Earth Science Content
The interests of research scientists range widely, as exemplified by today’s talk by Dr. Dallas Abbott. Much of her work has investigated the thermal history of the earth, and the manner in which heat transport through the crust and upper mantle influences geological processes, both ancient and present-day. But during the course of such investigations, she noticed evidence that the intensity of mantle plumes (e.g. Hawaii) might be the result of meteorite and other objects crashing into the Earth’s oceans. Dr. Abbott will share some of this evidence, describe the techniques she uses to explore these problems, and discuss where future investigations may lead in our knowledge of Earth’s past and future.
Integrating Educational Technologies
WebQuests: a Web Strategy to Get Your Students Involved!
WebQuests were created by Dr. Bernie Dodge and Tom March in 1995, at the San Diego State University. They have become such a popular strategy for teaching with the web, that many materials and tools have been developed to help newcomers (and more savvy users as well!) to develop a WebQuest of their own.
You can learn to build your own WebQuest by doing this tutorial:

This online Workshop has been set up in an order that guides you through the main steps of building a WebQuest, as well as guiding your reading so that you have the background information necessary to understand the concept.
We challenge you to try using this new teaching strategy for yourself. You’ll be amazed at how involved your students become. And it’s one of the best ways to use the resources available to you in this website!
Good luck in your quest!

Class Assignments
Based on the information you have learned about Impact Craters and WebQuests, think about how you could modify the way you teach this topic to make it more meaningful to your students.
Share your ideas with the group, using the virtual classroom, to discuss:
1. Why it is important for students to learn about impact craters and scientists to study about them. (contextualize the topic).
2. How you could use the WebQuest format to get your students more involved in thinking and acting scientifically.
