NASA calls the ocean the great unknown, because we know more about the surface of the moon than the bottom of the ocean. Marine biologists study marine life by swimming with sharks or learning about life processes by studying plants that grow with almost no sunlight, making them some of Earth's greatest adventurers. With explanations about how one becomes a marine biologist and the many different paths their careers might take, this book is perfect for readers who are adventurers, animal lovers, swimmers, or simply curious about what's under the water that covers 70 percent of Earth.

Oxygen is one of the most essential needs for life on Earth, and respiration is how living things use it. But there's a lot more going on in this seemingly simple process than you might think. The respiratory system is in some ways the most underappreciated of the body systems, since it works 24/7, mostly without being noticed, and never gets a single moment's rest. In this book, readers discover the most fascinating facts about respiration, the structure of the lungs, and even some of the seemingly gross processes that happen in their body

There is so much we still are still learning about outer space, and aerospace engineers are leading the way, helping to build the technology we use to guide the men and women who travel into the cosmos. It's a job that includes the study and use of math, physics, chemistry, biology, and even agriculture. Some aerospace engineers even decide to test their own work and become astronauts themselves. Through this book, readers learn what it takes to become part of this amazing world of STEM careers through science-curriculum supporting content and real-life photographs of scientists at work.

Has anyone ever told you to "think big?" Microbiologists do the opposite: think small, so small they can only see it with a microscope. Readers learn that though microbiologists study the smallest organisms on Earth, they ask big questions about life processes, like sickness and health, and everyday questions, such as how bread is made. Including the schooling, training, and daily tasks of these incredible scientists, the main content also covers information readers will encounter in the science classroom, such as how bacteria grow, methods for experiments, and perhaps how to bake a better loaf of bread.
