Name:_____________________________________________________________ Date:___________________________ Block:___________________ Rubric for A HISTORIC LOOK AT SEAFLOOR SPREADING: Discovery Education Board Builder (2014) Project Goal: By the end of the seafloor spreading research project you will create a digital poster using Discovery Education’s Board Builder, incorporating purposeful, appropriate, and varied media to demonstrate an understanding of the key concepts of Plate Tectonics and Seafloor Spreading. 5 (100%) Student response includes a complete, thorough and correct explanation of the required content. 5 5 5 5 4.5 (90%) Student response includes a complete and correct explanation of the required content. 4 (80%) Student response includes a correct explanation of the required content that may be lacking in detail. 3.5 (70%) Student response includes a partially complete, but correct explanation of the required content. May be missing some required content. 3 (60%) Student attempts a response to the required content; explanation is lacking evidence of understanding. Plate Tectonics: summarize the Theory of Plate Tectonics and select appropriate media on Discoveryeducation.com to accompany that summary. Describe the Theory of Plate Tectonics. Include this info: What is the lithosphere? What are tectonic plates? Identify the types of plate boundaries and how the plates move at these boundaries. Seafloor spreading: summarize how Seafloor Spreading creates new crust and select appropriate media on Discoveryeducation.com to accompany that summary. Where does seafloor spreading occur (at what type of plate boundary?) How is new crust made? How do scientists study seafloor spreading? History of Ocean Drilling Program: summarize how international ocean drilling programs have evolved and how samples collected have proven the seafloor is spreading. Include a photo of the ships involved in these ocean drilling programs. What is a core? How are core samples used to provide evidence for seafloor spreading. What was the name of initial (the first) ocean drilling program? What was the name of the ship that first recovered evidence for seafloor spreading in 1968? What was the name of the second ship and the second ocean drilling program? What years did this program last? What is the program called today and what ships are currently exploring our oceans? 1968 Glomar Challenger: Summarize how the data collected in the 1968 Glomar Challenger expedition supported seafloor spreading. Summarize where the data was collected- what ocean, name of plate boundary, what type of boundary it is. Describe what data was collected (sediment core samples- which told us the age of the sediment above the basement rock and sediment thickness) Include examples from the data collected in your paragraph. (Think about the sites closest to and furthest from the ridge.) From the data collected, what was the average rate of seafloor spreading at the Mid-Atlantic Ridge? 5 1996 JOIDES Resolution: Summarize how the data collected in the 1996 JOIDES Resolution expedition supported seafloor spreading. Summarize where the data was collected- what ocean, name of plate boundary, what lithospheric plates are on either side, what type of boundary it is. Describe what data was collected (sediment core samples- which measured sediment thickness & sonar which measured distance to the ocean floor) Describe how the data collected support the theory of seafloor spreading. 5 Graphs: Construct a graph to represent the data collected from each of the expeditions studied. Insert these graphs on your board to accompany the expedition summaries. Label X- and y- axes correctly Title Graph Data plotted correctly 30 Name:_____________________________________________________________ Date:___________________________ Block:___________________ Rubric for A HISTORIC LOOK AT SEAFLOOR SPREADING: Discovery Education Board Builder (2014)
