Two new ideas I learned about __volcanoes__.


 * "The world's most explosive volcanic eruptions usually occur in subduction zones, because subducting oceanic plates are soaked with water, and that water helps the overlying rock melt. Ultimately, the result is a particularly gassy magma."


 * "Scientifically, volcanoes are interesting because they bring you information about the interior of the planet, down to 60 miles or more, and help you study the evolution of the planets, on a human time scale. Mostly in geology you think of processes taking thousands or millions of years."

At least one navigational strategy I used to locate information within a particular website.

On the website pbs.org I utilized the search button. I simply typed in “volcanoes” and clicked on the GO button. The site offered me many choices on the subject called “search results”. I chose SAVAGE EARTH: OUT OF THE INFERNO: VOLCANOES.

At least one reliable source of information about that topic (indicate how you decided the source was a reliable one)

The article __Mountains of Fire__ by Katie Svitil, had references from the Hawaii Volcano Observatory, U.S. Geological Survey, Courtesy of the National Geophysical Data Center. The National Geophysical Data Center (NGDC), located in Boulder, Colorado, is a part of the US Department of Commerce ( [|USDOC] ), National Oceanic & Atmospheric Administration ( [|NOAA] ), National Environmental Satellite, Data and Information Service ( [|NESDIS] ). At least one informational feature you found useful and developmentally appropriate for fourth graders studying this topic.

“No geological phenomenon assails our senses quite like a volcanic eruption. Stay close enough, and you can hear the explosion, see the fire fountaining, smell the gases, feel the ground tremble, taste the ash in your mouth. "I think that is why volcanoes are so cool to grade school kids," says Chris Nye, a volcanologist at the Alaska Volcano Observatory in Anchorage.

Internet Researcher______________________________ Date ____________________

Objectives This Internet workshop will introduce you to our lesson on researching volcanoes. You will have the opportunity to utilize the internet for this lesson. You will learn how volcanoes erupt and famous names and locations of volcanoes. You will learn how to figure out if the site is reliable or not. Don’t forget to take careful notes in your internet journals so you can share them later in our internet workshop session.

Famous Volcanoes.

_______________________________________________________________________________________________________________________________________________________________________________________________________________
 * 1) Go to the bookmark I have set up for Kids Web Volcanoes [|www.pbs.org/wnet/savageearth/volcanoes/] and click on the tab Side Bar One. It should feature Volcanoes of North America. Mt. St. Helens is the most famous volcano but can you name four others and where they are located? Pick one and write two facts about it also.

Volcano Vocabulary

_______________________________________________________________________________________________________________________________________________________________________________________________________________
 * 1) What makes a volcano? What is magma? What is a magma chamber? What is a mantle? What is lava? What is a subduction zone? Where can a subduction zone be located? What does a stratovolcano look like?

Critical Thinking

3. Be a detective. What clues can you find on this site that indicates part of the information featured comes from the Hawaii Volcano Observatory, U.S. Geological Survey, and the National Geophysical Data Center? Write them down and bring them to the internet workshop session. How did you find them? What strategies did you use? ________________________________________________________________________________________________________________________________________________________________________________________________________________________
