Name: ___________________________________ Period: ________ Date: ____________________ Letter to Wegener Scientists! When Alfred Wegener first suggested the idea that the continents move, many other scientists thought he was CRAZY! But we, as modern scientists, know he was not crazy, but he was right. It will be our task to write letters to Wegener, explaining to him how the Theory of Plate Tectonics explains not only that the continents are in different positions today than they were long ago, but also HOW they move. Today, scientists have more evidence than Wegener had, and they can support with solid evidence ideas that Wegener could only begin to imagine. Thank You for believing in me!! In order to truly make Mr. Wegener understand, your letter should make a strong scientific argument. In order to do this, you need to include the following things: Have an opening paragraph that makes a claim. You should tell Mr. Wegener that he was correct in believing the continents moved. You should also explain why you’re making that claim. Briefly discuss how the Theory of Plate Tectonics explains not only how the plates move, but also explains other features of Earth’s surface, including (but not limited to) mountains, earthquakes, and volcanoes. Remind Wegener of at least three pieces of evidence he had when he was alive that supported his theory of continental drift. Present several pieces of MODERN evidence to Wegener (that you have found in our research) that supports the Theory of Plate Tectonics. Focus on modern evidence! This evidence should explain why the playes move, and must also explain certain features of Earth’s surface (i.e. volcanoes, mountains, earthquakes, etc.) You must explain why each piece of evidence supports the Theory of Plate Tectonics. You must explain how the tectonic plates move!! Use the following vocabulary words: The Theory of Plate Tectonics, divergent, midAtlantic ridge, convergent, mountain, subduction, volcano, transform, slide, convection currents, GPS data, Each piece of modern evidence should be explained in its own paragraph. You will first state what the modern evidence is and then explain the reason that this evidence supports Wegener’s belief that the continents moved. You must also discuss what else this evidence tells us about the Earth’s surface. Use the term “Theory of Plate tectonics” several times in this letter! You might also outline how this theory explains landforms and events such as volcanoes, mountains, earthquakes, and eruptions. A concluding paragraph that summarizes what you know about the Theory of Plate tectonics, congratulates Mr. Wegener, and explains, once again, why he was correct! In order to fully explain your ideas, each paragraph should be at least five sentences long. On the back of this sheet is a grading rubric that lets you know how your letter will be graded. In order to get an outstanding grade on this assignment, be sure that your letter follows all of the steps listed above, is easy to understand, and is convincing. Letter Grading Rubric 4 (Above the standards) 3 (Meets standards) 2 (Developing to meet standards) 1 (Does not meet standards) Gives more than 3 pieces of modern evidence that supports the Theory of Plate Tectonics. Reminds Wegener of at least three pieces of his evidence and explains them. Letter states and thoroughly justifies the claim that the continents/plates move though analyzing the evidence. Letter thoroughly explains HOW the tectonic plates move. A clear reason is given for why each piece of evidence supports the theory of Theory of Plate Tectonics. These reasons are logical and easy to understand. Letter has a convincing conclusion that restates to Mr. Wegener why he was correct in believing the continents move. The letter is neatly written and each paragraph has five or more sentences. ALL 11 vocabulary words are used correctly Gives exactly 3 pieces of modern evidence that supports the Theory of Plate Tectonics. Reminds Wegener of at least two pieces of his evidence and explains them. Letter states and mostly justifies the claim that continents/plates move through some analyzation of the evidence. Letter mostly explains HOW the tectonic plates move. A reason is given for why each piece of evidence supports the theory of Theory of Plate Tectonics. These reasons are usually logical and mostly easy to understand. Letter has a conclusion that restates to Mr. Wegener that he was correct in believing the continents move. Each paragraph has five sentences and the letter is neatly written. ALL 11 vocabulary words are used, but three or less were not used correctly Gives 2 pieces of modern evidence that support the Theory of Plate Tectonics. Reminds Wegener of at least three pieces of his evidence but does not fully explain them. Reminds Wegener of at least three pieces of his evidence. Letter states the claim that continents/plates move, but does not clearly justify this claim or analyze the evidence. Letter discusses HOW plates move, but doesn’t fully explain. A reason is given for each piece of evidence, but the reasons do not make a lot of sense. Letter has a conclusion. Some paragraphs have less than five sentences and the letter is somewhat messy and not professional looking. Missing some vocabulary words, or more than 4 were used incorrectly Gives one or no pieces of modern evidence that supports the Theory of Plate Tectonics. Reminds Wegener of two or less pieces of his evidence but does not fully explain them. Letter does not state the claim that the continents/plates move. Letter does not discuss HOW the plates move. No reasons are given to explain why each piece of evidence supports the theory of continental drift. Letter does not have a conclusion. All paragraphs are less than five sentences long and the letter is difficult to read. Missing all or most vocabulary words, or all words are used incorrectly.
