Water Magic


You are hurrying to school on your bike, and suddenly your homework falls out of your backpack. Last night was raining so there are puddles everywhere. OH NO! You drop your bike, try to save your paper but you're too late, your paper has colors where your writing was, now you will have to think of an excuse.

In class we were putting papers into a little of water and observing what would happen. However on the papers we put a drawing or a mark in different colors and then take pictures.
Here are some design that came out of my designs:

We had to experiment with water and alcohol, the design I used was 2 dots of red pen and 1 of gray just a little above of the red dots. When I put it into the glass with water, after a few minutes the design I saw was:
Most polar: pink
Most non-polar or least polar : purple/gray (because it is not sticking to the paper so the water is dragging it up) 
Chemical compounds: water : 8


WE KNOW THAT POLAR THINGS ATTRACT TO POLAR AND NON-POLAR TO NON-POLAR. So the higher on the paper, the more non-polar.

Then I did the exact same drawing in a second paper and placed it in alcohol, however I noticed it took much longer for the alcohol to travel up the paper.
Alcohol is less polar than water, so the colors went up slower. However the polar and non-polar colors where the same as for the water. I find it pretty interesting that water can drag colors with itself just like that. 
And, I know that what we did was a chemical reaction, because when we placed some above a special lamp, they glowed (luminescence!).
