Earth shape and external features	Identify the major land form, feature, or geologic event; write one fact about each site.  Use this worksheet to submit your answers.   #1  #2  #3  #4  #5  #6  #7  #8  #9 What shape is the Earth (when viewed from space?) 5.8.(4)D
Internal structure	What materials make up the Earth?  How is the internal Earth organized?  Describe the layered structure; name the layers. What phase of matter is each layer made of? What familiar objects approximate or simulate the Earth's internal structure?
Forces of change	What are the forces that act to change the shape of rocks? Answer questions found here. View this power point for assistance.  Use this observation sheet for a lab activity demonstrating the way chemical weathering occurs.  You may wish to view examples of weathering here. Simulate the way forces change "rock" by conducting this lab:  Edible Tectonics. What processes change the "look" of the Earth's features? 5.8.(4)C.2, 9.1.(4)A.1-3 5.3.(4) D, 5.8.(4) C.1, 2
Pangaea and Moving Plates	Demonstrate the way conveyor belts (like those on a treadmill) move.  Could the Earth's plates be moved by a system similar to a conveyor belt?  How do fossils give evidence of Pangaea?  Where is the Mid Ocean Ridge?  What happens at the Mid Ocean Ridge?? Name the types of plate boundaries.  How do forces act to move plates?  What is convection?
Earthquakes & Volcanoes	Use the data you find here. Obtain your "Masters of Disasters" degree. Discover earthquakes that have occurred on this day in history. Plot the location of daily earthquakes and volcanoes on your world map.  Here is a list of those > 4 on the Richter scale that have occurred in the last 30 days. Compare volcanoes (dormant, extinct, and active). Maps. Student seismology. Identify a pattern. 5.8.(4)D, 5.3.(4)D,  5.8.(4) C.1, 2
Soil	Is soil important? Investigate here. Can you "Dig It?"  Watch these videos:  Importance of Soil, Chef's Challenge, Minerals in soil - work through this interactive Earth's Skin Underneath it all! Where in the world?  (Game) The Big Picture State Soils The Dirt on Soil
Minerals, Rocks and the Rock Cycle	Mineral properties Classification of Rocks Try metamorphic breakfast, metamorphism at home, or metamorphic munchies. Watch this animation. Sedimentary Sandwich. Chocolate lava!  How do three types of rock relate and change?  View and color this chart.
"Rock" Scientists	Investigate:  Alfred Lothar Wegener, Abraham Ortelius,  Harry H. Hess, Andrija Mohorovicic, Giuseppe Mercalli, Charles Francis Richter, Robert Mallet, Thomas A. Jaggar, Diana Wall, Frederick Vine, Scott Rowland, and Charles Langmuir. <>How has each person contributed to our knowledge of the dynamic Earth (5.2.(4)A.1, 5.2.(4) B.1, 9.1.(4) A.1-3)
