Question
Transcribed Image Text:4) A father (80 kg), mother (56 kg), daughter (16 kg) and son (24 kg) try to occupy
seats on the seesaw shown below so that the seesaw is in equilibrium.
Can they succeed? If so, where do they need to sit? Explain your process.
Ability A2: Can construct new representations from previous representations
Needs Work
Representations are created
without mistakes, but there
is information missing, i.e.,
labels, variables.
Adequate
Representations are
constructed with all given
(or understood) information
and contain no major flaws.
Inadequate
Representations are
attempted but use incorrect
information or the
representation does not
agree with the information
used.
Ability D7: Is able to choose a productive mathematical procedure for solving the problem
Needs Work
Inadequate
Correct and complete
mathematical procedure is
described but an for is
made in the calculations. All
units are consistent.
Adequate
Mathematical procedure is
fully consistent with the
design. All quantities
calculated correctly with
proper units. Final answer is
meaningful.
Adequate
Explanation is clear,
detailed, and shows physical
and conceptual
understanding. Explains
both what was done and
why.
A mathematical procedure is
described, but is incorrect
or incomplete, due to which
the final answer cannot be
calculated. Or units are
inconsistent.
Ability F3: Is able to clearly explain their reasoning in words
Needs Work
Explanation is slightly
unclear, missing some
minor information, covers
what was done but is
missing why it was done.
Missing
No attempt is made to
construct a different
representation.
Inadequate
Explanation is incoherent,
incomplete, confusing, or
inconsistent with the work
shown.
Missing
Mathematical procedure is
either missing, or the
