  1. Journey to the Center of Earth By Kelly Kupferschmid EDU 553 1/15/02

  2. Layers of the Earth • Outer Crust • Inner Crust • Mantle • Outer Core • Inner Core

  3. Outer Crust • This is the layer that we live on • The thickness ranges from five miles under the oceans to 25 miles under the continents • Consists of cooled rock • It is the thinnest layer of the earth

  4. The Mantle • This layer is semi- liquid • It consists of magnesium, iron, and silicon • It is 3000 km wide • It is more solid closer to the surface

  5. The Outer Core • This is consists of liquid due to the high temperatures • It is 2100 km wide • This layer consists of nickel and iron

  6. The Inner Core • This layer is solid. • The reason it is solid is due to the high pressure exerted on it from the outside layers. • It consists of the metals nickel and iron. • Its temperature is 6,000 degree Celsius. • Its width is 2,100 km.

  7. Activity # 1- Making a Cross Section • Identify the layers of the earth (crust, mantle, outer core, and inner core). • Look at an apple • Identify the skin (crust) • Identify the apple (mantle) • Identify the outside of the seeds (outer core). • Identify the inside of the seeds (inner core).

  8. Activity #2- Making Flash Cards • Listen to the book “Magic School Bus- Inside the Earth.” • Make a list of the earth’s characteristics. • Get into groups of four. • Make flash cards using the information form the book. • Quiz each other and see who gets the most correct.

  9. Activity #3- Making a Model of the Earth • Review the characteristics of the layers of the earth. • Choose four facts that you wish to discuss. • Make a poster of the earth, its layers, and the information that you chose.

  10. Assessment • Have students present his/her poster or earth creation. • Grade them on the responses to the flashcards. • Play a game that involves questions about the crust, mantle, outer core, and inner core.
