Introduction

The Independent variable in this investigation was ________________.  We measured this variable by: (describe what you did to get values- discuss any uncertainties in measurement)

 The Dependent variable in this investigation was ________________.  We measured this variable by: (describe what you did to get values- discuss uncertainties in measurement)

 Constants for this investigation are: _____________________ (give names and values with units, discuss uncertainties)

Data

Data Table showing all collected data and graphed data.

Graph(s) of Data with appropriate Statistics (each person sketch graphs and write statistics, print-out one copy of Graphical analysis sheet for the group).

 Relationship
Our results show a (proportional, linear, equal) relationship between (x-axis item) and (y-axis item). The found relationship compares (favorably, unfavorably) with the expected result of (textbook equation) which shows a (proportional, linear, equal) relationship. 

Y-Intercept
The y-intercept of our found equation is (y-intercept value, could be negligible) meaning when (x-axis item) is zero, (y-axis item) is (y-intercept value, could be negligible). 

For the next part you use option 1 (qualitative) OR option 2 (quantitative) depending on if you can make a numerical comparison or not.

OPTION 1: This y-intercept is (reasonable/unreasonable) because (*talk about how is reasonable or not reasonable*).

OR (If you have numbers to compare)

OPTION 2: The expected results predict a beginning value of (y-intercept of textbook equation- or real world value), our results have an error of _____ % with this prediction

% error calculation:  | predicted-ours| /predicted * 100 = % error

*If error < 10 % say:  This error is small, it could be attributed to… (*be specific-give details, show intelligence)

*If error>10% say:  The error could be due to…. (be specific- give details; DO NOT SAY “Human Error”—in addition to not being specific enough it implied incompetence*).  

Slope
The slope of our found equation is (slope value), this tells us how much (y-axis item) changes for every unit of (x-axis item). The slope tells us (*give the meaning of the slope, it usually has something to do with the constants of the lab*).

For the next part you use option 1 (qualitative) OR option 2 (quantitative) depending on if you can make a numerical comparison or not.

OPTION 1: This slope is (reasonable/unreasonable) because ……

OR (If you have numbers to compare)

OPTION 2: The expected results predict a rate of change of (slope of textbook equation- or real world value), our results have an error of _____ % with this prediction

% error calculation:  | predicted-ours| /predicted * 100 = % error

*If error < 10 % say:  This error is small, it could be attributed to… (*be specific-give details, show intelligence)

*If error>10% say:  The error could be due to…. (be specific- give details; DO NOT SAY “Human Error”—in addition to not being specific enough it implied incompetence*).  

Any extra questions particular to a certain lab would be answered at the end of  your relationship, y-intercept, and slope discussion.....
