competing theories.

#### S7CS9b

Scientific investigations usually involve collecting evidence, reasoning, devising hypotheses, and formulating explanations to make sense of collected evidence

#### S7CS9c

Scientific experiments investigate the effect of one variable on another. All other variables are kept constant.

#### S7CS9d

Scientists often collaborate to design research. To prevent this bias, scientists conduct independent studies of the same questions

#### S7CS9f

Accurate record keeping, data sharing, and replication of results are essential for maintaining an investigators credibility with other scientists and society.

#### S7CS9g

Scientists use technology and mathematics to enhance the process of scientific inquiry.

#### S7CS9h

The ethics of science require that special care must be taken and used for human subjects and animals in scientific research. Scientists must adhere to the appropriate rules and guidelines when conducting research.

#### S7L1

Investigate the diversity of living organisms and how they can be compared scientifically.

#### S7L1a

Demonstrate the process for the development of a dichotomous key.

#### S7L1b

Classify organisms based on physical characteristics using a dichotomous key of the six kingdom system (archaebacteria, eubacteria, protists, fungi, plants, and animals).

#### S7L2

Describe the structure and function of cells, tissues, organs, and organ systems.

#### S7L2a

Explain that cells take in nutrients in order to grow and divide and to make needed materials.

#### S7L2b

Relate cell structures (cell membrane, nucleus, cytoplasm, chloroplasts, mitochondria) to basic cell functions.

#### S7L2c

Explain that cells are organized into tissues, tissues into organs, organs into systems, and systems into organisms.

#### S7L2d

Explain that tissues, organs, and organ systems serve the needs cells have for oxygen, food, and waste removal.

#### S7L2e

Explain the purpose of the major organ systems in the human body (i.e., digestion, respiration, reproduction, circulation, excretion, movement, control, and coordination, and for protection from disease).

#### S7L3

Recognize how biological traits are passed on to successive generations.

#### S7L3a

Explain the role of genes and chromosomes in the process of inheriting a specific trait.

#### S7L3b

Compare and contrast that organisms reproduce asexually and sexually (bacteria, protists, fungi, plants & animals).

#### S7L3c

Recognize that selective breeding can produce plants or animals with desired traits.

#### S7L4

Co-Requisite Content

#### S7L4a

Demonstrate in a food web that matter is transferred from one organism to another and can recycle between organisms and their environments.

#### S7L4b

Explain in a food web that sunlight is the source of energy and that this energy moves from organism to organism.

#### S7L4c

Recognize that changes in environmental conditions can affect the survival of both individuals and entire species.

#### S7L4d

Categorize relationships between organisms that are competitive or mutually beneficial.

#### S7L4e

Describe the characteristics of Earths major terrestrial biomes (i.e. tropical rain forest, savannah, temperate, desert, taiga, tundra, and mountain) and aquatic communities (i.e. freshwater, estuaries, and marine).

#### S7L5

Examine the evolution of living organisms through inherited characteristics that promote survival of organisms and the survival of successive generations of their offspring.

#### S7L5a

Explain that physical characteristics of organisms have changed over successive generations (e.g. Darwins finches and peppered moths of Manchester).

#### S7L5b

Describe ways in which species on earth have evolved due to natural selection.

#### S7L5c

Trace evidence that the fossil record found in sedimentary rock provides evidence for the long history of changing life forms.
