Biology

While this technique is used in several different science classes, I enjoyed the specificity of the experiment in relation to biological structures. In cell bio lab our class used thin later chromatography to determine the polarity of several different amino acids. Amino acids are the molecules which are the building blocks for proteins. Using a TLC plate and a specific type of developing solution, groups in our classes determined the relative differential migration amounts for specific amino acids. In doing so we were able to determine which of the molecules were polar and which were non polar. While I don't recommend cell bio to non bio major students because of its time commitment and difficulty I do suggest at least checking out a bio class for a gen ed requirement or something along those lines. You might find you enjoy bio enough to make it your major. 

This is our completed TLC plate. Not much to look at but interpreting data is the challenge
