How We Learned The Earth Is Round

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.

We all know the earth is round. But HOW do we know? Join intrepid young scientist-adventurer Joulia Copernicus as she takes readers on a historical journey through time and space. From jumping on board Columbus's ship to planet-hopping in the outer reaches of our solar system, Joulia explains with humor and wit the ins and outs of how we learned that the earth is round.

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.

Is it time to refresh the way you think about teaching Earth science? Learning to Read the Earth and Sky is the multifaceted resource you need to bring authentic science—and enthusiasm—into your classroom. It offers inspiration for reaching beyond prepared curricula, engaging in discovery along with your students, and using your lessons to support the Next Generation Science Standards (NGSS). The book provides • examples of Earth science labs and activities you and your students can do as co-investigators; • insights into student expectations and misconceptions, plus ideas for inspiring true investigation; • stories of real scientific discovery translated for classroom consideration; • exploration of how you can mentor students as a teacher-scholar; and • guidance on how to translate the sweeping core ideas of the NGSS into specific examples students can touch, see, and experience. The authors of Learning to Read the Earth and Sky are husband-and-wife educators who promote science as something to figure out, not just something to know. They write, “It is our hope that readers will find our book short on ‘edu-speak,’ long on the joy of doing science, and full of stories of students, classrooms, scientists, and Earth and sky.”
