Last March 25th, our 2nd-grade high school “A” students stepped into the world of genetics with a fascinating hands-on experiment in the school laboratory. Under the guidance of Biology teacher Ms. Iowana Maltes and Laboratory Manager Ms. Pamela Tobar, students explored the microscopic building blocks of life—DNA—using an unexpected but familiar subject: a banana.
In our science labs, students do not just observe; they become scientists, actively engaging with the world around them. This experiment allowed them to extract and examine real DNA, bringing abstract concepts to life in an exciting and interactive way.
With keen focus and enthusiasm, students followed each step of the DNA extraction process, from mashing the banana to breaking down cell walls and isolating genetic material. They carefully carried out procedures such as cell lysis and DNA precipitation, witnessing firsthand the delicate strands of life’s code emerge before their eyes.
What made this experience even more enriching was its bilingual approach, with the collaboration of Mr. Marcos from the English Immersion Program, the activity was conducted in both English and Spanish, reinforcing scientific knowledge while enhancing language skills, exploring the building blocks of life firsthand in our school lab, encouraging seamless collaboration and exchange of ideas in both languages.
Beyond the scientific principles, this activity cultivated essential skills—precision, patience, and teamwork—preparing students for future academic and professional challenges. The session also sparked discussions about DNA’s role in heredity, biodiversity, and the commonalities shared by all living organisms.
This engaging lab experience left students inspired and eager to explore more scientific discoveries. As they continue their educational journey, we hope this hands-on approach to learning ignites a lifelong passion for science and inquiry.
