Course Description
BSC2010L — Biology I Laboratory (titled variously across Florida institutions as Integrated Principles of Biology I Laboratory, Biology for Science Majors I Laboratory, or Biological Science I Laboratory) is the laboratory companion to BSC2010, the first semester of the science-majors biology sequence in the Florida Statewide Course Numbering System (SCNS). It is a 1-credit lab course meeting approximately 2-3 hours per week, with most institutions accumulating 30 to 45 total contact hours over a 15-week semester.
The course provides hands-on laboratory experiences that reinforce the foundational concepts of BSC2010 lecture: the scientific method, cellular structure and function, biochemistry, energy transformation (cellular respiration and photosynthesis), cell division (mitosis and meiosis), and Mendelian and molecular genetics. Through guided experimentation and inquiry, students develop laboratory technique, quantitative data analysis skills, scientific writing, and critical evaluation of experimental design.
BSC2010L is part of the Florida General Education core requirement for natural science (science majors track) and articulates seamlessly across all Florida public colleges and the State University System under the Statewide Course Numbering System. Students intending to pursue degrees in biology, biomedical sciences, pre-medicine, pre-pharmacy, pre-dental, pre-veterinary, biotechnology, environmental science, or related life-sciences fields take this course in their freshman or sophomore year. The course is offered at approximately 21 Florida institutions including the State College of Florida, Broward College, Florida State College at Jacksonville, Indian River State College, Tallahassee State College, Valencia College, Miami Dade College, and the University of South Florida.

- Laboratory Technician and Research Assistant positions — at hospitals (AdventHealth, Orlando Health, BayCare, Tampa General, Jackson Health), research institutions (Moffitt Cancer Center, Mayo Clinic Florida, Sanford Burnham Prebys, the Max Planck Florida Institute, the Whitney Laboratory for Marine Bioscience, the Florida Hospital Translational Research Institute), and the Florida biotechnology corridor.
Special Information
Articulation and Transfer
BSC2010L is part of the Florida General Education core natural-science requirement (science-majors track) and articulates without loss of credit between any two Florida public colleges and the State University System under the Statewide Course Numbering System. Students who complete BSC2010 + BSC2010L at one Florida public institution will receive equivalent credit at any other for the purpose of completing the Associate in Arts (A.A.) and progressing to upper-division coursework.
Distinction from BSC1010 / BSC1010L (Non-Majors Biology)
Florida public colleges offer a parallel non-majors biology sequence (BSC1010 + BSC1010L, often titled Principles of Biology or General Biology) for students in degree paths that do not require the rigorous science-majors curriculum. BSC1010 will not satisfy the prerequisite for upper-division biology, pre-medical, or biological-sciences-major coursework; only the BSC2010 + BSC2010L sequence does. Students should verify with their academic advisor which sequence is required for their intended degree path.
Course Format
BSC2010L is typically offered as a 2-3 hour weekly laboratory meeting separate from the lecture (BSC2010), which is itself a 3-credit course meeting 3 hours per week. Some institutions offer combined lecture-and-lab sections under the BSC2010C designation; in those cases, BSC2010L is not separately enrolled. Students should verify enrollment requirements with their institutional advisor.
Corequisite Enrollment
Most Florida public colleges require concurrent or prior completion of BSC2010 lecture as a corequisite for BSC2010L. A small number of institutions allow lab to be taken in a separate semester from the lecture, but advance approval is generally required.
Prerequisites
Standard prerequisites include high-school chemistry (or college-level CHM1020 or CHM1030) and college-ready reading, mathematics, and writing placement. Some institutions require or recommend prior or concurrent enrollment in CHM1045 (General Chemistry I). Students should consult institutional catalogs for institution-specific prerequisite requirements.
Time Commitment
Although BSC2010L is a 1-credit course, the time commitment substantially exceeds the credit hour. In addition to the 2-3 hours of in-lab time per week, students should plan on 3-5 additional hours per week for pre-lab reading and quizzes, post-lab analysis, formal lab reports, and exam preparation.
AI Integration
Generative-AI tools (ChatGPT, Claude, Gemini) are increasingly relevant for the data analysis, graphing, and scientific-writing components of this course. Students may find AI tools useful for explaining statistical concepts, debugging Excel formulas, or improving the clarity of lab-report prose. However, the use of AI to fabricate data, generate lab-report text without independent intellectual contribution, or substitute for direct laboratory observation is generally a violation of academic integrity policy. Students must consult the institutional and instructor-specific policy on AI use in their course; expectations differ across Florida institutions and individual instructors. The fundamental skills of experimental design, accurate observation, and quantitative analysis remain irreducibly the student's responsibility.
