Length of thick rubber band chain vs. length of thin chain
You opposed two rubber band chains, measuring the length of each at a variety of different tensions.

What is the slope of your graph of thin vs. thick rubber band lengths?
****
I took two points on the graph at random (111,19.5) and (85.7, 11) which is equal to 25.3/8.5 which equals 2.9
#$&*
By how much does your graph deviate from linear?
****
It is very close to linear, does not deviate much at all
#$&*
If you fit a good smooth curve to the trend of your data points, does its slope appear to increase or decrease?
****
increase
#$&*
If you fit a good straight line to your first three data points, what is its slope?
****
For this question, (90,13.5), (92,14.3), and (91.5,13.4) are my points. I took random points on my straight line which were (88,12.5) and (90,13.5) which gave me a slope of 2.
#$&*
If you fit a good straight line to your last three data points, what is its slope?
****
I did the same as above but this time I picked out the points on my straight line in between my last 3 points which were (102,12) and (105,18) which is .5
#$&*
If your chain of thin rubberbands was half as long, what would you expect the slope of the graph to be?
****
It would double the slope
#$&*
How long would the chain of thick rubberbands have to be to result in a slope of 1?
****
The thin rubberband and the thick rubber band would have to be the same
#$&*
If the thin rubberbands were twice as thick, how do you think that would affect the slope of your graph?
****
It would cut the slope in half.
