Plate tectonics

Assignments:Understanding Goal # 1Which are the different kind of faults? and make working models of them.Statement: Students will understand the different kinds of faults, the sources of energy and how they interact in the borders of the plates.Performances of UnderstandingThe students will make working models of the three kinds of fault and describe. How they can be identified, and describe the consequences of their movement.The students will display their understanding of the way these models work by showing during their presentations the ways in which the forces behind their models make them work. Explain what are the similarities and differences between the San Andres fault and what happened in Haiti.
Understanding Goal # 2 Question: How scientists pinpoint the epicenter of earthquakes?Statement: Students will understand way scientists measure the epicenter of earthquakes.Performances of Understandinga) Using http://www.sciencecourseware.org/eecindex.php The students will be able to learn how scientists can pinpoint the epicenter of an earthquakeOngoing AssessmentsAt the end of activity a) the students will print their own certificate of copmplition of the activity that demonstrates they mastered the concepts involved in the detection of epicenters.Understanding
Goal # 3How the different plates interact with each other and what effect they have on the environment?Statement: Students will understand the different ways in which these processes modify the surface of the Earth.Performances of Understandingb) Using appropriate software the students obtain first hand knowledge of the places where earthquakes occur and therefore understand where the borders of the different faults are.c. By plotting on a world map the position of the last five years volcano eruptions the learners obtain first hand information of the relationship between volcanoes and the borders of the different plates of the Planet.Ongoing AssessmentsAfter they plot the different earthquakes and volcano eruptions of the last five years the students are asked to compare their results with those shown on the programs and write their conclusions.
Understanding Goal # 4What effect volcanic eruptions have on the environment? And Why people settle near them?Statement: Students will understand the effect of volcanic eruptions on the environment, and the reasons why people tend to settle in their vicinity.Performances of Understandingd) Research on the effect of recent and past volcanic explosions on the environment using videos, Scientific articles, Encyclopedias and the different resources on the Internet and the school library.Ongoing AssessmentsBy using the rubrics provided the students and teacher will know what is expected from their investigation.Understanding Goal # 4What effect volcanic eruptions have on the environment? And Why people settle near them?Statement: Students will understand the effect of volcanic eruptions on the environment, and the reasons why people tend to settle in their vicinity.Performances of UnderstandingThe learners divided in groups of four investigate each of the major sites where volcanic eruptions have affected the environment in the past: 1. Santorini Island eruption of 1628 BC 2. Pompeii 79 AD 3. Krakatoa 1883 AD 4. Mount St. Helen 1980 5. Pinatubo 1991 AD 6. Toba, Sumatra 55 000 BC 7. Yellowstone 620 000 BC The project should address amount of material send out by the explosion, frequency at which these volcanoes erupt. The student should make special emphasis on the effect of the eruptions on the environment, on the species in the near area, and civilizations if any around the site when they erupted. Also the project should contain information on the effect on the weather and what can be done to minimize the effect of these disasters on the population of the area.
Ongoing AssessmentsThe culminating project should be presented (using Power Point presentation or Flash) to the class by each group and at the end the class as a group should make a list of recommendations of solutions for disasters of this kind.
