Policies
•
Attendance is mandatory.
Lateness is not tolerated.
Quizzes will be given at the beginning of the
period. There are no make-ups for quizzes, and no
extra quiz time will be given to students who come late to class.
•
There will be about 12 quizzes during the
semester, each quiz will be based on the previous completed experiments. These quizzes are open
notes.
•
Each person is to write up two
formal lab during the semester. One
from the first half and one from the second half. You may not write up
the same
lab as your partner. Your
lab report
must be handendin on or before 3/15/2011 and 5/16/2011
Lab
reports will not be accepted after 7:50PM on their due day. Each person is to collect
the experimental
data and complete all calculations and associated graphs from each
experiment,
following the guidelines on the back of this page.
This is considered lab work
and is to be neatly done in ink, and turned in no later
then one week after the experiment is completed from your lab notebook. Graphs are to be done on a
computer graphing
program showing results of the appropriate curve fit. If you have
completed the
formal report for a particular experiment, you do not need to hand in
the data
on a spereate sheet of paper.
•
Attendance for each lab is mandatory.
Your final semester letter grade will be
dropped one half letter grade for each lab missed (we do two labs/class
period,
so you would lose one full letter grade if you miss entire lab and do
not make
it up). Make-ups
for labs will be
allowed at the discretion of the instructor (YOU MUST HAVE A
SUBSTANTIAL REASON
FOR MISSING LAB), and will be given only with prior arrangements (SPEAK
TO ME
BEFORE YOU MISS THE LAB).
Lab
Notebook (from wikipedia)
A lab
notebook is a primary record of research. Researchers use a
lab notebook to
document their hypotheses, experiments and initial analysis or
interpretation
of these experiments. The notebook serves as an organizational tool, a
memory
aid, and can also have a role in protecting any intellectual property
that
comes from the research.
Structure
The
guidelines for lab notebooks vary widely between institution and
between
individual labs, but some guidelines are fairly common. The lab
notebook is
usually written in as the experiments progress, rather than a later
date. Many
say that lab notebook should be thought of as a diary of activities
that are
described in sufficient detail to allow another scientist to follow the
same
steps.
Legality
To
ensure that data cannot be easily altered, notebooks with permanently
bound
pages are often recommended. Researchers are often encouraged to write
only
with unerasable pen, to sign and date each page, and to have their
notebooks
inspected periodically by another scientist who can read and understand
it. All
of these guidelines can be useful in proving exactly when a discovery
was made,
in the case of a patent dispute.
Grading
There
will be one formal report, informal lab report on each lab, and about
12 quizzes.
60% Quizzes
20% Formal reports
20% Lab Work and Questions
Final
class letter grades will be earned as follows:

Mr. Croom
Lab Name
Purpose:
This is a
short paragraph on describing the objectives of the experiment. It
should
describe the scenario you are modeling without going into the detail of
the
procedure. Expcite goals of your inviestigation ane what you expect to
learn
from the lab should be stated here.
List of Apparatus:
This section
includes a list of all itemes used during this experiment. If this is
the first
time we have used this apparatus describe what the apparatus is, draw
or
computer generate and image of the object and explain how it works.
Procedure:
What steps
do you take in the lab? This should outline the
procedure you take in
gathering your data. Do not simply copy the procedure from the lab
sheet. Write
down the steps you need to take in the order you need to take them to
arrive at
your results. Make sure to list how you will use the apparatuses listed
above.
The overall procedure should be complete enough that an arbitrary
person could
read your procedure and can perform the lasb as you did it.
Theory:
The theory
is the main body of your paper. In this section write in paragraph
sentence
form the information about your lab. Make sure to include, the
definition of
major terms, the reasoning and connection to the lab of all major
concepts,
make sure tell what the theory says should happen in the lab, and make
sure to
tell the history behind the theory.
This is not
the time to try to rewrite the laws of physics. The theory is factual
based on
the current understanding of the universe. If you have some information
that
defies current law, explain it in the results section of this paper
NEW PAGE
Data:
Charts,
graphs, and tables that include all of your data. If there is more then
one
table or chart, make sure to label them ("Data Table 5-2" ect.) so
that they can be referenced through out your paper. Graphs should be
done
neatly and should contain a large enough scale to interpret all of the
data.
NEW
PAGE
Calculations:
Provide one
calculation for each of the different types of calculations you
preformed. Make
sure to show all steps. An example of this would be:
Total Normal Force
=Total mass of block (kg) * (acceleration due to gravity (m/(s2)) *
sin(of the
angle (radians))
=0.4136 kg (± error) * 9.80 m/s2 * sin (p/2 (±
error) )
= 4.05 N (± propagated error)
Analysis:
Explain
where your error came from and if your data is significantly off,
greater then
5% error; predict what the acceptable values would be.
Results:
In paragraph
sentence form explain anything strange about your data, for example,
any new
laws of physics you may have discovered. Example: If I drop a
ball and a
feather they both drop at the same rate according to the theory. If
your data
didn’t show that then did we forget something. If not did we
discover a new law
of physics?
Then, in a
new paragraph, explain the significance of your data, and what your
data is representing.
In this paragraph explain, what the data is telling you. Interpret your
data!
Finally, in a third paragraph ask any questions you might have about
the lab
you performed.
Remember, if
there is something that doesn’t match your theory, that you
didn’t explain in
the results or analysis and you did not ask about it in the question
paragraph,
then you can expect to lose points.
Questions:
Answer any
questions that were asked on the lab hand out but were not answered
above. The
preferred method for you to do this is to answer the questions in one
of the
sections above, and then parenthetically site is by writing (Q1) or
(Q2)
directly after the sentence but before the punctuation.
Conclusion:
In the
conclusion, evaluate your understanding of the lab. Tell the reader
what you
found interesting. Explain what was new to you and what you took from
the lab.
Evaluate your pre-lab predictions.
