Antarctica is a frozen land, so cold and icy that no trees can grow there. Yet scientists have discovered fossils (remains preserved in rock) of ancient trees in Antarctica. What do you think this means? I think that it means Antarctica was once not so cold as it is now and that there were trees there 2. The Himalayas in central Asia are the tallest mountains in the world. But fossils of seashells can be found high in these mountains, far from any ocean. How do you think they got there? The sea level could have been much higher than it is now Gizmo Warm-up 1. The Gizmo allows you to drag and rotate all the major landmasses on Earth. • To drag a landmass, grab it in the middle. • To rotate a landmass, grab it near the edge. • Learn the names by opening the Tools menu and dragging the Help icon over the landmasses. • Mark where you live. Open the Tools menu and drag an arrow to your location. 2. Test your geography skills. Drag and rotate landmasses randomly until you make a big mess. Then try to move them back to their original positions. When you have made the best map you can, open the Tools menu, select Screen shot, and copy the image into a blank document. Label the image “Map 1.” 3. Click Reset. Compare your map to the real one. How well did you do? I had them close together to each other and centered in the middle of the map Activity A: Solving the puzzle Get the Gizmo ready: • If necessary, click Reset. • Check that the Evidence shown is None. Introduction: In 1915, a German scientist named Alfred Wegener (VAY-guh-ner) proposed the theory of continental drift. According to this theory, the landmasses once were joined into a supercontinent called Pangaea. The landmasses then slowly drifted to their current positions. Question: What did Pangaea look like? 1. Observe: Drag South America close to Africa. Look at their coastlines. What do you notice? If you turn South America a little the coastlines match up 2. Explore: Try to fit all the landmasses together like a puzzle. • As much as possible, avoid overlapping landmasses. • When you are satisfied, take a screenshot and paste it into your document. Label this map “Map 2: Fit of the continents.” 3. Analyze: Look at your map of Pangaea. A. How well do the continents fit together? They fit good B. Is it a perfect fit? Explain. Not really, even though they do match up they don’t fit perfectly because the coastline look worn down C. Think about how the landmasses got from where they were to where they are today. Does it seem realistic that the landmasses could have moved like this? Explain. Yes because the land masses are close to where they would have been when it was just Pangea 4. Compare: If possible, present your map of Pangaea to your classmates and teacher. Look at other maps, and talk about each one. A. Are the maps very similar or very different? My map is different B. If Alfred Wegener showed you a map like this but did not have any other evidence, would you have believed his theory that the continents had moved? Explain. Probably not because without evidence he would have no way to convince me that its true ........................................................................................continued..............................................................................................
