In the laboratory, students can actively explore concepts and experience the nature of scientific research. We have devised a 5-wk laboratory project in our introductory college biology course whose aim was to improve understanding in five major concepts that are central to basic cellular, molecular biology, and genetics while teaching molecular biology techniques. The project was focused on the production of adenine in Saccharomyces cerevisiae and investigated the nature of mutant red colonies of this yeast. Students created red mutants from a wild-type strain, amplified the two genes capable of giving rise to the red phenotype, and then analyzed the nucleotide sequences. A quiz assessing student understanding in the five areas was given at the start and the end of the course. Analysis of the quiz showed significant improvement in each of the areas. These areas were taught in the laboratory and the classroom; therefore, students were surveyed to determine whether the laboratory played a role in their improved understanding of the five areas. Student survey data demonstrated that the laboratory did have an important role in their learning of the concepts. This project simulated steps in a research project and could be adapted for an advanced course in genetics.

Many biology students are drawn to medically oriented topics. This lab activity engages students with medical interests in botany. I find that students are interested in how plants can have medical applications, for example in pharmaceuticals. Several volatile oils of plants, such as thyme, oregano, tea tree, and black pepper oils, have been found to have antibacterial, antifungal, or antiviral properties. To further their interest in the plant kingdom, teachers can have students test a variety of essential oils for effectiveness as antibiotics. This activity requires only minimal microbiology technique and is appropriate for high school through introductory college biology and botany courses.
