Presentation Transcript

  1. 5 minute check September 30, 2013 Do you know what the Nebula Theory is? Video 3.1 - The student will describe the characteristics of the layers of the earth.

  2. Collect from Friday • Bubble Lab Sheet • Penny Lab Sheet • Go over Quiz from Friday • Look at grades on back wall

  3. Today’s Vocabulary • Geology-The study of Earth processes and materials • Materials are rocks ex. Basalt, Granite, Iron and Nickle

  4. Introduction to Earth’s Layers • http://www.iteachbio.com/Earth_Science/Earth_Science/IntroEarthSurface.mov

  5. Closing: • Why do we need to take time to select the correct bar graph, why can't we use any one?

  6. 5 minute check October 1, 2013 How did our solar system form? 3.1 - The student will describe the characteristics of the layers of the earth.

  7. Today’s Vocabulary • Geology-The study of Earth processes and materials • Materials are rocks ex. Basalt, Granite, Iron and Nickle

  8. Students will build their Earth’s layer’s foldable

  9. Closing • Describe one layer of the Earth?

  10. 5 minute check October 2, 2013 Name 2 layers of the Earth? 3.1 - The student will describe the characteristics of the layers of the earth.

  11. Today’s Vocabulary • Geology-The study of Earth processes and materials • Materials are rocks ex. Basalt, Granite, Iron and Nickel

  12. Collect from Friday • Bubble Lab Sheet • Penny Lab Sheet

  13. Earth, Inside & Out • The Earth is divided into three layers • Crust • Mantle • Core Baker 7th grade science 2003-2004

  14. Today we are going to learn about the center or core of the planet • http://www.iteachbio.com/Earth_Science/Earth_Science/The%20Core-.mov

  15. Core • i)       Deep within the Earth is the core • ii)    The core is made mostly of nickel & iron • iii)  Twice as dense as the mantle. • Main source of heat that triggers the convection currents Baker 7th grade science 2003-2004

  16. The core is made of two layers • (1)  Outer core:Liquid & is responsible for the Earth’s magnetic field. • Inner core: solid Baker 7th grade science 2003-2004

  17. Today we are going to learn another layer of the planet the Mantle • http://www.iteachbio.com/Earth_Science/Earth_Science/The%20Mantle-.mov

  18. Mantle • (1)  Hotter and denser than the crust because the deeper you go inside the earth, the temperature & pressure increases. • (2) Made of solid rock. • The Mantle is made of two zones Baker 7th grade science 2003-2004

  19. Mantle Zones • (a)  Lithosphere • (i)    Thin, uppermost part of the mantle; cooler & less rigid • (ii) Floats on the athenosphere, and slides around very slowly. • (iii)  The upper part of the lithosphere melts rocks, forming a substance called magma. Baker 7th grade science 2003-2004

  20. Magma • 1.  Magma (melted rock) moves like hot oatmeal. • Uneven heating causes material in the mantle to constantly and slowly rise & fall in convection currents. • Convection Current: process by which hot fluid rises to the surface, and then sinks again, like soup being heated in a saucepan Baker 7th grade science 2003-2004

  21. (a)  Asthenosphere • Hot, weak zone directly under the lithosphere • Flows at a very slow rate Baker 7th grade science 2003-2004

  22. Today we are going to learn about the last layer of the Earth, the Crust • http://www.iteachbio.com/Earth_Science/Earth_Science/The%20Crust-.mov

  23. Crust • (1)  This is the outermost layer of the Earth. • (2) This is the layer we walk on. • (3) It is a thick, rocky skin. • (4) If we think of the Earth as a billiard ball, this crust is as thin as a postage stamp stuck on a billiard ball. • (5) At its thickest, which is under mountain ranges, the crust is only about 35km (22mi) thick. Baker 7th grade science 2003-2004

  24. And what type of crust would you like with your Earth? • There are two types of crust Baker 7th grade science 2003-2004

  25. Continental Crust: • 1. Makes up the continents • 2. Contains light colored rocks such as granite. • 3. Floats high on the mantle Baker 7th grade science 2003-2004

  26. Oceanic Crust • 1.       Makes up the ocean floor • 2.     Contains the dense rocks such as basalt • Thinner than the continental crust Baker 7th grade science 2003-2004

  27. Closing: • What is something we learned about the core of the Earth?

  28. 5 minute check October 3, 2013 What is something we learned about the core of the Earth? 3.1- The student will describe the characteristics of the layers of the earth.

  29. Students will work today on What’s inside the Earth packet?

  30. Closing: • How is the mantle different from the core?

  31. 5 minute check October 4, 2013 How is the mantle different from the core? Video 3.1 - The student will describe the characteristics of the layers of the earth.

  32. Students will take weekly quiz on layers of the Earth

  33. Glue lyrics in notebook Listen to song-http://www.flocabulary.com/geology/

  34. Closing: • What are the three layers of the Earth?
