2. Warm Up… Review for MSL! 1. Which section of Earth’s interior is composed primarily of liquid metal? A crust B mantle C outer core D inner core 2. Due to extreme pressure, the inner core of Earth is A solid B liquid C gasD plasma 3. When an earthquake occurs, the speed of the seismic waves changes as they A. move through different materials. B. are pulled by the force of gravity. C. lose energy to surrounding rocks. D. reflect off of boundaries.

3. Think about this statement How can soil be lost or degraded (means has less vitamins and nutrients) over time? Do you think we can see this damage around us? Do you think we could have a better view of these changes from space? Scientists use something called Remote Sensing

4. Remote Sensing video https://www.youtube.com/watch?v= sBI3MIbzIBA https://www.youtube.com/watch?v= sBI3MIbzIBA

5. Write in notebook Remote Sensing Satellites in space used to look at the Earth’s surface Takes pictures of the Earth Shows how Earth’s surface has changed due to humans Information used to protect, preserve, and predict future changes

6. WRITE IN NOTEBOOK Soil Conservation: the management of soil to prevent its destruction

7. WRITE IN NOTEBOOK 2 Main purposes of Soil conservation: 1. Prevent and reduce erosion (hold the soil in place) 2. Maintain and improve soil fertility (vitamins and nutrients in soils)

8. WRITE IN NOTEBOOK Soil conservation techniques: Contour Plowing Conservation Tillage Terracing Crop Rotation

9. Videos on Soil Conservation What is crop rotation https://www.youtube.com/watch?v=O9YDlcKG4rA Farming the contour https://www.youtube.com/watch?v=ChEgH4Jcl5A Conservation tillage https://www.youtube.com/watch?v=qbbnerV_Pws Farming basics terraces https://www.youtube.com/watch?v=qbbnerV_Pws

10. In the remaining time…. You will use textbooks to begin researching soil conservation methods and techniques You will use your knowledge to create an informational brochure Directions and a rubric will be provided now!

11. Soil Conservation Brochure Research Turn to page A 135- 136 Description / definition for: Soil Conservation Contour Plowing Conservation Tillage Terracing Crop Rotation

12. REAL WORLD EXAMPLES CONTOUR PLOWING: In the hills of Pennsylvania CONSERVATION TILLAGE: Crops growing in California TERRACING: Rice growing in Indonesia CROP ROTATION: Corn and soybeans growing in Wisconsin

13. Brochure Activity You will be given one piece of paper for your brochure (DO NOT MESS UP!) You will be given an example brochure too Lastly, you will be given a rubric to show how these will be graded In the remaining time, you will complete your soil conservation brochure DUE TODAY IN CLASS – DO NOT WASTE TIME!
