Home › Courses › Environmental Science vs Biology 1
Both are science lecture courses with ACE and NCCRS credit recommendations; whether one meets your science requirement is your college's decision. NCCRS recommends 3 semester hours for each, but ACE recommends 1 for Environmental Science and 3 for Intro to Biology 1. If your college goes by ACE, Biology 1 carries the larger recommendation.

From the syllabi: what only one course covers, and where they meet.
| Environmental Science | Biology 1 | |
|---|---|---|
| Chapters | 14 chapters | 15 chapters |
| Instructional hours | 44 hours | 66 hours |
| ACE recommends | 1 semester hour (UPIS-0025) | 3 semester hours (UPIS-0009) |
| NCCRS recommends | 3 semester hours each | |
| NCCRS subject | Introduction to Environmental Science | Biology I and II, Ecology, Natural or Integrated Science |
| Final exam | 100 multiple-choice questions | 118 multiple-choice questions |
| Prerequisites | None listed in either syllabus | |
| Lab | No lab: both are lecture courses | |
Both are self-paced: quizzes and the assignment are open-book, the final is proctored, and 70 or higher passes. ACE's subject is Introduction to Environmental Science for one and Introduction to Biology for Nonmajors for the other.
Both are non-lab science courses. Ask which requirement each meets.


It is a science lecture course: NCCRS recommends 3 semester hours in Introduction to Environmental Science, and ACE recommends 1 semester hour (ACE ID UPIS-0025). Whether it meets your science requirement is your college's decision. It has no lab, so it will not meet a lab requirement on its own.
Because ACE and NCCRS recommend different amounts for it: ACE recommends 1 semester hour and NCCRS recommends 3. Intro to Biology 1 has 3 from both. Ask your college which recommendation it uses.
Not here: Environmental Science and Intro to Biology 1 are both lecture courses with no lab. If your program needs a lab science, see lab vs non-lab science credit; our lab courses are in chemistry, physics, and anatomy and physiology.
Environmental Science (ENV 121) covers ecosystems, biodiversity, environmental health, water, food and farming, air and climate, energy, waste and sustainable cities. Intro to Biology 1 (Biology 100) covers the chemistry of life, cells and membranes, metabolism, respiration and photosynthesis, genetics, gene expression and evolution.
Environmental Science: NCCRS recommends 3 semester hours, lower division, in Introduction to Environmental Science among other subjects; ACE recommends 1 (ACE ID UPIS-0025). Intro to Biology 1: NCCRS recommends 3 semester hours, lower division, in Biology I and II among other subjects; ACE recommends 3 (ACE ID UPIS-0009).
Intro to Biology 1 is longer by its syllabus. Environmental Science: 14 chapters and 44 instructional hours. Intro to Biology 1: 15 chapters and 66 instructional hours. Both are self-paced, so you finish as fast or as slow as you want.
No prerequisites are listed for Environmental Science and Intro to Biology 1, so the order is up to you and your program.
Environmental Science: 100 multiple-choice questions, 50% of the grade. Intro to Biology 1: 118 multiple-choice questions, 50% of the grade.
The same way: quizzes 20%, the assignment 30%, the final exam 50%. A pass is 70 or more.

Environmental Science: yes, ACE ID UPIS-0025, 1 semester hour. Intro to Biology 1: yes, ACE ID UPIS-0009, 3 semester hours. ACE listings run three years and UPI Study renews them as they end; credit you have earned stays valid for 10 years.
Intro to Biology 2. In the “General biology” order on the Science and labs courses page, it follows Intro to Biology 1. Your program may set its own order.
70 or more passes Environmental Science. Your transcript's grading scale shows the letter grade 70 maps to, which most colleges read as a C.
Yes: every UPI Study course is its own enrollment, so you can take Environmental Science without any other course and transfer it by itself.
ACE and NCCRS have over 2,100 cooperating colleges that will consider accepting credits; the final decision is with the universities. Search your school in Find My College and ask your registrar which requirement each one would meet. It helps to name the subject: NCCRS recommends Environmental Science in Introduction to Environmental Science and Intro to Biology 1 in Biology I and II.
