A Biology Laboratory Exercise Using Macromolecule Assays to Distinguish Four Types of Milk

One of the drawbacks of cookbook-style laboratory exercises for General Biology courses is that students are not challenged to develop skills in scientific reasoning, such as formulating hypotheses and designing and carrying out experiments. Several traditional laboratory curricula include exercises...
