GCU BIO-220: Environmental Science
BIO-220 examines human impact on natural resources (ecosystems, water, energy, populations, and pollution) as a popular lab-free science option for non-science majors at GCU. The course leans on applied exercises like ecological-footprint assessments and environmental surveys alongside the standard discussion-and-assignment rhythm.

What makes it hard
It's friendlier than the anatomy sequence, but the science vocabulary is real (biomes, nutrient cycles, energy systems), and the assignments expect scientific reasoning, not opinion essays about the environment. Students who treat it as a current-events course get caught when questions hinge on the underlying processes.
What you'll cover
- • Ecosystems and biomes
- • The scientific method in environmental science
- • Water resources and pollution
- • Energy: fossil fuels and renewables
- • Human population dynamics
- • Conservation and resource management
The BIO-220 study guide
How to study for GCU BIO-220, step by step.
- 1
Learn the processes under the headlines
BIO-220 questions hinge on mechanisms (nutrient cycles, energy flows, population curves), not environmental opinions. For each topic, make sure you can explain the underlying process, not just the issue.
- 2
Do the applied exercises thoughtfully
The footprint assessments and surveys generate the data your written assignments analyze. Treating them as quick clicks starves the analysis; honest detail makes the write-ups easy.
- 3
Flashcard the ecology vocabulary
The terminology (biomes, trophic levels, cycles) is the course's main memorization load. A small daily deck keeps the science vocabulary from piling up across topics.
- 4
Reason scientifically in discussions
The DQs reward claims tied to course concepts and evidence over environmental sentiment. Cite the process or data behind your position and the rubric points follow.

FAQ
Is BIO-220 hard?
It's one of GCU's more approachable science options, with no lab-practical memorization load. The vocabulary and process questions are the substance; treat it as a science course rather than a current-events course and it's very manageable.
Does BIO-220 satisfy the science requirement?
It commonly fills a general-education science slot for non-science majors at GCU. Confirm against your degree plan, especially if your program specifies a lab science.
What assignments are in BIO-220?
Weekly discussions, written assignments, and applied exercises like ecological-footprint assessments and environmental surveys that feed into the write-ups. The rubrics reward scientific reasoning tied to course concepts.
More GCU courses
BIO-201: Anatomy and Physiology I
BIO-201 is the first half of GCU's anatomy and physiology sequence, covering cells and tissues plus the integumentary, skeletal, muscular, and nervous systems, with a lab component. It's a cornerstone prerequisite for GCU's nursing and health-science pathways, and the grade matters for competitive program admission.
BIO-202: Anatomy and Physiology II
BIO-202 completes the A&P sequence: endocrine, cardiovascular, lymphatic, respiratory, digestive, urinary, and reproductive systems, with lab work continuing throughout. Like BIO-201, it's a heavily weighted prerequisite for GCU's nursing and health-science programs.
