Inspiring Future Scientists at Lewisville High School

At Lewisville High School, unseen aspects of science are becoming real and intriguing. Dr. Rebecca DeLozier, a science teacher at LHS, sees this happen daily thanks to her LEF grant funded by CoServ.

“The world of science thrives on discovery, and so should our classrooms,” DeLozier said. “Seeing is believing, and by harnessing the power of hands-on learning, we aim to ignite a passion for science and empower the next generation of scientific leaders.”

Throughout the school year, about 310 students across 12 class sections used materials provided by the grant to observe microscopic cells and tissues, cultivate plant growth, and develop critical lab skills. These scientific explorations fostered real-world application and curiosity about careers in STEM fields.

Curriculum integration began in October, with pathology slides used in Pathophysiology and AP Biology to study tissues and cancer.

In December, Pathophysiology introduced electrophoresis, a technique used to separate and study molecules, to explore pathogen identification and genetic disorders.

“Students [are] able to see actual DNA fragments separated by electrophoresis, providing a tangible connection to the building blocks of life,” DeLozier said.

In January, AP Biology used the plant cart to study photosynthesis and respiration.

“Students successfully designed and conducted inquiry labs to expose algae to various light conditions and were able to analyze and interpret their results, linking light conditions to metabolic consequences,” DeLozier said.

From February onward, Microbiology utilized prepared bacteria slides allowing students to visualize pathogens that cannot be cultivated in the lab serving as references for student-led laboratory investigations.

“Students directly linked cell cycle disruptions and uncontrolled cell growth to tumor formation…, showing a strong ability to link abstract concepts to practical examples,” DeLozier said.

During March and April, electrophoresis labs focusing on DNA fingerprinting and antibiotic resistance were key activities in AP Biology and Microbiology, heavily utilizing supporting equipment like micropipettes and centrifuges.

“By allowing students to see these concepts come to life, we can bridge the gap between theory and reality, fostering critical thinking skills and a lifelong love of learning,” DeLozier said.

DeLozier noted the clear and measurable success of this grant project. 92 percent of students ended the school year pipetting with precision, a skill crucial for lab research. LHS science teachers saw a 34 percent increase in post-quiz scores following project implementation. Each student using electrophoresis equipment understood appropriate operating procedures, ensuring a safe learning environment. Students developed critical thinking abilities through lab notebook analysis, observation of scientific argumentation, and open-ended question response. Lab notebooks showed a consistent increase in the ability to explain connections between lab activities and relevant scientific topics such as antibiotic resistance and genetic engineering.

“This project aims to do more than equip our labs; it’s about empowering future generations of scientists, healthcare professionals, and informed citizens.” DeLozier said. “By immersing students in the exciting world of hands-on science, we prepare them for potential STEM careers and foster a lifelong appreciation for the wonder and relevance of science in our daily lives.”

This project, made possible by the CoServ Charitable Foundation Grant, has enhanced student learning and engagement in several scientific capacities.
