  1. S.T.E.M. Fair 2013-2014

  2. QUESTION • Are permanent markers permanent?

  3. 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.

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

  5. Procedure

  6. Materials • 5 - 5cm x 5cm pieces of fabric • 5 Different detergents • 5 cups

  7. 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

  8. 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

  9. 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.

  13. 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 1.8marker 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.
