Science experiments

 

 We have a book of science experiments, and I told the kids that they could each choose one to do today.  Sarah picked chromatography, because she knew there was food coloring involved.  She mixed some red and green food coloring together and put a drop on a strip of paper towel.  Then she hung it over a cup of salt water and watched the colors separate.

 

Noah chose an experiment about capillary action, because it involved defying gravity.  He put one end of paper towel strip in a bowl of water, and taped the other end to the rim of a tall cup.  Then we watched the water climb up the paper towel and talked about how the paper towel is made of tiny wood fibers.
