__Purpose__: Which marker will run-off the paper the most.( Grace )

__Hypothesis__: We thought the Vis-a-vis will run-off the second most, Permanent will run-off the least,and the Vis-a-vis color will run off the most.( Grace )

__Materials__:(Derek)

1. Vis-a-vis marker

2. 600 mL beaker

3. Water

4. Pencil

5. Scissors

6. Ruler

7. Permanent marker

8. Filter paper

__Procedure__:(Derek)

1. Cut three pieces of filter paper strips that are about each 12 cm long.

2. Choose a black or brown Vis-a-vis marker.

3. On one of the strips, draw a dark line horizontally along the width of the bottom of the filter paper that is 1.5 cm from the bottom edge.

4. Write your name on the top edge of your strip with a pen or pencil.

5. Repeat Steps # 3and4 using a color of your choice Vis-a-vis marker.

6. Repeat Steps # 3and4 using a color of your choice permanent marker.

7. Put roughly 100mL of waer in your breaker.

8. Fold the top of your filter paper strips, hand your strips over the pencil so that the bottom edges touch the water.

9. Make observations about what you see occurring. Record this qualitative data in a table.

10. Let your strips sit in the beaker for about 5 to 10 minutes.

11. pull strips out and let them dry.

12. Someone from your group should save the strips for later use.

__Quantitative Observations__- Lab results ( Connor M.) Lengths of How Far Colors/Water Rose __Qualitative Observations- ( Connor M) __ When the water came in contact with the green vis-a-vis marker the color changed from green to blue and yellow. The red perminate marker stayed red and also spread the least of the three. The black vis-a-vis marker bled the most but also the color of it bled black but it mistakenly mixed with the green vis-a-vis which would explain the final color of a purple and blue mixed with a little yellow.The green vis-a-vis was a close second to the highest spread of marker.( Connor M )
 * Type of marker || How far color/water rose ||
 * Vis-a-vis marker(black) || 3cm ||
 * Vis-a-vis marker(green) || 3.5cm ||
 * Permanent (red) || 2cm ||

__Analysis:__ The black Vis-a-vis color spread the farthest out of all of them. It did this because of capillary action it made it rise up the paper making the marker spread out into to different colors. The permanent marker spread the least out of them. It did this because permanent marker doesn't come out with water, so it rose the least. The Vis-a-vis black marker went from black to brown. The other Vis-a-vis green color marker went from green to blue and then to yellow, but the permanent marker only went from red to lighter red. Only the Vis-a-vis color had different pigments.( Grace )

__Conclusion__: Our hypothesis was supported the Vis-a-vis color did run-off the most out of all three. The Vis-a-vis color mesured out to 3.5cm long the second closest was the Vis-a-vis was 3 cm long and the Permanent marker was only 2 cm long. Some errors that happened during the experiment was when the paper got wet sometimes they stuck together and blended the colors together. When the colors blended together we had different colors with each paper that didn't belong there. Suggestions for the experiment later on could be testing different colors than three and see which one rose the farthest. ( Grace)
