Procedures & Policies

SCROLL DOWN FOR FULL CALENDAR,

BUT FIRST NOTE the following:

ALL DUE-DATES BELOW HOLD
UNLESS/UNTIL OTHERWISE ANNOUNCED

-- IN YOUR INDIVIDUAL LAB SECTION.

The particular lab instructor for your
PARTICULAR LAB SECTION


CAN AND WILL EXERCISE DISCRETION


REGARDING THE DETAILS FOR

LAB SUBMISSION DEADLINES, GRADES, EXTRA-CREDIT ASSIGNMENTS,

and related matters.

 

--> --> -->

--> --> -->


SO: In any apparent conflict between
the information found in the calendar below
and information explicitly provided in your lab section,
explicit section instructions take precedent.

This helps insure that your
intellectual (learning) and academic (grading) experience
actually relate to what is actually happening with you & your colleagues --
who tend to be, we find,
an actual group of actual people working in an actual & specific set of circumstances.

Put another way:
Curricular consistency is to your advantage;
rigid unifomity is not.
We wish you to earn the fairest possible grade --
one that recognizes and takes advantage
of the richly varying talents and dispositions
brought to physics progam
by richly varying individual lab instructors --
and of the unique environment that each one of the lab insttructors
is uniquely equipped to facilitate.

In the event of confusion or concern,
first make an appointment
with your lab instructor;

If not wholly satisfied, then contact Yaverbaum.



If, for any reason, you wish to upload and submit a lab document to Yaverbaum, press the submit button below:

Often, the lab schedule provides you with time
to work through your understanding of the lab
via the drafting of an abstract.

The schedule does not necessarily, however, provide you with the opportunity to receive instructor
feedback on this abstract prior to completing the report.
Such time is by no means a waste.
It is one of many means by which you are being encouraged to make authentic use of
GROUP COLLABORATION.

-- Don't just assign writing tasks to one another;
assign reading/editing/accounting tasks to one another!
Incorporate collective self-feedback into the
Report drafting process.

Managed wisely,
a work-group does not take a given task
and sub-divide it into lower labor allocations;
it takes a given task and scales it up
to higher quality aspirations.

EACH LAB GROUP.

***

Each Formal Report will Include

A FRESH (clean) ABSTRACT --

whether or not the abstract submitted
separately in Lab Week 2
was returned with feedback.

It is expected that the abstract included in this Formal Report will show some development from the first submitted version:

This abstract will accurately reflect
the true contents of
the completed formal report--
as opposed to what was planned/intended.

SOME HELP

with the analysis:.

(This part of the course
can seem very
intimidating at first,
but it's very important and helpful once you work through it.
If you're patient,
you are likely to find
its bark to be worse
than its bite.
And it all connects to the lecture material,
i.e.: helpful for the exam.)

defined by some 1-D medium
(such as a stretched spring or string),
then

BOARD MEETING Beta:

Today's Board Meeting is
Entirely up to your
LAB INSTRUCTOR.



Choice 1:

OR

Choice2:
Discovering the
Doppler Effect

Desmos TUTORIAL:

--All-Purpose
MOST HIGHLY RECOMMENDED Option for
Data Plotting & Curve Fitting

***

LoggerPro TUTORIAL:

-- Provides and Explains a
reliable option for
Data Plotting &
Curve Fitting:

LoggerPro is appropriate and recommended for graphing
ONLY WHEN the data are gathered through LoggerPro itself
AND all other options,
including EXCEL & DESMOS
are, for some reason,
unavailable.

To be clear, LoggerPro is a last resort
for graphing/curve-fitting.
Ideally, it should be used simply
for gathering data into a computer.

DUE:

POST-LABS*

FOR LAB #4B

*Note: Until/unless otherwise notified,
the Post-Lab Assignment for Lab #4B IS:

In at least a paragraph
composed of complete English sentences
from your own words:

Explain how the motion captured
in the very short video below

VJ&SONS

is 1) LIKE Wave Propagation,

2) NOT LIKE Wave Propagation

Lab #5B

Steady CIRCUITS--

Getting Familiar

Circuit Components:
Properties & Relations

* * *

NOTE: The name Lab #5B
means simply
more time to complete
Lab #5A.

Both of the links (A & B) actually point to one and the same document.

The assumption is that each group
will work at its own pace --
stopping wherever appropriate
by the end of Week 5b,
just so long as all procedures contained in the one manual for Lab 5 have been completed
by the end of the Lab Week.

Hence, the work for both weeks proceed according
to one all-inclusive packet,
here entitled "Lab #5".

 

DUE:

FORMAL REPORTS
FOR LAB #4B.

QUALITATIVE ABSTRACT

for Lab #6

* * *

NOTE:

1) Be EXTREMELY careful and aware regarding the two distinct meanings for 'C' used in this lab.

(First, make sure to identify the two distinct meanings.)
The use of one letter to mean both is unfortunate.
One meaning is universal;
the other meaning arises in the use of
Logger Pro software.

2) Whether you finished taking the data for this lab or not, your obligation is to understand the big picture enough to write an abstract as though you had proceeded from start to finish: This will either be ENTIRELY QUANTITATIVE (if you were able to complete all lab-work in the lab) or ENTIRELY QUALITATIVE. You will either consistently include numbers in your abstract or you will consistently leave them out.

The good news, therefore, is that you need not concern yourself with any particular numerical details of data or results that you did not get a chance to collect. If you did not.

The bad news is that you are not allowed to make up or throw in numbers -- or use numbers for the beginning of some thoughts and then have those thoughts drift into non-numerical statements.

SIMPLY AVOID NUMBERS ENTIRELY
OR
DO A FULLY QUANTITATIVE ABSTRACT.

Either way, it's not an easy assignment. But your success will not rely on how far your experimentation had a chance to get.

Suggested Research Questions

for

a lab

regarding

the

DOPPLER EFFECT!

If waves travel
from a source to a receiver
through a medium (such as air)
and the source has
velocity relative to the medium,

A) How will the wave frequency
as measured in the source reference frame relate to the frequency
measured in the receiver reference frame?

[The above is a central qu,estion
that applies in general:
for all instances of the Doppler Effect.]

B) As measured in the
receiver reference frame,
How does the wave frequency
as the source approaches the receiver
relate to the wave frequency
as the source recedes from the receiver?

[The above is a particular research question
that applies specifically to a simulation we often use for our investigations/experiments/research here.

C)
i. Why/How can a source and a receiver measure two different values for the frequency of one wave?
ii. Which frequency measurement, if either, is 'actually' correct?

   

Note: All assignments are 1) highlighted, 2) DUE the day on which they appear and 3) hyper-linked as we progress through the year.
