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.

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.

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.
