Scientists help us understand the natural world using observation and experimentation. They study everything from planets and asteroids to coral reefs in the ocean. Becoming a scientist involves going to college and learning more about one part of the natural world. For example, microbiologists focus on studying tiny things like bacteria and astronomers study the universe.
To better understand how to be a scientist…

Marine Biology: Studying Life in the Ocean
Biology is the study of living things, and marine biology is the study of living things in the ocean. That includes studying sharks, coral reefs, plankton, and more. Some marine biologists study just one animal and others study an entire ecosystem to understand how everything interacts.
Candice, pictured here, studies an invasive seagrass in the Caribbean, she wants to understand how this seagrass which is originally from the Indian ocean, will change the ecosystem. Since seagrass is at the bottom of the food chain, it gets energy from the sun and then many animals depend on seagrass for food, like turtles.
Changing the seagrass in an area could change the balance of the ecosystem in a major way. Candice studies these changes to make sure the environment is protected.
