AUTHORS:
Be sure to put the full name of all group members here.
Spell the names correctly (-1)
Always list all authors who contributed to work, even if you submitted your own report (-2)

INTRODUCTION:
You didn't mention the importance of the experiment.
Your statement of importance is confusing or incorrect
Your statement of importance is not explicit (-1)
Your statement of importance is too specific (should be broader than referring to learning something about pieces of tape) (-1)

METHOD:
Missing diagram
Incomplete or vague diagram (-1)
Incomplete or vague procedure (-1)
Incorrect procedure (details follow) (-5)
Not detailed enough (-2)

DATA:
Missing Freebody Diagram
The freebody diagram is incomplete (-2)
The freebody diagram is unclear (don't redraw methods diagram with labels) (-1)
Use arrows in Word or another method to draw more accurately (-1)
At least one force is mislabeled on your freebody diagram (-1)
Your angle theta is confusing/misleading (-2)
Your angle is not shown on the diagram (-2)
Data is present but not organized into a table (-1)
Some units missing in table (-1)
Wrong Number of Significant figures (-1)
Did not list data assumed for calculations (such as g or mass of tape)
Did not list all data assumed for calculations (-1)
Did not show three trials (ie, did not list repeated measurements)
Some data given doesn't correspond to any label in diagrams (r=?) (-1)

ANALYSIS:
Missing fundamental physics principles
Missing initial equations
Incomplete mention of fundamental physics principles (-1)
Equations clustered in one place and hard to decipher (-1)
Missing explicit reference to approximation or assumptions (-2)
You should approximate the mass and charge of the tape centered on the tape, not at the bottom (-1)
Wrong value for r-hat (-1)
Missing equation relating charge on tape to electric force
Missing a "q=?" line
Your "q=?" line is incorrect
You shouldn't double your electric force (-2)
Missing calculations
Missing precision for q
No explanation of error
Poor explanation of error (-2)
Overlooked obvious error, such as tape sticking to measuring devices, etc (-1)
Analysis was incomplete: missing steps (-2)
Analysis was incomplete: unclear progression of steps (-1)
Analysis was difficult to follow (use subscripts or handwrite and scan, please) (-1)
Analysis was difficult to follow (don't do math in prose form) (-1)
Fundamental equations listed aren't fundamental enough (-1)
Starting Equations have numbers in them (-1)
Overstatement of precision of q: it's only to one sig fig, and an approx.(-1)
You confused approximations with measurements (-3)

CONCLUSION:
Charge density calculation wrong (should be Charge/Area) (-2)
Charge density calculation should be in C/cm^2 to compare with given value
Charge density calculation not explicitly shown (-2)
Your density was larger than the max before sparking (should have set off alarm) (-2)
No comment about charge density compared with maximum possible (-1)
No explicit response to maximum reasonable charge question (-1)
Confusing statement about maximum reasonable charge (-1)
Entire section missing (no credit)

REFLECTION:
Overlooked obvious error, such as tape sticking to measuring devices, etc (-1)
No mention of questions raised by experiment (-2)
Overestimation of accuracy of this experiment: lack of accuracy is innate (-2)

STYLE:
A few spelling and/or grammar errors (-1)
Parts of your lab contained sentence fragments that made it confusing (-1)
Some units missing (-1)
Missing any use of units
No mention/use of significant figures
You kept too many sig. figs. (-2)
You kept 2 sig. figs.  Should really be 1.  (-1)
Don't repeat similar calculations; show once and make a table for all results (-1)
Poor or imprecise wording throughout, such as misuse of physics-related terms or presentation of statements that don't make sense(-2)
Please organize by section as indicated in the rubric (-1)

NOTE: You assumed that each piece of tape had the same charge on it.  You needed to assume this, but most of you didn't explicitly claim this as an assumption.  I didn't take points off for it, but be aware of it.
NOTE: In Conclusions, you should indicate thought about how the excess charge compares to the total number of atoms in the tape.
