My PBL Project
Introduction:
Are Sharpies really permanent markers? I will draw a line on different surfaces (wood, glass, and fabric) with a sharpie and test which solution will remove the line.
Materials:
Piece of Wood
Fabric
Glass
Bleach
Non-Acetone Nail Polish Remover
Baking Soda
Sharpie Permanent Marker
Gloves
Cotton Swabs
Water
Scotch Tape
Alcohol Wipes
Table Cloth
Procedures:
1. Gather Materials
2. Put on gloves
3. Draw 5 lines with the Sharpie on the Wood, Glass, and Fabric and label with Scotch Tape
4. Dip cotton swab into Nail Polish Remover
5. Rub cotton swab on wood for 5 seconds
6. Dip cotton swab into Water then Baking Soda
7. Rub cotton swab on wood for 5 seconds
8. Dip cotton swab into Water
9. Rub cotton swab onto Wood
10. Dip cotton swab into Bleach
11. Rub cotton swab on wood for 5 seconds
12. Rub alcohol wipes on the wood
13. Repeat steps 3-10 for Glass and Fabric
Data:
Below the data depicts which item worked the best to remove the Sharpie from the surface.
Scientific Principle: By the results of the experiment Non-Acetone Nail Polish Remover and Alcohol Wipes erased the permanent marker from almost all of the surfaces. Both Non-Acetone Nail Polish Remover and Alcohol Wipes have Isopropyl Alcohol, which is a type of polar alcohol. Alcohol can dissolve polar and nonpolar substances. Permanent markers are nonpolar, therefore Alcohol Wipes an Non-Acetone Nail Polish Remover can remove permanent marker.
