Students will demonstrate their understanding of the importance of curiosity, honesty, open-mindedness, and skepticism in their own efforts to understand how and why universal phenomena exist and occur. |
By the end of grade 2:
a. Ask questions about the world around them and exhibit willingness to seek answers to selected questions by carefully observing, experimenting, and predicting the outcome of an investigation.
By the end of grade 5:
a. Keep records of investigations and observations and not alter the records.
b. Distinguish observations from ideas and speculations and predications about observations.
c. Offer reasons for findings and also consider reasons suggested by others.
d. Support statements with facts found in books, articles, and other resources.
e. Identify when comparisons might not be accurate or appropriate because some conditions are different.
f. Question
scientific claims based on vague attributions (such
as "Leading doctors say...")
or on statements made by people outside the area
of their particular expertise.
By the end of grade 8:
a. Keep scientific records of investigations which reflect the importance of reporting honestly, clearly, and accurately.
b. Question the value of arguments based on very small samples of scientific data, biased samples, or samples for which there was no control sample.
c. Identify
the flaws of arguments based on the faulty, incomplete,
or misleading use of numbers, such as instances in which
(1) average results are reported, but not the amount
of variation around the average, and (2) a percentage
or fraction is given, but not the
total sample size (as in "9 out of 10 dentists recommend...").
d. Suggest alternative ways of explaining scientific data and criticize arguments in which data, explanations, or conclusions are represented as the only ones worth consideration, with no mention of other possibilities.
e. Recognize that there may be more than one reasonable way to interpret a given set of scientific findings.
f. Draw independent conclusions based on data, using critical reasoning to construct models, rationally defend conclusions, and recognize the validity of other positions.
g. Understand that hypotheses are valuable if they lead to fruitful investigations, even if the hypotheses turn out not to be true.
By the end of grade 12:
a. Exhibit traits that show an understanding of how honesty, curiosity, transparency, and skepticism affect the progress of scientific inquiry.
b. Offer different explanations for the same scientific evidence, and explain why it is not always possible to tell which explanation is best supported.
c. Know that scientists do not have models that explain all phenomena, and that current models range from the proven - the Earth is round - to the speculative - cancers are viral.
d. Critically analyze and evaluate experimental designs for accuracy, including variables, controls, adequate data sampling, and logical conclusions and suggest design improvements when appropriate.

d. Analyze and evaluate scientific data to draw a valid conclusion.
e. Write and describe coherent accounts of scientific activities and alternative interpretations of the results.
f. Understand the importance of verbal accuracy and explicit statement of critical assumptions when stating a position.
By the end of grade 12:
a. Choose appropriate summary statistics to describe group differences, always indicating the spread of the data as well as the scientific data's central tendencies.
b. Make and use tables, charts, graphs, and scale drawings to make scientific arguments and claims in oral and written presentations.
c. Participate in group discussions on scientific topics by restating or summarizing accurately what others have said, asking for clarification or elaboration, and expressing alternative positions.

Students will be familiar with the character of scientific knowledge and inquiry and how it is achieved. |
By the end of grade 2:
a. When a science investigation is repeated, the results should be consistent.
b. Explain why accurate descriptions are important in science.
c. Explain why, in doing science, it is often helpful to work with a team and to share findings with others.
d. Know that tools such as thermometers, hand lenses, and rulers aid inquiry by gaining more information.
By the end of grade 5:
a. Describe some of the many different forms of scientific investigation.
b. Offer justifiable explanations when similar scientific investigations do not produce exactly the same results.
c. Explain why clear and active communication is an essential part of doing science, including informing others about scientific work and exposing ideas to criticism.
d. Explain why scientists use technology in investigations, including to increase their power of observation and to measure and compare accurately.
e. Offer some examples of old scientific knowledge that is still applicable today, and explain that new scientific knowledge is still being discovered.
By the end of grade 8:
a. Describe why (such as to explore new phenomena, check previous results, compare theories) and how (by collecting evidence, reasoning, devising hypotheses, and creating explanations) scientists conduct investigations.
b. Explain why and how (for example, by repeatedly and independently replicating experiments) scientists determine if experimental results are reliable.
c. Understand that if more than one variable changes at the same time in an experiment, the outcome may not be clearly attributable to any one variable, and that sometimes scientists can design research to account for this.
d. Explain how scientists try to prevent their experiments from bias in what is observed, missed, and concluded in investigations (for example, through independent studies).
e. Understand and follow scientific ethical norms in conducting research with animals and humans who are unable to make fully informed choices (such as very young children).
By the end of grade 12:
a. Exhibit understanding that a change in the scientific view of how the world works is occasionally major, but is more often a small modification of prior knowledge, and that these new ideas often encounter vigorous criticism.
b. Use hypotheses to guide choices of what data to pay attention to, what additional data to seek, and how to interpret both new and previously available data.
c. Understand that progress in scientific under-standing often manifests itself in more reliable explanations and more accurate predictions, and is achieved by testing, revising, and sometimes rejecting, old and new theories.
d. Explain why scientists often control conditions in experiments, and what they do when controlled conditions are not possible.
e. Explain how and why scientific teams seek out the possible sources of bias in their investigations' hypotheses, observations, data analyses, and interpretations, and follow this model in the student's own work.
f. Explain why science uses practices such as peer review and publication.
g. Describe how and why new ideas in science can be limited and influenced, including cultural and historical context, and how history in turn has been shaped by science.
h. Explain how choices for scientific research can be influenced by funding, which can come from sources such as federal government agencies, industry, private foundations, the World Bank, the International Development Bank, non-governmental organizations, and the European Union.
i. Explain how and why ethical considerations can limit scientific research.
