INTRODUCTION TO EARTH SCIENCE
ESCI 121
Fall 2010
Section 05

DAILY OBJECTIVES
By the end of today's class, you should be able to do the following:

w
List the names of three major layers of Earth's internal structure based on the two responses to stress.  For each layer, describe the conditions that characterize that layer, and tell roughly how thick it is in comparison to the others.

w Participate in a Jigsaw exercise to investigate Earth's large scale patterns:
 
EXPERT GROUPS
 
  ▫ Break into Expert Groups, based on what you studied for the homework assignment:
  Group 1:  Volcanoes
Group 2:  Hotspot volcanoes
Group 3:  Earthquakes
Group 4:  Focal depth of earthquakes
Group 5:  Thickness of Earth's crust

▫ Record the names of your colleagues in your Expert Group.

▫ Examine the maps that each person in your Expert Group brought today for their homework assignment.  Does each map show exactly the same thing?  Compare maps; note any similarities and differences.

▫ Using your world map from last class, the ocean floor map, and the world map, locate and plot on the Expert Group maps our 14 study sites from last class.

▫ For each study site, determine the characteristics of that site based on your group's area of expertise. (For example, if your group's area of expertise is "Hot spot volcanoes", then for each site, tell whether hot spot volcanoes occur at that location, or not.) 

▫ Record your observations for each site on the Expert Group Summary Sheet provided.  Before you leave this group, everyone in the group should have a complete set of all the same information.

JIGSAW GROUPS

▫  Break into Jigsaw Groups, one Expert "puzzle piece" in each Jigsaw Group.

▫  Record the names of the others in your Jigsaw Group.


Compiling the Data


▫  In your Jigsaw Group, examine each of the 14 study sites. For each site, each Expert should call out what they know about that site, and everyone should record it on their own Jigsaw Group Summary Sheet.

Analyzing the Data

You have just participated in a very large data-gathering effort. Now comes the fun part: scientifically analyzing the data!

▫  Study the data and pick out patterns.  Include the topographic and geographic data you recorded last time.  (Usually patterns will take a form something like this: "In all locations where X is true, Y is also true.")   Write a short description of the pattern, supporting your statements by citing the data, giving examples to support your arguments, and noting any exceptions to general trends.
 
  Teams can earn one point for each valid and supportable pattern they discern, up to a maximum of four points.

Peer Review Other Scientists' Work

Finally, each team will peer review another team's list of patterns.  For each pattern, decide if your team agrees that the pattern exists and is supported by the data.  Write a review and back it up by citing specific data or examples. 

  As Peer Reviewers, teams can earn one half-point for each pattern they review correctly, up to a maximum of two points. 

Total possible for today's work: six points.
