1. Spaceship Earth Investigating Earth Materials

2. The Blue Marble The title of this photograph is “The Blue Marble.” What is this blue marble? Who do you think might have taken this photograph? Why do you think they named it as they did?

3. Spaceship Earth What can you tell about Earth from this photograph? The Earth is like a spaceship on which we travel. It has everything we need to stay alive.

9. Earth’s Atmosphere The Earth’s atmosphere is constantly changing, too.

10. Earth Changes Man also changes the Earth.

11. Mission: Spaceship Earth Your mission as an Earth scientist is to learn more about these Earth materials. By studying the Earth and how it works, we can use and protect these natural resources. After all, it’s the only Earth that we have.

19. Real Scientists There are many more ways that geoscientists study the Earth. You can learn about some of the these interesting jobs from real scientists at: http://pbskids.org/dragonflytv/scientists/index.html Check out Elizabeth Arrendondo – Mineralogist “Mineralogist Elizabeth Arredondo loves adventure! When she's not skydiving, she's out hunting for colorful gems and minerals.” (PBS KIDS: Dragonfly TV)
