Research Project Description:
This summer I worked on a research project investigating lung surfactant collapse mechanisms using AFM (Atomic Force Microscopy). Lung surfactant is a surface active molecule we have in our lungs to help with the absorption of oxygen in the lungs. Premature infants have not developed their own lung surfactant and can have respiratory distress syndrome. The overall goal of the research group is to develop an artificial lung surfactant system to be injected into premature babies to aid them in breathing. The overall goal is divided into many separate research projects. The goal of the research I did over the summer was to determine how specific monolayers collapse. l used an LB trough to collapse different monolayer samples and I looked at the collapsed structures under AFM.

Curriculum Project Description:
During my RET 1 experience I spent 6 weeks in a chemical engineering lab working with lung surfactant. This time in the lab was spent doing hands-on experiments where I was manipulating equipment and samples. Previously in my earth science classes we have not had "hands-on" lab experiences. My curriculum module was to develop hands-on lab experiences that could be incorporated into the standards-based earth science curriculum. These labs will be spread out over the entire year. I will be using a lab activity every week or two. These labs have been designed so that my students will gain experience manipulating lab equipment, gathering data, analyzing their data, and writing about their results.
