Title:( Jonah ) Properties of water lab

Hypothysis:( Casey ) If the water is able to reach the vis a vis marker then the marker will wash away. If the water is able to reach the permanent marker then the marker won't wash away.

Purpose:( Ben ) The Purpose of this experiment was to test the properties of water on vis-a-vis markers and a permanent marker; we wanted to see how the markers reacted to cohesion and adhesion.

The Materials:( Ben )
 * Vis-a-vis marker
 * 600 mL beaker
 * Water
 * Pencil
 * Scissors
 * Ruler
 * Permanent market
 * Filter paper

The Procedure( Evan ):


 * 1) Cut three strips of paper that are about 12 cm long.
 * 2) Choose a black or brown vis-a-vis.
 * 3) On a strip of paper draw a line that is 1.5cm away from edge.
 * 4) Repeat step 3 with a different vis-a-vis.
 * 5) Repeat step 3 with a black sharpie.
 * 6) Put around 100mL of water in a beaker.
 * 7) Fold the top of your papers and hang them from a pencil.
 * 8) Make and write observations and take picutres.
 * 9) Let your papers sit until the pigment gets close to the pencil.
 * 10) Take pictures of the papers for more observations.
 * 11) Find out that which markers ink went the farthest and which one didn't move.

Observations( Jonah ) Vis-a-vis marker:Brown Within a minute has begun to turn brown with splocches of red,pink and orange on it; It stayed the same. Perminant marker: Stayed the same the whole time. Green perminant marker: Turned bright yellow and green. with splocches of red,pink and orange on i t; It stayed the same. || Turned bright yellow and green within about a minute. It also stayed the same. || Once writen it stayed the same and never changed. ||

Analysis: ( Evan ) Q: Which marker's pigment went the farthest? A: For us the green vis-a-vis markers pigment went the farthest. This was because adhesion brought the water together while the cohesion was making the water stick and move up the paper, hence why the color was pick up by the water. This was capillary action.

Q: Which marker moved the least or didn't move at all? A: The permanent marker because the sharpie did not have any proporties that would let it get washed away by the water so the cohesion only happend to the paper not the permanent marker.

Q:Which markers do you think are made of more than one color? A: Well the vis-a-vis markers because the pigments or colors spread out but the black sharpie didn't.

Conclusion:( Ben ) In conclusion, our hypothesis was correct, we thought the vis-a-vis markers would be the only markers to run, and the permanent marker would not spread out or wash away. We may have made some small mistakes, for instance, we could have worked to not let the parchment paper get submerged in the water and we could have also tried harder to keep a stable amount of water touching the paper at all times. If we could further experiment into the properties of water, we would like to look at other types of writing materials and markers and observe how they react to the properties of water.
