These are the
"methods" that you will use to determine the properties of your polymers. They combine several skills into a procedure for doing
something. Measuring an intrinsic viscosity is a good example. These

Lab Report Format
This link (it works) gives you a format for the lab write-up. This
format is required in terms of overall content (ie, sections and
organization) but will vary in detail for each lab.
Not quite as "in-depth" as a lab report, these are the reports you write after performing a method found in LabNotes.
The following are in development. Sorry!
The most basic
component of lab work
are the "skills" you learn: how to weigh, measure temperature and volume,
make up accurate-concentration solutions. These notes are designed to
help you review or learn these crucial skills: use them! You can't
run a marathon if you don't know how to walk yet.
actually the kinds of
projects or composite experiments that you do in research. You put
together two or more methods with a sprinkling of skills to answer some
fundamental question you need or want the answer to: "How do Tg, Tm and
crystallinity vary in nylon copolymers?" is a good example. We will
pursue several "techniques" at this level during the next nine months.
This will give you first-hand experience in how to organize your time for
implementing and coordinating various methods needed for a given
technique: this is not a cookbook exercises. Even I (heaven
forbid) don't know the answer to the questions we will ask. Doesn't that
give an "edge" to the lab you haven't seen before? There's no right
answer; how in the world can you figure out how to fudge your data so you
get a better grade?
