QUESTION Are permanent markers permanent?
![Page 3: S.T.E.M. Fair 2013-2014](https://reader035.vdocuments.us/reader035/viewer/2022062323/568163bb550346895dd4d427/html5/thumbnails/3.jpg)
Hypothesis I hypothesize that permanent markers
are permanent. The Sharpie will not come off the fabric . I believe this because the label says it is permanent and permanent is permanent.

Purpose The purpose of my investigation is to
determine if the Sharpie is permanent or not permanent.

Variables Manipulated – type of solvent Responding – the amount of marker
remaining Constant - size of fabric, amount of solvent ,
cups , soaking time - 24 hours, and Sharpie

Directions 1. Gather materials 2. Cut five pieces of 5cm x 5cm fabric out 3. Mark the five pieces of fabric with a Sharpie 4. Label one cup Bleach - fill with 200 mL of
bleach 5. Label one cup Soap and Water - fill with 200
mL of soap and water 6. Label one cup Oxi Clean - fill with 200 mL of
Oxi Clean 7. Label one cup Wisk - fill with 200 mL of Wisk
8. Label one cup Resolve - fill with 200 mL of
Resolve

Directions 9. Place one sharpie marked fabric in each
cup. 10. Soak for over night. 11. Remove fabric from each cup. 12. Rate each on a scale from 1 to 5 for
amount of Sharpie still remaining on fabric with 1 being nothing left and 5 being all left.
13. Repeat steps 2-11 for four more trials. 14. Calculate the average removal rate for
each solvent.

Conclusion My hypothesis was incorrect.
Permanent markers are not permanent . Oxi Clean had an average of 4.2 marker removed. Soap and waters had an average 4.8 marker removed. Bleaches had an average 1.8 marker removed. Wisk had an average of 4.0 marker removed. Resolve had an average of 3.6 marker remove. If I had to do this again, I think I would use different fabric to see if the fabric was a factor in my results.
