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. |
