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.

Safety Regulations:

    • Gloves
