BIOL 103 Introduction to Biology is a 4-credit course at the University of Maryland Global Campus that combines the content of a lecture course with laboratory activities.
UMGC describes it as an introduction to the structure and function of living organisms, aiming to apply the scientific method and use scientific and quantitative reasoning to make informed decisions about experimental results in the biological sciences.
Topics include the chemical foundations of life, cell biology, genetics, evolution, ecosystems and the interdependence of living organisms, along with the scientific method and the impact of biology on society. Laboratory activities emphasize the scientific method.
BIOL 103 fulfills the laboratory science requirement. UMGC states that it is not open to biotechnology or laboratory management majors or to students who have completed BIOL 101 or BIOL 102, and that students may receive credit for only one of BIOL 101 plus BIOL 102 or BIOL 103.
Because concepts and labs run together, the main challenge is workload: keeping up with readings while turning each experiment into a clear report.

What BIOL 103 Covers
| Topic | In plain language |
|---|---|
| Chemical foundations of life | The molecules of life and how they behave |
| Cell biology | Cell structure, membranes, energy and division |
| Genetics | DNA, inheritance and how traits are expressed |

| Ecosystems and interdependence | How organisms interact with each other and their environment |
| Scientific method in the lab | Designing tests, collecting data and interpreting results |
Key Concepts Explained
From Observation to Conclusion
The scientific method links lecture and lab: an observation leads to a question, a hypothesis predicts an outcome, an experiment tests it and the results support or fail to support it.
Example: Observation: potato slices left in salty water go limp. Hypothesis: "If potato pieces are placed in increasing salt concentrations, then they will lose more mass, because water leaves the cells by osmosis." Data: percentage change in mass at 0%, 2%, 5% and 10% salt. Conclusion: if mass falls as concentration rises, the hypothesis is supported, and the point where mass does not change estimates the cells' internal concentration.
Quantitative Reasoning
Many BIOL 103 tasks ask you to calculate percentages, averages or rates and to judge whether differences are meaningful. Percentage change (final minus initial, divided by initial, times 100) lets you compare samples of different sizes.
Biology and Society
UMGC includes the impact of biological knowledge and technology on human societies, so expect to discuss applications such as vaccines, genetic testing or conservation with evidence and balance.
Typical Assignments and How to Approach Them
Follow your syllabus and rubric. Because BIOL 103 combines lecture and lab, work typically includes:
| Assignment type | What it tests | How to approach it |
|---|---|---|
| Lab report | Scientific method and data handling | Hypothesis, methods, results with tables or graphs, then discussion |
| Conceptual assignment | Understanding of biological principles | Explain the principle and apply it to a real example |
| Discussion posts | Engagement and reasoning | Answer directly with evidence and respond to peers |
| Quizzes and exams | Core knowledge | Study lab results alongside the theory they illustrate |
Planning Your Week in a 4-Credit Course
BIOL 103 compresses lecture and lab work into one course, so time planning matters. Reading, discussions, lab activities and reports all compete for the same week. Many students find it helps to read the lab procedure early, complete the hands-on activity mid-week and draft the report while results are fresh.
Keep all lab data in one organized place, with dates and units, so reports are easier to write and later exams easier to revise.
Where Students Get Stuck
- Falling behind. Four credits of lecture and lab move quickly; schedule time for both every week.
- Disconnected lab and theory. Use the lecture concept to explain why your results happened.
- Calculation errors. Show your working and check units.
- Thin discussions. Address errors, limitations and what the results mean.
Study Tips for BIOL 103
- Read the lab procedure before the related lecture material.
- Keep a template for lab reports and reuse it.
- Practice percentage change and averages before your first lab.
- Check each rubric criterion and make sure it is visibly addressed.
