Mr.Roberts Are Permanent Markers Permanent? Conclusions Hypothesis Research Purpose Design Materials Procedures Data
Analysis Bibliography Purpose The purpose of this experiment is to determine if various manufacturer's permanent markers are truly permanent. Hypothesis If a marker is permanent then it cannot be erased by any solvents. Research Design Exponent Variables

Constants:
Sharpie marker
BIC marker
Prismacolor marker

Dependent Variables:
Paper
Cardboard
Plastic bottle

Independent Variable:
Acetone
Rubbing alcohol
Nail polish remover Materials Markers:
Sharpie
BiC
Prismacolor
Removers:
Acetone
Rubbing Alcohol
Nail Polish Remover
Applicators:
Q-tip
Paint Brush Procedures Step 1a:
Use a permanent black Sharpie to mark on a piece of paper, apiece of cardboard, and a plastic bottle.
Step 1b:

Black BIC Marker

Applied to Paper Attempt to Remove with Acetone
Applied to Cardboard Attempt to Remove with Rubbing Alcohol

Black PrismaColor Marker

Applied to Paper Attempt to Remove with Acetone
Applied to Cardboard Attempt to Remove with Rubbing Alcohol
Applied to Plastic Bottle Attempt to Remove with Nail Polish Remover Conclusions All permanent markers can be permanent or removed depending upon the medium it is written on. This experiment indicates that the more porous the material written on is more easily removed with acetone and nail polish remover.

This experiment only used three of the permanent markers that are available.
These conclusions may differ based upon the other types of permanent markers. Bibliography The History of Pens and Pencils
