Missing one piece of
information.
1
Missing two or more
pieces of information.
Two or more
background concepts
are incorrectly
described or missing.
Hypothesis
Hypothesis is in
“if…then…because” format,
includes all necessary
information, and is based on
logical predictions.
Materials
Bullet point list that is titled
and includes quantitative
amounts of supplies.
One background
concept is incorrectly
described or missing.
Correctly defines
almost all relevant
vocabulary terms.
Hypothesis is in
“if…then” format,
includes most
necessary information,
and is based on
somewhat logical
predictions.
Bullet point list that is
titled but lacks some
quantitative amounts.
If procedure is in students’
own words, it contains only
minor errors. If taken from
lab handout, procedure is
cited correctly.
Some steps are vague
or unclear but overall
procedure describes
how experiment was
conducted.
Data table containing
observations is complete,
correctly labeled, and
contains all necessary units.
Some observations are
incomplete or
irrelevant AND/OR one
data table requirement
is missing or incorrect.
At least 5 of 8 sections
of the conclusion are
correctly addressed.
Specific data is referred
to but some relevant
observations may be
missing.
Report contains many
grammatical or spelling
errors. Two formatting
requirements may be
missing or incorrect but
lab report must be
typed.
Procedure
Demonstrates thorough
understanding of
concepts investigated in
the lab. Student included
and correctly cited
outside research.
3
Includes title, class name,
group members’ names, and
date.
Demonstrates thorough
understanding of concepts
investigated in the lab.
Correctly defines all relevant
vocabulary terms.
Procedure is in paragraph
form, 3rd person, and in
past tense. Includes clear
and concise statements
that include quantitative
values. Easy to follow.
Data and
Observations
Conclusion
Student correctly
addresses all sections of
the conclusion. Student
refers to observations to
support conclusions.
Student correctly addresses
almost all sections of the
conclusion. Student refers
to observations to support
conclusions.
Grammar,
Spelling, and
Formatting
Report contains few
grammatical or spelling
errors. Report is typed in
12pt Times New Roman
or Arial font, doublespaced, and headings are
correctly formatted.
Report contains some
grammatical or spelling
errors. One formatting
requirement may be missing
or incorrect but lab report
must be typed.
Hypothesis is missing
necessary
information, in the
wrong format, or
based on flawed
predictions.
Materials section is
missing, incomplete,
or lacking all
quantitative
amounts.
Procedure contains
significant errors, is
missing, or is cited
incorrectly.
Some observations
are incomplete or
irrelevant AND/OR
two or more data
table requirements
are missing or
incorrect.
Fewer than 5 sections
are correctly
addressed. Data is
not referenced.

hypothesis? Did any data not match your
predictions based on solubility rules?
