Science degrees, especially in fields like marine biology and environmental science, often seem daunting for students without prior knowledge in science during their K12 years. However, the journey from having no scientific foundation to successfully pursuing these majors is not as impossible as it may appear.

The Nature of Science Learning
Science learning is not just about memorizing facts. It involves understanding concepts, developing critical thinking, and learning how to conduct research. For instance, in marine biology, students need to understand the complex ecosystems of the ocean. According to Marine Biology on Wikipedia, it encompasses various aspects such as the study of marine organisms and their interactions. Similarly, environmental science, as defined on Environmental Science on Britannica, requires an understanding of the environment and how human activities impact it. These fields are more about building knowledge step by step rather than relying solely on prior learning.
Preparing for the Journey
- Self-Study: Start by learning basic scientific concepts. There are numerous online resources available for free. For example, platforms like Coursera offer introductory courses in biology and environmental science.
- Build a Strong Foundation: Focus on fundamental subjects such as biology, chemistry, and physics. Understanding these basics will make it easier to grasp more advanced topics in marine biology and environmental science.
- Get Practical Experience: Try to get involved in volunteer projects related to the environment or marine life. This hands-on experience will give you a better understanding of the field.

Real-life success stories also prove that lack of prior knowledge is not a barrier. For example, some students with a humanities background have successfully switched to marine biology or environmental science majors. They worked hard, caught up on the basics, and developed a passion for the subjects. With the right approach and dedication, anyone can embark on this scientific journey.
Readability guidance: As seen above, we’ve used short paragraphs and lists to summarize key points. Each H2 has a list to make information clear. We’ve also kept the passive voice and long sentence ratios in check and added transition words like ‘however’, ‘for instance’, etc., throughout the text.
