 * Three new facts about volcanoes:

- The largest volcano on earth is Mauna Loa in Hawaii. It's 6 miles tall from the sea floor to the summit. Coffee is able to grow in the fertile soil around the volcano. - The word "volcano" comes from the Roman god of fire, Vulcan, who was believed to melt and shape iron on the Italian volcano called Vulcano. - Magma, or liquid rock, is inside a volcano. When it comes out, it is called lava. Gases and pyroclastic debris also erupt from volcanoes.


 * One navigational strategy I used:

- I clicked on links to bring me to different pages with volcano information, such as diagrams, activities and different types of facts (background information, types of volcanoes, etc.). Whenever I was done, I would press backspace to go to the main page or to the EDC423 Wikispace to look for more pages.


 * One reliable source:

- Enchantedlearning.com is a user-supported site, so it may not be as scientific as say, the Discovery Kids website, but usually teachers use it and add to it, so I consider it reliable.


 * Two informational features that are useful and developmentally appropriate for fourth-graders:

- The volcano cross-section picture on enchantedlearning.com is really helpful because it shows exactly how a volcano works and what it is made of. - The volcano of the month on the Facts about Volcanoes website is also great for fourth-graders because it shows pictures of real volcanoes from space. What do kids like more than lava and erupting volcanoes besides outer space??
