The Biomaterials Lab (BML) at Rice University hosted a summer biotechnology camp in collaboration with the Rice Office of STEM Engagement (R-STEM). This is one of BML's outreach initiatives, and it was designed to engage high school students from various independent school districts. The camp was organized into two groups, each consisting of approximately 30 high school students, and offered a structured curriculum over the course of a week, focused on foundational and applied topics in life sciences.
Participants were introduced to various fundamental techniques and concepts in biotechnology, including DNA extraction, gel electrophoresis, and the study of biomaterials. The instructional content was carefully developed to balance theoretical understanding with laboratory-based experimentation, enhancing student engagement and comprehension.
A key component of the program involved the introduction of rheology and scientific imaging within the BML. Students explored the properties of non-Newtonian fluids and were introduced to the principles of rheological measurement using a TA Instruments Hybrid Rheometer. These concepts were initially presented through interactive demonstrations utilizing common household materials such as cornstarch slurry and ketchup. Students then conducted quantitative experiments to measure viscosity changes and gain insight into the behavior of complex fluids under varying shear conditions. These activities provided a gateway to understanding the importance of rheological characterization in biomedical applications, such as injectable hydrogels and tissue engineering.
In addition to rheology, students were introduced to advanced imaging techniques, with a particular emphasis on scanning electron microscopy (SEM). Through hands-on training sessions, students learned the fundamentals of microscopy and operated a desktop SEM under guided supervision. They imaged various samples, including table salt, copy paper, pollen grains, and human hair, and observed their surface microstructures at high resolution. This activity highlighted the role of imaging in materials characterization and biomedical research, offering students an understanding of how such tools are used in scientific investigation.
Overall, the summer camp served as an effective model for STEM outreach by providing high school students with a comprehensive and interactive introduction to biotechnology and biomaterials science. Participants gained practical laboratory skills, developed a deeper understanding of scientific principles, sparking an interest in pursuing STEM fields.
