Introduction

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.  

 



The Task


1.    First you need to know the basics of glacial formation and movement.  You are to write a 1 page (double-spaced, 12 point font) descriptive summary of how a glacier forms and moves.  Diagrams with explanations are suggested to be used here, but will not account for the page of text.

 
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




The Process

  1. First you'll be assigned to a team of 2 students. You will be assessed on how well your final product is as a team.  It is your individual duty to be sure that your partner as well as yourself are on task.
  2. In order to accomplish the first task you are going to need to access the following three websites and fins information to answer the question assigned in task one.  You must apply information from all three sites in your summary (remember to use your own words, plagiarism is a crime).

(Hint- Check the General Info - Q&A section of the above site)

Icefields and Glaciers


   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.***
 




   7. 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.

Conclusion

    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.
