Working in teams, students selected a physiological response to study and conducted experiments measuring variables such as heart rate, blood pressure, grip strength, and memory retention. After crafting a research question and outlining a procedure, they gathered volunteers, collected data, and performed statistical analysis to determine whether their results showed significant effects.
Biomedical Innovations teacher Cory Brackett highlighted the rigor of the assignment and how it represents the culmination of students’ four-year journey.
“As the final class in the PLTW Biomedical Science pathway, they used knowledge and tools from the previous courses to implement their study. Students are being given a glimpse at upper-level college science courses and it allows them to understand the amount of rigor and testing that goes into scientific studies that we hear about in our everyday lives.”
During presentations, students shared their research process, analysis, and findings with their classmates. Their peers then posed thoughtful questions about methodology, challenges, and potential improvements, fostering an environment of scholarly dialogue that mirrors university-level scientific defense.
Principal Leandrea Slayton emphasized the value of authentic learning moments that surfaced during the process.
“One of the things I appreciated most about the presentations was that some of the experiments failed to support their hypothesis, yet students still learned in the process and could articulate factors that would have improved or changed the outcomes. This is the level of problem-solving and critical thinking we hope every student leaves Liberty with.”
At the end of the project, teams reflected on what they gained from this hands-on experience.
A group consisting of Jill Bean, Grace Dean, Hannah Jockers, and Kara Campoy shared:
“While researching and completing the necessary steps for our experiment, we learned a lot about the process of designing and running an effective experiment.”
Another team, Roshni Bhavsar, Evelyn Orozco-Alvarez, Adaleigh Woodman, and Bella Zepeda, highlighted the lasting impact of the skills they developed:
“The information we learned regarding statistical analysis pertains to subjects far beyond this science course. We are sure to use this knowledge in our futures.”
The PLTW Biomedical Innovations presentations not only showcased students’ scientific knowledge but also demonstrated their perseverance, curiosity, and readiness for the challenges ahead. These senior scientists leave Liberty High School prepared to think critically, ask big questions, and contribute meaningfully to the world around them.
