Description
This lesson explains the application of relative dating for volcanic features in the ocean. The initial lecture focuses on the concept of relative dating. Relative dating of island chains was a fundamental step toward the development of the hotspot theory utilized over 100 years before the hotspot theory was introduced. The goal of this lesson is to prepare students to make predictions of the relative age of volcanoes based on predictable progressions. Lesson duration: Approximately 35 minutes. |

Description
This lesson defines hotspot volcanoes and the major contributor to the theory. It also discusses the importance of the hotspot theory and how hotspot island and seamount chains can be used to determine absolute plate motion. The goal of this lesson is for students to gain an understanding of hotspots and their useful applications in geosciences. Lesson duration: Approximately 35 minutes. |

Description
This lesson explains a theory on magma generation at hotspots called the mantle plume theory as well as possible ways of finding evidence to support the theory. The goal of this lesson is to introduce students to a theory that scientists are actively trying to evidence or refute. Through this students will learn about mantle tomography which helps scientists make predictions about the inside of the earth. Lesson duration: Approximately 25 minutes. |
|
Instructions
The lesson is shorter than the others in case extra class time is needed to catch up on the previous days activities. |

Description
This lesson makes comparisons between Hawaii and Samoa in an attempt to determine the volcanic origin of Samoa. The goal of this lesson is for the students to formulate hypotheses based on evidence from Samoa and make predictions based on their hypotheses. Lesson duration: Approximately 20 minutes. |

Description
This lesson describes how science is conducted, from collecting samples, to processing the material and determining the results. This presentation is a summary of what Jamie does as a masters student at Scripps Institution of Oceanography. The goal of this lesson is to introduce students to some aspect of science that they may not have previously been familiar with. Lesson duration: Approximately 45 minutes. |
