* The information in this laboratory investigation was modified from
 an original version (Locating Patterns of Earthquake and Volcano 
Distribution) published by Prentice-Hall, Inc. Additional maps and 
information were obtained for education use only from National 
Geographic and USGS.

Overview
The purpose of this Inquiry-Based Activity (IBA)is to allow students to follow in the footsteps of early scientists as they put the pieces of Pangaea back together and discovered the forces that create the variety of landforms and sea-floor features of our Earth. Preparation for this activity should include a review of Alfred Wegener's theory of Continental Drift. The review material should include the rock and fossil evidence available in the early 1900s to support his ideas that an original landmass (Pangaea) broke apart into several smaller pieces and "drifted" across the earth. The following link provides background about Pangaea and Alfred Wegener's research: http://pubs.usgs.gov/publications/text/historical.html#anchor9508964

Grade Level/Discipline
This activity is designed for middle grades but can be modified for elementary or high school.

Time Frame
Pangaea Puzzle is a week-long activity designed for classes with 60 - 65 minutes of instructional time. Additional time may be needed to complete the PowerPoint presentations, depending on the computer skills of the students.

Engagement and Exploration (Student Inquiry Activity)
DAY ONE: OBSERVING to COLLECTING DATA

1. Introduce the lesson with a brainstorming session to generate responses to these questions:

a. What observations could scientists from the 19th and early 20th century make to help them determine that the earth had a single landmass (Pangaea) which has broken into several pieces throughout geologic time?

b. What types of data could they collect to support their hypotheses?

c. How could earthquake and volcano data from around the world assist scientists with theories such as Continental Drift and Plate Tectonics?

2. Assign students to a cooperative learning team with 4 or 5 students in each team.

3. Distribute a copy of the IBA materials to each student. (See Appendix A in the Student Section)

a. Review the IBA Problem and Procedures with the students and answer any questions concerning the longitude and latitude coordinates that will be used in this lab.

b. Facilitate student completion of the IBA procedures. Students unable to complete the assignment during the remainder of class should finish plotting the coordinates for homework.

Explanation (Discussing)
DAY TWO: DATA ANALYSIS to APPLICATION

1. Review the following concepts from the previous class discussion:

a. What is the worldwide pattern of earthquake and volcano distribution and how can scientists use this data to make inferences about changes in the earth throughout geologic time?

b. How have technological advances (e.g., GPS, satellite imagery) changed data collection methods for geologists?

2. Encourage team members to check each other's maps for accurate earthquake and volcano plots. Corrections should be made if needed. Display a transparency of the correct plots to assist students who may have difficulty with the corrections.

3. Display a list of the following land and sea formations in the classroom:

a. Aleutian Islands

b. Andes Mountains

c. Great African Rift Valley

d. Himalayan Mountains

e. Marianas Trench

f. Mid-Atlantic Ridge

g. San Andreas Fault

4. Provide an opportunity for teams to select one of these land/sea formations for their investigation. Selections can be awarded on a first-come basis, or other appropriate strategy for the variety of choices. Teams should not duplicate selections.

5. Display the Lab Rubric in the classroom and distribute one copy to each team. (See Appendix B and C in the Evaluation Section) Review the contents and expectations of the rubric with the students and provide clarification as needed.

6. Students may work independently or in teams to complete the Lab Rubric. Facilitate student/team completion by coaching each team through the investigation of their selected land/sea formation. 7. Students should have the following assignments completed at the end of the lesson (Homework is assigned accordingly):

a. Land/Sea Formation selection

b. Hypothesis through the Procedures of the Lab Rubric

c. An outline of the research methods each team member completed for DAY TWO (using the Internet resources noted)

d. An outline of the research methods each team member needs to complete for DAY THREE.

DAY THREE: DATA ANALYSIS to CONCLUSION

1. Review the plate boundary concepts of this IBA by displaying the website:http://neic.usgs.gov/neis/plate_tectonics/majplatecolor.pdf

a. Divergent boundary

b. Convergent boundary

c. Transform or Strike-slip boundary

2. Review the Conclusion section of the Lab Rubric and provide clarification as needed.

3. Students may continue to work independently or in teams. Facilitate completion by coaching each team through the appropriate tectonic forces that created their land/sea formation. Encourage self-exploration using the Internet resources and provide open-ended prompts as needed to insure that each team is locating appropriate and accurate information.

4. Once the each team member has completed the Lab Rubric, they should construct a schematic for the Power Point presentation. This schematic should be approved by the teacher prior to any PPT computer work by the team.

5. Students should have the following assignments completed at the end of today's lesson (Homework is assigned accordingly):

a. Data Analysis through the Conclusion of the Lab Rubric

b. An outline of organized notes from the research record for their land/sea formation

c. A schematic drawing of the team's PPT presentation, including images and concepts to be covered

DAY FOUR: POWERPOINT CONSTRUCTION {COMPUTER LAB}

1. Provide each team with 2 computer stations and monitor their progress in relation to the PowerPoint Presentation Rubric to insure accurate and informative PPT presentations of their land/sea formation. Teams should have a completed a 10-minute PPT presentation or an outline for their team's Homework Assignment.

2. Teams should be encouraged to practice their presentation and monitor individual parcticipation, organization, and timing during their PPT presentation.

Elaboration (Polar Applications)
5. MAKING INFERENCES: Based on the knowledge gained in this IBA, construct a hypothesis for the formation of the Trans Antarctic Mountain Range in Antarctica. (Display a map of Antarctica, noting the location and geology of the Trans Antarctic Mountain Range. Answer questions posed by students to provide clarification pertaining to the region. Display the graphics from these websites to assist each team with their observations):

a.http://csep10.phys.utk.edu/astr161/lect/earth/tectonics.html

b.http://www.enchantedlearning.com/subjects/astronomy/planets/earth/Continents.shtml

Exchange (Students Draw Conclusions)
DAY FIVE: POWERPOINT PRESENTATIONS

1. Determine the order of presentation for the teams and provide an adequate amount of time for each team to organize their PPT files and supplemental materials (if applicable) prior to their presentation.

2. Use the PPT Rubric to record the team scores based on the objectives met during their PPT presentation. Encourage the audience to record notes about the information each team presents pertaining to their land/sea formation and determine the similarities and/or differences between the land/sea formations explored by each team.

3. At the completion of each PPT presentation, the audience is encouraged to ask questions pertaining to information that may have been omitted or presented incorrectly. Any corrections made by the presenting team during this question/answer audience session should be recorded as objectives met on the Lab Rubric. Teams with remaining errors or omissions after this Q&A session should be prompted or coached by the teacher for the information. If the information is provided by the team, a minor point deduction is recorded for each objective prompted. Teams who are unable to successfully complete the objective may lose five points to an audience member who can successfully complete the objective. (This latter strategy highly motivates audience attentiveness and parcticipation.)

4. Conduct an open forum after all teams have completed the PPT presentations. Focus the discussion on the following:

a. Types of plate boundaries (described with examples)

b. Types of plate collisions (described with examples)

c. Movement in major verses minor plates

d. Newton Laws of Motion relative to Plate Tectonics

e. Sea-floor spreading (including magnetic and rock evidence)

f. Convection currents
