Introduction...

The Earth is in crises.  Global temperatures are rising.  Weather patterns are changing.  Numerous species of plants and animals are becoming extinct, and are being replaced by more agressive forms.  Food and resources are dwindling worldwide, and scariest of all, a large meteoroid is on a course that could cause it to strike the Earth.  People are panicking and are worried that the end is near.

Will humans be able to survive?  Can life adapt?  Will there be a tomorrow?

The Task...

You are part of a group of scientists commissioned by the President of the United States to research and present to the United Nations in Geneva, Switzerland a history of life on Earth to help better understand the situation and to possibly give hope that the changes occuring now are not unique in Earth's history.  You are to show how that the events happening today are similar to events that have occurred in the past, and more importantly, you are to show how life has adapted and evolved to these changes that have ocurred.

1.    You and your group members have been assigned a specific time period to research using the links provided and at least three (3) other online resources/websites of your choosing.  Any/all resources used must be properly cited.

2.    Your group will create a PowerPoint presentation to present to the United Nations.  Your presentation must include the geography of the planet's surface, the life forms that existed, and any information about the climate of the Earth during the assigned time period.  Your presentation must include working links to any graphics, videos, images, or other multimedia texts you decide to use (must include at least one).

3.    You will then be asked to write a formal essay that will address questions related to this activity as well as your predictions as to the future of the Earth's environment and people's ability to adapt to any forthcoming changes.  Your essay will be submitted as a blog for others in the class to read and comment on.  You must comment/respond to at least two other student essays.

The Process...

Each science group is assigned and responsible for a specific period of geologic time (for example: the Cretaceous Period, or the Devonian Period)

Within each group, you will have a role to play and will consist of:

The Geologist - The geologist studies how rocks and minerals form, and how they are transported across the Earth's surface.  The geologist will research how the Earth's landmasses have changed through time and determine what the landmasses looked liked during the assigned time period.

The Climotologist - The climotologist will study the effects of Earth's long-term weather patterns on the planet.  The climotologist  will research what the climate was like and how the climate affected the Earth during the assigned time period.

The Paleontologist - The paleontologist studies prehistoric life on Earth through the examination of fossilized plants and animals.  The paleontologist will research what life forms existed on Earth during the assigned time period.

After conducting your research within your particular role, you will collaborate and work with your other science group members to develop a PowerPoint presentation that will include multimedia links to support your findings on the relationship between the geology and climate of the Earth and the life that has existed in the past.  You will present your findings to a full session of the United Nations in Geneva, Switzerland (your class), so will will have to be prepared to present this as professionals (you may have to rehearse your presentation).

All science group members will participate in the presentation to be given and the goal of each group is to show how the relationship between the Earth's geology and climate have resulted in changes in the life that existed on Earth.

Resources...


Each group member can use the following list of resources for their research in their assigned roles.  This is only a small list of possible websites to visit and research, and you must use and cite at least three more in addition to these.  Be sure to use as many primary sources of information as possible.  Additional resources must be valid and reliable (remember how to evaluate a chosen website).  Most importantly, be sure to cite all references used in your project.

Conclusion...

Now that you have completed your research and presented your science group's assigned time period, take a few moments to go over the following questions as you listen to the group presenations of your classmates on their time periods:

First - Would you have been able to surive the time period your group was assigned?  Explain in detail why or why not.

Second - Do you think it is possible for Earth to have another ice age?  What evidence do you have (from your group's research or the other groups' presentations) to support your answer?

Third - Do you think there will be new continents in the Earth's future?  Support your answer with findings from the class presentations.

Last - Do you believe that humans can survive our planet's changing environment in the long term?  What will humans have to do to be able to succeed and flourish in the future?  What do you believe will be in store for us in the future?  Use evidence from the presenations to help support your answer.


Your conclusion should be presented in a well crafted (best academic prose) essay with an introduction, body, and conclusion.  Only word processed essays will be accepted as they are to be posted to a class blog for comment.  You must comment on at least two student essays.

Evaluation...

Students will be evaluated both formally and informally.  Students will be required to present their Powerpoint presentations in their assigned groups to the class.  Participation will be factored into the grade.  A conclusion posted to the class blog based on the presentations will be required of all students.

Grading will be based on the following rubric:

18-20 points = Excellent   12-18 points = Good   9-12 points = Fair   0-8 points = Poor

Objectives
0 Points
3 Points
