=Group 2 Lab Reports= __**Title:**__ Properties of water //( **Zach** ) // __**Purpose:**__ To find out if there is cohesion and/or adhesion is present when the markers touch the water. (Abbey) __**Hypothesis:**__ I think that the orange permanent marker willl not get smeared but the black and green vis-a-vis markers will smear. (Abbey)

__**Procedures:**__ mikey


 * 1 cut three pieces of filter paper strips that are about each 12cm 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 f the filter paper that is 1.5cm from the bottom edge
 * 4 write your name on the on the top edge of your strip with pen or pencil
 * 5 repate 3 and 4 3 more with the other markers
 * 6 put about 100ml of water in your breaker
 * 7 fold the top of your filter paper strips hand your strips over the pencil so that the bottom edges touch the water
 * 8 make observation about what you see occurring record this qualitative data in a table
 * 9 let your strips sit in the beaker for about 5,10min
 * 10pull strips out and let them dry
 * 11 someone from your group should save the strips for later use
 * 12 take pictures of strips

__** Analysis: **__ (Abbey)

__**Conclusion:**__ ( //** Zach, Abbey, and Mikey) **//
 * 1) The green vis-a-vis marker ink traveled up the filter paper the farthest. This is because this marker ink is soluable in water. The marker's ink smeared up the paper demonstrating adhesion.
 * 2) The orange permanent marker traveled up the filter paper the least. This is because this marker is not soluable in water. the marker's ink did not smear up the paper not demonstrating cohesion nor adhesion.
 * 3) The green vis-a-vis marker and the black vis-a-vis marker both showed that they were made of more than one pigment when they smeared up the filter paper. I knew this because the green vis-a-vis marker showed blue and yellow and the black vis-a-vis marker showed brown and dark blue when smeared up the paper.

Our hypothesis was correct. The orange marker, as we said in our hypothesis, did not smear, which is an example of niether cohesion or adhesion. The vis-a-vis markers, as we also said in our hypothesis, did smear, and this is an example of adhesion. Some errors that may have occured is that we didn't measure the water to exactly 100mL and we didn't dip the strips of paper in the water the exact same length every time. One way to improve the experiment is to measure exact every single time for everything. In the end, we learned that adhesion is present when the vis-a-vis markers smeared
