GEOL 333 - Lab #11 Information (Soil Presentation Guidelines, Presentation Date = April 4)

Assignment

During Lab on April 4, each student or student group will give an oral presentation about one of the twelve soil orders (categories). The twelve soil orders (listed below) were assigned randomly. The presentation must be 3 - 5 minutes in length with several minutes for questions. There are twelve presentations to give in one hour and 50 minutes, and the time limit must be enforced strictly. For the presentations with two students, each student should give ~half of the presentation. All presentations of soil orders must include the following:

(a) Soil Order Characteristics - including presence and development of soil horizons, soil fertility, any other significant soil properties, and any characteristic age, vegetation and soil minerals, if applicable

(b) Environment of Formation - features of climate, bedrock composition and topography, if applicable

(c) Distibution in USA and World - Locations in USA and the world where the soil order occurs and why it occurs there. 

You must also turn in a typed outline of your presentation before you give your presentation.  The outline should include all of the key information in your oral presentation, and it should be in a similar sequence as your oral presentation. Make sure to give an effective presentation, which includes a good opening and closing as well as good organization. You should practice your presentation to ensure that you are within the time guidelines and that you deliver it effectively. Prof. Altaner will attend the presentations.

Soil Orders (and informal name)

Alfisol = deciduous forest soil
Andisol = formed on volcanic ash
Aridisol = desert soil
Entisol = alluvium soil
Gelisol = tundra soil
Histosol = organic soil
Inceptisol = young soils
Mollisol = prairie soils
Oxisol = tropical soil/laterite
Spodosol = coniferous forest soil
Ultisol = sub-tropical
Vertisol = swelling soil

Purpose

The purpose of this exercise is to introduce you to the variety of soil types based on own research and the oral presentations of fellow students. In addition, you get to practice your communication skills.
 
Grading

    25 points for Content (based on accuracy and coverage)
    5 points for Style (use of effective opening and closing statements, organization, delivery)

    Total = 30 points

Up to 5 Extra Credit points may be given based on creativity, handouts, visual aids, or other special features of the presentation.

There is excellent information about each soil order including photos and maps of their distribution in USA and the world at: <http://soils.cals.uidaho.edu/soilorders/orders.htm>.

Powerpoint Presentations

If anyone wants to give a Powerpoint slide presentation, then you must send your Powerpoint file to Haley by 5 pm on Monday, April 43 so that she can load these files onto her laptop computer, which will be used for all Powerpoint presentations. Give your Powerpoint file a name that includes your soil order and your last name, e.g., Histosol_Altaner. If you do not meet the 5 pm, April 4 deadline for sending Haley your Powerpoint file, then you cannot give a Powerpoint presentation. Students must be prepared to give their presentation even if computer projection equipment does not work.

Copies of Black and White Handouts

If you would like
black and white copies for handouts to the class or overhead transparencies, then put copy-ready printed originals into Haley’s mailbox in 144 CAB (or give them to Haley in person) by Noon on Monday, April 3.  She'll have the copies ready for your presentation in Lab. 

Schedule of Presentations - Assignments will be made randomly in Lab on March 14
