Copper Cycle Lab Checklist
Requirements
Heading
 Single-spaced
 Includes name
 Includes date
 Includes class
 Right aligned
Title
 Centered, bold
 Involves copper & conservation of mass
Background
 Minimum 5 sentences
 Includes all eight vocab words
 Contains at least one sentence linking the
background information to the rest of the lab
 Does not “give away” the ending of the lab
Purpose
 One sentence
 Does not include EXACTLY “To find out what
happens when you perform a series of
reactions, starting with copper metal.”
Materials
 Bulleted list
 Reflects the equipment used by the
experimenter, not just the provided list of
materials
Procedure
 Numbered list
 ALL steps are in the command form
 Reflects the work of the experimenter (is
NOT copied from the lab handout)
 Includes exact masses/volumes added, not
the range listed on the lab handout
Questions?
Data
 Includes observations from all steps
 Observations are organized in a table format
with the procedure steps or some other
easily readable format
 Observations do NOT include inferences or
conclusions
 Includes masses of copper with and without
watch glass at end of lab
Analysis
 Contains a claim related to the location of
copper
 Claim is supported using evidence that
explains all five major chemical reactions in
the lab
 Concludes with reasoning linking final mass
of copper with conservation of mass
Connections to Purpose
 Sentence 1: Purpose directly copied from
Page 1
 Sentence 2: Purpose is met/not met
 2-4 sentences support conclusion and
summarize how the purpose was met
Sources of Error
 Include percent error calculation
 Contains TWO reasons why why the mass of
Cu at the end of the copper cycle is different
than the mass of Cu at the beginning
Larger Context
 3-5 sentences about how the lab relates to
the world.
Other Formatting Requirements

acid, not Sulfuric Acid)
 All chemical formulas have correct subscripts
 Headings are underlined
 Appropriate font (size 12) is used
