 * __Title:__** Properties of Water Lab (** Montana Barnard **)

(** Montana Barnard **)
 * __Purpose:__**To find out what the effects of water are on a color Vis-a-vis (red),Vis-a-vis (black), and a permanent (black) marker.

__**Hypothesis:**__If we submerge a small poration of a paper strip in water and place a black dot about 1.5cm from the edge the water will creep up the surface of the paper. The black Vis-a-vis marker will perform the best. (** Montana Barnard **) (** Montana Barnard **)
 * __Materials:__**
 * 1) Vis-a-vis marker (black, red)
 * 2) 600ML beaker
 * 3) Water
 * 4) Pencil
 * 5) Scissors
 * 6) Ruler
 * 7) Permanent marker (black)
 * 8) Filter paper
 * 9) Camera

__**Procedure:**__
 * 1) Cut three strips of paper 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 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 PENCIL.
 * 5) repeat steps 3 and 4 using a color of your choice vis a vis marker, then with a black permanent marker.
 * 6) Put roughly 100 mL of water into a beaker
 * 7) fold the top of your filter strips, hand your strips over the pencil so that bottom edges touch the water. DO NOT SUBMERGE THEM!
 * 8) let them soak for 5-10 minutes
 * 9) pull out & allow them to dry, record results

**Analysis: (Paige) **
The black vis-a-vis marker traveled the farthest up the paper. This marker allowed for cohesion more than the other marker. The black permanent marker traveled the fartherest up the paper. This marker did not allow for cohesion. The two markers that are made of more than one pigment are the black vis-a-vis and the colored vis-a-vis. I could tell this because when the markers bled they spread into many different colors, which showed the pigments.

‍**Conclusion: (Paige) **
Each hypothesis we made was correct. We predicted that both vis-a-vis would bleed, and they both did. Our pictures and our observations prove this. One error that was made during the experiment was that we didn't leave the pencils over tthe beaker long enough. We also didn't submerge them all evenly in the water. These all could be fixed by more precision, and understanding the lab better. For more research on this topic, it cold be improved if could have more trials and more precision.
