different dyes travel up paper at different speeds…the fun of science…

may.  2012

oh the fun things i’m learning as we homeschool.   did i learn these things?  i have no recollection.  but i love learning it all now!

a test to see if the dye is attracted more strongly to the solvent, or to the paper-if attracted stronger to the water, goes farther.  if the dye is attracted stronger to the paper, the dye travels more slowly.

there were two dots, one in the middle of the paper, and one at the top.  the water almost made it to the top of our experiment, but at least we can see which colors the molecules are more attracted to-the solvent or the paper.
