Title: Properties Of Water Lab ( Brock )

purpose: **__(____Rob Boughton)__** To find out what properties of water effect the clot on each of the paper slips. Hypothisis: **__(Rob Boughton)__**


 * 1. I predict that the water will reach the line on the strip.
 * C2. I predict that the h2o will reach the dot and will spread out.
 * Permenent. I preadict that the water will reach the line but wont spread out.

Materials: **(Emily Wegenke)**
 * Vis-a-vis marker
 * 600mL beaker
 * Water
 * Pencil
 * Scissors
 * Ruler
 * Permanent Marker
 * Filter Paper

Procedure: ( Brock )
 * 1) Cut three pieces of filter paper strips that are about 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 half of the bottom of 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 numbers 3 and 4 using a color of your choice Vis-a-vis marker.
 * 6) Repeat steps numbers 3 and 4 using a color of your choice permanent marker.
 * 7) Put roughly 100 ml of water in your beaker.
 * 8) Fold the top of your paper strips, hang your strips mover the pencil so that the bottom of the strips touch the water. Don’t submerge your line in the water.
 * 9) Make observations about what you see occurring. Record the qualitative data in a table.
 * 10) Let your strips sit in the beaker for about 5 to 10 minutes.
 * 11) Pull the strips out and let them dry.
 * 12) Someone from your group should save the strips for later use.

Observations: **(Rob Boughton)** True Colors
 * Brown || Orange Black & Pink colers in it. ||
 * Red || All pink. ||
 * Sharpie || Just Blue. ||


 * Marker || Observations || Drawings and observations. ||
 * Brown || Bottom half is wet and the ink is spreading. ||  ||
 * Blue || Bottom half is wet and the right side is spreading a lot. ||  ||
 * Yellow || Its wet but it is spreading around. ||  ||

Analysis: ** (Emily Wegenke) ** The marker that showed evidence of the most color in the ink would be the brown vis-a-vis marker. This marker had the most color in the ink because to be able to make the color brown you have to add a bunch of other colors to the ink. For example it showed little tints of yellow, red, blue and of course brown. The second marker that would have shown the most color in the ink would be the blue permanent marker. Even though blue is a primary color doesn't mean that there could be other colors in the ink. In the blue marker it had yellow, so the person before probably used a blue and yellow marker with means there could be yellow ink on the marker. For the strip that spread the farthest on the filter paper it would be the brown vis-a-vis marker. This marker spread the farthest because of the cohesion property. The cohesion property states that: when water particles touch other particles it "connects” to it. In simpler terms when the water reached the marker line it absorbed into it causing it to spread further out. Our red vis-a-vis marker was the marker that barley spread at all. The red vis-à-vis marker spread the least furthest out probably because it wasn’t deep enough in the water so there for neither the cohesion or adhesion property had a chance to take effect.

Conclusion: ( Brock ) We performed this experiment to find out the different properties of water and how they work. Two out of the three hypotheses were right in our experiment. We discovered that the red vis-a-vi marker didn’t spread out and our hypothesis was wrong. We knew this because the red marker did not spread out on the paper and there were no other colors but red. Also we found out the Blue permanent marker spread out and that is what we predicted was right. On the strip there were many colors which proved that it spread out. The brown vis-a-vis marker spread out which seemed to be what we predicted so we were right. We could tell because many colors make up brown and when it spread out it showed that. Some errors we made in our experiment was we submerged the line under the water and the color leaked out so we had to perform it again. It could be improved by putting just the very tip of the paper in the water not a lot so we could see it climb up better.
