Genetic mutations provide valuable tools for analyzing biochemical pathways in yeast. In this module, students use deletion mutants to analyze the steps in methionine biosynthesis in Saccharomyces cerevisiae. At the end of this module, students will be able to:understand and use the correct genetic nomenclature for genes, proteins and mutant strainsexplain how genetic screens are used to isolate mutant strains with particular phenotypesdistinguish various met deletion strains by their ability to grow on selective media containing different sulfur sources and by their appearnace on indicator mediapredict how mutations in various MET genes will affect the intracellular concentrations of intermediates in the methionine biosynthesis This module is part of a semester-long introductory lab class, Investigations in Molecular Cell BIology, at Boston College.

This exercise posits a hypothetical situation: you would like to purchase land that will provide your family with opportunities to fish and swim in a stream on your property. Additionally, you would like the land to afford some privacy. In order to find such a place, you need to locate land for sale that has a stream running through it and you want to confirm that the stream water is clean. The following activity illustrates how one can locate land with particular characteristics and also assess surface water quality for local bodies of water. The data you will use might pertain to any location where streams flow through residential areas.

Students are challenged to think as biomedical engineers and brainstorm ways to administer medication to a patient who is unable to swallow. They learn about the advantages and disadvantages of current drug delivery methods—oral, injection, topical, inhalation and suppository—and pharmaceutical design considerations, including toxicity, efficacy, size, solubility/bioavailability and drug release duration. They apply their prior knowledge about human anatomy, the circulatory system, polymers, crystals and stoichiometry to real-world biomedical applications. A Microsoft® PowerPoint® presentation and worksheets are provided. This lesson prepares students for the associated activity in which they create and test large-size drug encapsulation prototypes to provide the desired delayed release and duration timing.

The purpose of this brief (~15 minutes) activity is for students to directly observe some of the unique properties of water that are the result of hydrogen bonds, such as capillary action, adhesion, cohesion, and surface tension. Students will compare the behavior of water to that of vegetable oil, a non-polar liquid. I have created an activity handout that can either be given to directly to the students or used as a guide by the instructor. It includes vocabulary terms and a discussion "answer key" that should be edited if given directly to students. There is also an "extension activity" that addresses the concept of immiscible solutions.

In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes. By observing these changes, learners show that dark materials absorb and reemit the energy contained in light more readily than light-colored materials. Learners can also distinguish energy absorbed and reemited by radiation, convection, and conduction by comparing the behavior of black, white, and silver objects. This resource guide includes detailed explanation of the phenomenon and background information about liquid crystals.

Geological processes at the mid-ocean ridges are responsible for the bulk of the Earth's heat loss and volcanic activity. The compositions of materials erupted at these locations, dominantly mid-ocean ridge basalts (MORB's), have profound implications for the inner workings of the Earth's mantle, the construction of oceanic crust, and global plate tectonics. In this exercise, students replicate a portion of a classic paper on MORB geochemistry [Klein and Langmuir, 1987] , but using a much larger global geochemical dataset downloaded from the PETDB database. Through a series of activities and questions, students are encouraged to think about the petrologic and geodynamic processes controlling the composition of Earth's most abundant volcanic rocks.

In this activity, students use the virtual lab to create a 0.025M glucose solution from a standard 1M glucose solution. First, they calculate the correct volumes of 1M glucose solution and water to mix together to create the final 0.025M solution. Next, they prepare the solution using the appropriate glassware. Students can check to see if their procedure was correct using the concentration viewer in the solution info panel.
