Can I send this out to my group?

Materials:
4 paper clips
1 sandwich baggies
3 dominoes
3 rubber bands
This is to measure if the tension is more on the middle rubberband or the outside rubberbands. Also, this will decide whether measuring from one end of rubberband to the next or the halfway marks are more accurate way of determining force vs length.
Set up:
Take the 4 paper clips and 3 rubber bands. The paper clips being first then a rubber band, attaching the rest and ending with a paper clips.
This should make a chain like the rubberband calibration. Attach the baggy at the end of rubber bands.
Now mark each rubberband with a number 1-3 and put a mark on each and mid-way through the rubber band.
Hang the set of rubberbands with the baggy. First measure from one end of rubber band to the other like in the rubberband calibration.
Then second measure the rubberbands from the marks made half-way, take the ruler and measure from one mark to the next for each rubber band.
That is the first set of data, then you will add a dominoe to the baggy. You will continue this for the force of three dominoes.
Data:
Sketch a graph for each set of rubberbands, force vs. length.
Make a table of the date with the number of dominoes, force, and length of rubber band.

Instructions for the experimenter will end here. The next line will be part of your instructions for the analyzer, and that will come later.

Decide which method could give more accurate answers.

This is good, except that your last line won't be part of your instructions to the experimenter. That line is actually an interpretation.
You can send this, except for the last line, as instructions for the experimenter. The next thing you'll want to address is your instructions to the analyzer. You should be thinking about what that individual will do with the results reported by the experimenter.
