LAST UPDATED SEPTEMBER 3, 2018

Procedures & Policies

All information, guidelines, and deadlines in the table below are subject to
LAB INSTRUCTOR'S DISCRETION
Your lab instructor may choose to modify the posted guidelines & deadlines.
If that happens, do what your lab instructor says, not what the table says.

Some handy resources:

All about UNCERTAINTY
Lab Report Dos & Don'ts


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

 A Thing on a String:

Measurement of Effects; Derivation of Cause

Due: POST-LABS for Lab #1
-- one each per GROUP.

(Instructions for Post-Labs
, etc.,
can be found at the end of the Lab 1 packet.)


A word of advice on
GROUP COLLABORATION:

Make an internal deadline.
Don't just write separate sections. Read, edit, discuss them.

Managed wisely, a work-group does not reduce workload.
It improves quality.

Lab #3B.

B: Video Creation for the Wave Equation

And here's

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.)

Suggested RESEARCH QUESTIONS

(Treat the following as a Group of connected questions; NOT a set of choices):

If waves travel along an x-Axis defined by some 1-D medium
(such as a stretched spring or string), then...

A)
i. What mathematical function describes how the y-Position of
any given particle depends on Time?
ii. In what units are the constants measured; to what physical parameters do these constants refer?

B)
i. What mathematical function describes how the y-Position of
any given particledepends on the
particles's x-Position?
ii. In what units are the constants measured; to what physical parameters do these constants refer?

C)
i. What second-order Differential Equation fully describes wave motion?
ii. How are the individual (single-variable) functions found above related to this Differential Equation?

D)
i. In what way is Wave Motion
similar to Simple Harmonic Motion?
ii. In what way is Wave Motion
different from Simple Harmonic Motion?

BOARD MEETING Beta:

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



Choice 1:
Points of CHARGE

OR

Choice2:
Discovering the
Doppler Effect

Desmos TUTORIAL:

http://www.Desmos.com

--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.

Lab #5A

Steady CIRCUITS--

Getting Introduced

Circuit Components: Meaning & Measurement

Some Sample Student Solutions To Lab 4B!

DUE:

POST-LABS*

FOR LAB #4

*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".

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.
