People used to think that Earth was flat, but now we know it isn’t. How did we find out Earth is actually a sphere? How did science help us understand the shape of our planet? Readers will delight in exploring the history and science behind Earth’s spherical shape. They’ll learn how satellite images and modern technology give us an image of the Earth. Readers will also learn all about early scientists and how they gradually came to enlighten others that the Earth wasn’t flat. Clear diagrams and fascinating sidebars help explain this important science topic, as supplemental science experiments give readers the hands-on experience they need to grasp the topic.

From Babylon to Columbus and beyond, a journey across millennia and—yes—the globe exploring how we came to understand our spherical planet. The Globe tells the story of humanity’s quest to discover the form of the world: that the Earth is round and not flat. Philosophers in ancient Greece deduced the true shape of the Earth in the fourth century BCE; the Romans passed the knowledge to India, from where it spread to Baghdad and Central Asia. In early medieval Europe, Christians debated the matter, but long before the time of Columbus, the Catholic Church had accepted that Earth is a ball. However, it wasn’t until the seventeenth century that Jesuit missionaries finally convinced the Chinese that their traditional square-earth cosmology was mistaken. An accessible challenge to long-established beliefs about the history of ideas, The Globe shows how the realization that our planet is a sphere deserves to be considered the first great scientific achievement.

Would you like to learn the truth about Earth, about its shape, nature, meaning, and characteristics? Then get ready to embark in the study of one of the most restricted and controversial topics, the Flat Earth Theory. Yes, the Flat Earth is back, and it has always been around, since it has always been accepted among the upper social classes. It transpires today in the Media, Politics, Entertainment, and even in Science, it becomes more and more visible, and consequently, millions of people already research the Flat Earth Theory today. Yet this time is the other way around, with authorities ignoring the Flat Earth Theory, while enforcing only the Spherical Model of Earth, along with the Big Bang Theory, the Theory of Evolution, the Theory of Relativity, and so on. Is the Earth flat or spherical? You cannot know with certainty, just because concepts as 'theory' and 'model' signify probable truth only until proven false, and therefore it is not accurate. While Science is full of theories, models, interpretations, and speculations, but not of facts. Because as long as you have access only to debatable information, records, and theories about space beyond the lower orbit of Earth, then both the Spherical and Flat models of Earth remain simple theories too, not facts. Yet this book goes beyond researching the true shape and nature of Earth, since it manages to reveal the social actors behind the main theories defining Earth Science and Space Science today, including the strategies and intentions that these social actors have from you and from the entire world. What chance can the Flat Earth Theory have against the current official model? It depends who is behind Science and how they want the Earth to be, but most importantly, it depends on which side of the line you stand this time, because this time it is all different, since this time you seem to have a choice in these.This book creates a comprehensive model of Earth and of the entire world, studying its shape, boundaries, characteristics, and social circumstances, using reasoning and accurate facts. This research of the true shape and nature of Earth is done from all perspectives: scientific, empiric, social, cognitive, existential, and spiritual. If you want to learn the truth about Earth, this book is for you.

This book not only answers this compelling question, it explains why people once thought Earth was flat, what Earth is made of, the cause of Earths seasons, and how Earth moves around in space. With gravity, the Sun, and specially designed diagrams as tour guides, students can get comfortable with the unique features of our planet.

Explains various changes in humanity's beliefs about the shape of the earth, from the flat earth theories of the ancients to the round earth theories which were proven true by the voyages of Columbus and Magellan. Includes hands-on experiments to help children to recreate the theories.

Hands-on experiments are a great way to engage young scientists. Instead of simply reading facts, they will experience the science that is happening in front of their eyes! The simple experiments in this book, illustrated in color, will unlock the secrets of planet Earth, including why Earth has layers, how continents move, and how we know Earth is round. By the time young readers are finished with the activities in this book, they will be ready to design some of their own to enter in their next science fair.

It can be hard to imagine a time when it was generally believed that the shape of our earth was a flat plane or disk. This book exposes the bizarre and sometimes hilarious history of science, explores pseudo-scientific theories from the past, and the scientific progress made since then through use of the scientific method. Through the scientific method, anecdotes, historic facts, and the scientific theories themselves, it tells the story of why people of a particular time period believed in such things and the discoveries that led us to learn otherwise.
