=Are Permanent Markers Really Permanent?=

=Introduction/Hypothesis= If you apply different solutions to permanent markers then the color will come off because the chemicals in the solutions are breaking down the pigments in the color of the markers. =Annotated bibliography for background information=

I used this site to help plan my experiment. It helped me learn what the judges are looking for in an experiment. It was very inciteful in how to conduct the experiment I was doing. []

=Materials list= -Black Sharpie Markers -Black Bic Markers -Black Marks-A-Lot Markers -Vinegar -Rubbing Alchohol -Water -Fabric X3 -Plastic X3 -Paper X3

=Procedure= 1. Draw a thick with marker across each testing surface ( Paper, Plastic & Fabric) 2. You will need to do this with each type of marker 3. Divide the line into three parts by drawing two vertical lines on the testing surface 4. Apply a few drops of water to one section of the plastic, a few drops of vinegar to another, and a few drops of rubbing alcohol into another. 5. Repeat this for each type of marker. 6 Record your observations. =Variables and Controls= Independent Variable: Type of marker and the solutions being put onto The factor YOU change to see the results. The "if" part of your hypothesis. Dependent Variable: The factor that hopefully changes as a result of the independent variable. The "then" part of your hypothesis. Controls: Factors that would skew your results, but they don't because you kept them constant. =Data recordings and pictures= =Marks-A-Lot=


 * || Plastic || Paper || Fabric ||
 * Water || None taken off || None taken off || None taken off ||
 * Rubbing Alcohol || Color taken off, thin layer still remaining || Color spread and thined in places || Color spread ||
 * Vinegar || None taken off || Small ring of color taken off || None taken off ||

=Bic=


 * || Plastic || Paper || Fabric ||
 * Water || Water sat on top of the marker almost as if it was water resistant || None taken off || Spread small amount of color, water sat on top of marker ||
 * Rubbing Alcohol || color was taken off mostly, little remained || Color spread largely, and was almost removed in a few spots || Color was spread ||
 * Vinegar || Small strip of color removed || None taken off || None taken off, but the vinegar sat on top of the marker ||

=Sharpie= == =Charts and graphs= =Conclusions= What conclusions can you make with the data your collected? Not just your final conclusion... your intermediate findings are conclusions, too. Build your final conclusion on your intermediate conclusions. Finish by answering your big question and stating whether you proved your hypothesis. =Sources of Error=
 * || Plastic || Paper || Fabric ||
 * Water || None taken off || None taken off || None taken off ||
 * Rubbing Alcohol || Sharpie was taken off || Color was spread around || Color was spread around ||
 * Vinegar || Little was taken off || Moved small amouts of color around || Moved color a little bit ||
