Online Science Courses for Credit
Several schools offer free online science classes, such as OpenCourseWare programs that generally do not require students to register to gain access to course materials - but they also do not award college credit for completion. Study.com offers an affordable alternative to students who'd like to work their way toward real academic credit via online science courses covering microbiology, anatomy and physiology, basic genetics and more. Some of the courses offered include:
- Science 101: Intro to Natural Sciences - Lessons cover an array of subjects, including human anatomy, basic mechanics, ecology and thermodynamics.
- Biology 102: Basic Genetics - Instructors discuss RNA and DNA replication, gene transmission and causes of genetic mutation. They also introduce topics of concern in human genetics research and comparative genomics.
- Chemistry 101: General Chemistry - Lessons introduce students to the periodic table, atomic structure, chemical bonds, stoichiometry and nuclear chemistry.
- Geology 101: Physical Geology - Forces shaping the Earth's surface and its features are covered alongside rock types, soil structure and atmospheric science.
- Environmental Science 101: Environment and Humanity - Lessons explain the interactions occurring among an ecosystem's organisms and the environmental impact of humans' resource consumption.

Free Online Non-Credited Science Courses
African Virtual University
This international university offers several online courses in English for students from around the world.
- Inorganic Chemistry includes QuickTime videos and PDFs of lecture notes to teach students about the configuration of elements and the periodic table of elements.
Massachusetts Institute of Technology
The OCW initiative at MIT includes dozens of undergraduate and graduate-level courses related to science. Many of the courses include lecture notes, assignments, exams and video clips.
- Organic Chemistry I allows learners to study information about the structure of organic molecules, in addition to organic chemistry vocabulary. Students learn how to write transformations and how to draw structural representations and aromatic compounds. The course includes exams and their solutions for students to look over if they wish.
- The Rise of Modern Science studies the history of science while examining philosophy, social structure, magic and folk knowledge. The course includes readings from Aristotle, Einstein, Darwin and Freud. Students must purchase the majority of these works, but some readings are available for free download. Lecture notes and information on the class assignments are available on the course website.
Tufts University also offers multiple OCW courses related to the sciences. Students have access to an image gallery and PDF files while enrolled.
- Agricultural Science and Policy I focuses on natural resource conservation, policy analysis, ecological agriculture and livestock production. Students can also complete assignments if they desire.
- Histology: Study of Cells, Tissues and Organs allows students to look at the microscopic study of cells, in addition to various body systems.
- Mineralogy includes PDF files of lecture notes for students to use as they learn about atom arrangements and how to identify different minerals. The course also includes a list of links to websites related to mineralogy.
University of Massachusetts at Boston
UMass Boston offers OCW courses in several areas of the sciences, including biology, chemistry, and the environmental, ocean and earth sciences. Online materials vary by course.
- General Biology I class provides access to pre-lab assignments, tests and lecture handouts. This course includes an overview of various life processes.
- Introductory Oceanography teaches students about the history and the geographical context of oceans. Students learn about continental shelves, slope types, marine ice and types of tides. Lecture notes, images and a final exam are provided online.
