b Physical Sciences Concepts:
The student produces evidence that demonstrates
understanding of the structure and properties of matter….
 
 Throughout the
work, the student explained the relationship between mass, volume,
and density, often with a level of detail revealing excellent conceptual
understanding. There is also ample evidence that the student appreciated
the relevance of density in everyday situations.
a Scientific Thinking: The
student frames questions to distinguish cause and effect; and identifies
or controls variables in experimental and non-experimental research
settings.
 Here
and throughout, the work displays evidence of appropriate scientific
thinking and use of experimental data to reach conclusions.
e Scientific Thinking: The
student identifies problems; proposes and implements solutions;
and evaluates the accuracy, design, and outcomes of investigations.
 
 The student
continually evaluated and critiqued the appropriateness of the experimental
design and the accuracy of the measuring process, and described
the situations in which the techniques employed would be most effective.
f Scientific Thinking: The
student works individually and in teams to collect and share information.
Comparison of
results among groups provided partial confirmation of results.
 The student
has acknowledged the benefits of collaboration.
a Scientific Tools and Technologies:
The student uses technology and tools
(such as traditional laboratory equipment…) to…measure
objects directly, indirectly…, and with appropriate consideration
of accuracy and precision.
 
The student used traditional methods.
Comparison of
results among groups was an effective method for judging accuracy.
e Scientific Communication:
The student communicates in a form suited
to the purpose and the audience, such as by writing instructions
that others can follow….
