Introduction

While many people would find the Galapagos Islands a place of beauty and relaxation, a biologist or geologist would find it to one of the world's greatest natural laboratories.

Task

The students will research the geology and climate of the Galapagos Islands and describe how this effects Darwin's mechanism of natural selection.  The gathered data will be presented as a paper and a PowerPoint presentation.

Process

Use the following six websites to do research for your paper and presentation:

Galapagos Geology on the Web: A brief Introduction to the Geology of the Galapagos

Galapagos Geology on the Web: Galapagos Climate and Oceanography

Galapagos Geology on the Web: A brief history of the Galapagos - Darwin and Evolution

Evolution and Natural Selection

Darwin's Finches

News Release: Galapagos Finches Sing Different Mating Songs Due to Evolutionary Diversification of Beaks, Says UMass Biologist

 

Answer the following questions in your paper and your presentation:

What is a mantle plume?

What is its relationship to the Galapagos?

Explain the process that formed the Galapagos Archipelago.

How are the Galapagos Islands like the Hawaiian Islands (Talk about plate tectonics)?

What type of volcanoes are found in the Galapagos?

Explain the oceanographic processes that shape the climate of the Galapagos. (Include currents, upwelling, Ekman Transport, and Southern Oscillation)

How is the climate related to natural selection?

What is natural selection?

What did Darwin do?

What are the requirements of natural selection?

What evidence is there to support natural selection?

How do Darwin's Finches relate to natural selection?

How do their beaks relate to mating calls?

 

The paper should be five typed pages in 12-pont Times New Roman font.  You should include a title page and reference page.  The PowerPoint presentation should run 10 minutes including time for questions.  There should be at least 10 slides.  See rubric for more detailed instructions concerning this assignment.

 

Evaluation

Students will be evaluated on there paper and PowerPoint using the following rubric:

Teachers

Grade Band: 9-12 Geology

Tennessee State Standards: 9-12 Geology 

4.4 interpret and evaluate the fossil record for evidence of biological evolution.

4.5 demonstrate the effect of the environment in the formation and extinction of species through geologic time using fossils.

5.1 recognize different types of plate boundaries (e.g., divergent, convergent, and transform including continental vs. oceanic).

5.2 interpret evidence for plate tectonics using paleomagnetism, fossil record, continental boundaries, and hot spots.

5.3 recognize that convection currents are the driving mechanisms for plate tectonics.

5.4 describe the processes associated with volcanoes, earthquakes, and mountain building.

Grade Band: 9-12 Earth Science

Tennessee State Standards: 9-12 Earth Science 

 3.1 explain the components of the tectonic cycle.

4.3 interpret and evaluate the evidence for biological evolution in the fossil record.

4.4 demonstrate the effect of the environment on the formation and extinction of species.

Grade Band: 9-12 Life Science

Tennessee State Standards: 9-12 Life Science 

6.2 interpret various forms of evidence for biological evolution.

6.4 relate environmental change to natural selection, mutation, and adaptation that may lead to the emergence of a new species or the extinction of an existing species.

6.5 use current knowledge of DNA and comparative anatomy as evidence for biological change.

Grade Band: 9-12 Biology I

Tennessee State Standards: 9-12 Biology I

6.2 investigate how natural selection, mutation, and adaptation impact a species.

6.3 recognize the contributions of scientists, including Darwin, to the concept of evolution.

6.4 apply current knowledge of DNA and comparative anatomy to provide evidence for biological evolution.

Grade Band: 9-12 AP Biology

The College Board: 9-12 AP Biology

Evolution: Evidence and Mechanisms

 

Purpose: To encourage students to learn about the origin of Darwin's mechanism of natural selection and its connection to the geology and climate of the Galapagops Islands through the exciting use of the Internet.  To encourage the presentation of data through a paper and a PowerPoint presentation.

Preceding and Ensuing Events of Instruction: The teacher should first show the IMAX movie Galapagos (39 minutes) which is available through slingshot.  This should prompt student interest in the topics covered in this WebQuest.  Ordering information at www.slingshotdvd.com

This WebQuest can prompt future interest of students in the field of geology and biology.

Teachers will need to procure geology and biology textbooks for reference. 

Learning Improvements: Students will be allowed to do independent research which should lead to a move away from extrinsic rewards to greater intrinsic rewards.  Learning will be reinforced when the students assemble and evaluate the research they have done.

Improvements and Expansions:  This WebQuest can be expanded by investigating other species on the Galapagos Islands that lend evidence to Darwin's theory.
