Online Science Classes

The best online courses in science instruct students in the areas of biology, chemistry, physics, earth sciences and mathematics. Classes prepare students for the job market by teaching skills in research, record keeping, critical thinking and analysis, observation and planning and organization.

Online Science Classes

Quality online classes prepare students for careers in the rapidly growing science and technology sector as well as in the agriculture, consulting, health care, government, industry and research fields. The study of science involves a variety of courses, including biology, chemistry, physics, earth science and more. A comprehensive science education provides the necessary background for individuals wishing to teach science in primary or secondary schools.

Knowledge Gained

Students will gain foundational knowledge in many subjects, such as:


Biology coursework teaches students about living organisms at molecular, cellular and organismal levels and common life processes. Biology science classes cover a wide berth of subjects, which may include botany, zoology, human anatomy, ecology, genetics and microbiology.


Students are required to gain familiarity with the principles and practices of chemistry. Instructors teach students about the properties of gases and other common elements, makeup of solutions, chemical equations, chemical reactions, atomic structure, bonding, laboratory instruments and experimental methods.


In this course, students build a strong understanding of the laws of physics. Classes on physics may expose students to the concepts and principles of optics, electricity, magnetism, kinematics, elasticity, vibrations, waves and sound, heat, acceleration, velocity and linear, circular and rotational motion.

Earth Sciences

Students also cover earth sciences, which study the nonliving components that make up the planet, including rocks and minerals, freshwater, salt water, ice and atmospheric gases. Other subtopics studied include the planet's interior, electromagnetic field, historical weather phenomena and geological occurrences like earthquakes and volcanoes.


Students enrolled in this course acquire a working understanding of mathematics through statistical research and required math curriculum. Mathematics coursework for science students typically includes an overview of integral calculus and focuses on techniques and applications in various science fields.

Skills Developed

Students will also develop many useful skills, including:


Science students cultivate technical and scientific research skills by first learning about the scientific method. Students will learn different types of experiments, hypotheses formulation, control and experimental variables, data collection and analysis, proper instrument use and personal safety measures.

Record Keeping

Science programs with experimental or observational research projects teach students record keeping skills for tracking research subjects, time and location, variables, materials and instruments, observations, results and conclusions. These record keeping abilities translate well into careers as scientists, researchers and healthcare practitioners.
