My Abstract/Introduction:
I meet everything in proficient column

 Introduction begins with an interesting
opening statement that makes the reader
want to keep reading (motivation- why do we
care about the problem and results?)
 Links hypothesis to other research that has
been done for bonding
 Approach is clear: how did you go about
solving or making progress on the problem,
what variables did you control, ignore, or
measure?
 Take home message is clear and includes
the main learning from the lab/ engineering
project
 Conclusion: what are the implications of your
answer? (do you notice any patterns, does
your data help support the understanding of
this topic of chemistry?)
 Includes a description of Hess’s Law and
how it relates to hot/cold packs

Essential question or problem stated
(what problem are you trying to solve?)



Hypothesis presented
Scientific principals explained so that
it is apparent student understands the
basics of endo and exothermic
processes in the use of hot/cold packs,
the purpose of MSDS in creating the
product, the relationship between the
specific heat equation and heat of
solution(enthalpy) in creating a hot/cold
pack, and how the first law of
thermodynamics relates to hot/cold
packs
Results: Findings are included What
were the results of your engineering
project, did your hot/cold pack meet the
requirements? Why or why not?

I am missing
only one or
two non-bold
elements from
the Proficient
column.
1. QUESTION or PURPOSE: Write the purpose very clearly, think about what problem you are trying to
solve.

2. Scientific principals are explained in student-friendly terminology (not duplicated from textbook or
teacher notes). Make sure to define chemistry terms that are not commonly used in normal
conversational language. It is apparent the student understands the basics of endo and exothermic
processes in the use of hot/cold packs, the purpose of MSDS in creating the pack, the relationship
between the specific heat equation and heat of solution(enthalpy) in creating a hot/cold pack, and how the
first law of thermodynamics relates to hot/cold packs

3. Answer your purpose/ question, what is the answer? Clearly explain how your findings might fit into
a trend (pattern). Does your data help support this topic of Chemistry?
