NSES Content Standard Unifying Concepts
and Processes:
Evidence, models and explanation Grades K-12, page 117 Scientific explanations incorporate existing scientific knowledge and
new evidence from observations, experiments, or models into internally
consistent, logical statements. Different terms, such as "hypothesis,"
"model," "law," "theory," and "paradigm" are used to describe various types
of scientific explanations. As students develop and as they understand
more science concepts and processes, their explanations should become more
sophisticated. That is, their scientific explanations should more frequently
include a rich scientific base, evidence of logic, higher levels of analysis,
greater tolerance of criticism and uncertainty, and a clearer demonstration
of the relationship between logic, evidence, and current knowledge.

Grades 6-8, page 299
Notice and criticize the reasoning in arguments in which (1) fact and
opinion are intermingled or the conclusions do not follow logically from
the evidence given, (2) an analogy is not apt, (3) no mention is made of
whether the control groups are very much like the experimental group, or
(4) all members of a group (such as teenagers or chemists) are implied
to have nearly identical characteristics that differ from those of other
groups.

Suggest alternative ways of explaining data and criticize arguments
in which data, explanations, or conclusions are represented as the only
ones worth consideration, with no mention of other possibilities. Similarly,
suggest alternative trade-offs in decisions and designs and criticize those
in which major trade-offs are not acknowledged.
Science for All Americans The Nature
of Science
Chapter 1, page 5
Scientists do not work only with data and well-developed theories.
Often, they have only tentative hypotheses about the way things may be.
Such hypotheses are widely used in science for choosing what data to pay
attention to and what additional data to seek, and for guiding the interpretation
of data. In fact, the process of formulating and testing hypotheses is
one of the core activities of scientists. To be useful, a hypothesis should
suggest what evidence would support it and what evidence would refute it.
A hypothesis that cannot in principle be put to the test of evidence may
be interesting, but it is not likely to be scientifically useful.
