Wegener's Puzzling Evidence Exercise (6th Grade) Although Alfred Wegener was not the first to suggest that continents have moved about the Earth, his presentation of carefully compiled evidence for continental drift inspired decades of scientific debate. Wegener's evidence, in concert with compelling evidence provided by post World War II technology, eventually led to universal acceptance of the theory of Plate Tectonics in the scientific community. The following files are needed for this exercise and can be downloaded in pdf format (Teacher Overview, (For Teachers) Wegener's Key to Continental Positions for grade 6, Student Puzzle Pieces, Key to Wegener's Evidence sheet, and Student Map of the World Today). If students need additional hints beyond those provided below, there is a Puzzle Outline Hint to be used as a base for the puzzle. Objectives Students will observe and analyze scientific evidence used by Wegener.
Geologic Time 1. The Earth has a long, unique history. The Earth and the life it supports have changed throughout its history. Geology in the Parks Weathering involves two processes that often work in concert to decompose rocks. Both processes occur in place. No movement is involved in weathering. Geologic time scale Online exhibits Geologic time scale Take a journey back through the history of the Earth — jump to a specific time period using the time scale below and examine ancient life, climates, and geography. You might wish to start in the Cenozoic Era (65.5 million years ago to the present) and work back through time, or start with Hadean time (4.6 to 4 billion years ago)* and journey forward to the present day — it's your choice. [Note: "mya" means "millions of years ago"] Ways to begin your exploration:
Now_and_Then When you first find a fossil it is sometimes hard to tell what kind of animal it belonged to. It is usually just a part of the original animal. In this section you will find pictures of various fossils that you too may some day discover. Just click on the picture and not only will you see a larger photo of the fossil but you will also see what the original animal may have looked like millions of years ago!! Classroom Resources In this three-part lesson, students learn about natural selection, the mechanism that drives evolution. They begin by discussing the evolution of the eye and how even a complex organ can evolve through natural selection. Then they divide into groups to learn about genetic variation, adaptation, and sexual selection and report their findings back to the class.

Education World compiled some great videos that will get kids excited about the topic. For each one, we include a description and grade level. We also note the video’s capacity for engagement (“cool factor”). The Geology and Formation of the Western Land of U.S. Source: World-earthquakes.com.
