A WebQuest for Regents Earth Science Designed by Mr. Ertl Introduction | Task | Process | Evaluation | Conclusion | Credits | Teacher Page While hiking on the south island of New Zealand you are in awe of
the great glaciers that inhabit some of the island. Two particular glaciers
that get your attentions are Fox Glacier and Franz Josef Glacier, located
in Westland National Park on the west coast of the south island.
Based on these two inspiring natural wonders you have become quite intrigued about glaciers and your trip has sparked your desire to become more of an “expert” on glaciers and glacial features.
2. Since you now want to travel to other exotic locations and hike glaciers you need to become familiar with the “lingo” and terms associated with glaciers. Below is a list of terms that you must define. Along with the definition you are to locate a descriptive picture that you may use as a reference when studying glaciers. For some of the terms a specific description of location is also needed along with the definition. Terms – 1. Glacier 2. Valley Glacier (Alpine Glacier) 3. Continental Glacier (Ice Sheets) 4. Ice Caps 5. Crevasses 6. Iceberg 7. Zone of Accumulation 8. Zone of Ablation 9. Calving 10. Ice Front 11. Moraines medial moraine, terminal (end) moraine) 12. Rock Flour (Glacial Milk) 13. Striations 14. Cirque 15. Horn (Matterhorn) 16. Arete 17. U-Shaped Valley 18. Hanging Valley 19. Till 20. Outwash 21. Erratics 22. Drumlins 23. Outwash Plains 24. Eskers 25. Kames 26. Kettles 27. Cirque Lake 28. Kettle Lake 29. Moraine-damned lake 30. Chattermarks In order to accomplish your tasks you will be required to use a variety of selected websites that are listed below in "The Process Section". New York State Standards
Natural agents of erosion, generally driven by gravity, remove,
transport, and deposit weathered rock particles. Each agent of erosion
produces distinctive changes in the material that it transports and creates
characteristics surface features and landscapes. Glaciers (moving ice): Glacial erosional processes include the formation of U-shaped valleys, parallel scratches, and grooves in bedrock. Glacial features include moraines, drumlins, kettle lakes, finger lakes, and outwash plains. Patterns of deposition result from a loss of energy within the transporting system and are influenced by the size, shape, and density of the transported particles. Sediment deposits may be sorted or unsorted

3. Now that you have composed the
summary of how a
glacier forms and moves it is time to move on to vocabulary portion of the webquest. 4. Your task now is to define the list of terms that you saw above. Yes, 30 terms seems like a lot, and that is why you may split them up. One student may complete the first 15 terms and the other the second. It is important that you save because you must transfer all 30 terms and the summary to one final document which will be turned in for assessment. 5. If possible small pictures of the terms are highly recommended. This document will be used as a study guide for glaciers in the future. 6. In order to find your definitions and pictures you may use the sites that you used in task 1 or you may access the new sites listed below. ***Do not use the same site for every term, use a variety and be sure to read what you are typing.*** Swiss

Once you have finished both Task 1 and Task 2, be sure that both are assembled into one document, with names, date, and a title. Print one document to hand in, and if you wish you may print one other to use as a study guide. The partner without a print copy will receive the one handed in once graded. ****Also please save your final product somewhere, your teacher may want a clean copy.**** If you have time left over take a look at the following site and learn a little more about Fox Glacier and Franz Josef Glacier in New Zealand.
You and your partner will receive the same grade for your glacier project and will be awarded based in the following rubric.
Beginning 1 Developing 2 Accomplished 3 Exemplary 4 Score Now you should be an expert on glaciers. Not only do you know how glaciers form and move, but you also know some of the major features that are produced by glaciers and what they look like. The time was well worth the effort because you also have created a quality study guide that you may use for future exams. Image Sources www.keatours.co.nz/glaciers.asp
