First Class: Dancing Milk

In the first class of Honors Biology we created an experiment to explain why milk with food coloring "dances" with a drop of soap.

First, Eddie and I hypothesized that the intensity of the reaction was based off of the amount of fat in the milk.  To test our theory we made the milk a variable and tested different types while keeping the soaps a constant.  The different milks we used were whole, 2%, and skim.  Using the same soaps in these three different milks we found that whole milk had the fastest and longest lasting reaction while skim had the least.  To make sure that this result was caused from the difference in milk we used Dawn, Sun, Ajax (bleach), and Palmolive Orange dish soap in all 3 and found that the different soaps made little to no difference in reaction.  From this we concluded that the amount of fat in the milk did affect to what extremity the food coloring would "dance."
