Let's start by learning a little bit about Volcanoes!

1. You are going to read about five types of volcanoes. In your notebook, sketch each type, color it, and describe it in your own words (each description needs to include how the volcano type is formed and some information about its shape and size).
2. Also check out four different types of lava. Sketch each type, color it, and describe it.
3. Finally, read about the different types of eruptions. Sketch those if you wish (you don't have to).

Now let's find out what our most active volcano has been up to!

1. Check out the live volcano cam and see what MSH looks like right now then click on the back button to return to this page when you are done, MSH VolcanoCam.
2. Before you go on, check out these pictures.
3. Take out your science notebook. Put today's date, then put Current MSH Sketches as the title.
4. When you have read all these instructions, you will go to the following website:
   MSH Sept 2004 Eruption
5. The above link will open a new window. Keep this window and that one open.
6. At the above website you need to scroll through the page. It shows all that happened on September of 2004! At the top, left-hand corner of each page you will find a link to the next month.
   1. Choose a picture of the lava dome to sketch for each month.
   2. Label each sketch and title each sketch.
   3. Do ONLY the following months: Oct 2004, Dec 2004, Mar 2005, Aug 2005, Oct 2005, Mar 2006, June 2006, Sept 2006, May 2007, Oct 2007, May 2008, Oct 2008, Aug 2009.
7. Read the captions and view the pictures while you create and draw a timeline in your notebook of what happened to Mt Saint Helens since October 26, 2004.

Now combine what you see above with seismographic data!

1. If you go to this website, MSH Webicorder Data (this will open a third window and clicking on seismographs will open a fourth window! Keep them all open and neat!!). You can click on the HSR, JUN, LON or JCW links on the WEBICORDER RECORDS section to see what the seismograph showed on the days that Mt Saint Helens erupted and all the earthquakes that have been happening! Add that information to your timeline. HSR, JUN, LON or JCW are the different seismographs on different parts of the mountain. Remember to keep both windows of Internet Explorer open and just go back and forth between them to compare by clicking on each window. Try it.
2. One more thing, don't get confused when you click on the HSR, JUN, LON or JCW links because those links will open a third window. Once you see the webicorder, you can close that window, but don't close the one with the pictures or the one with the HSR, JUN, LON or JCW links! Remember to click on the right date to match the webicorder with the right picture. Good luck.
3. What conclusions can you draw based on your observations? Remember to back up what you say with evidence from the data you collect (in this case, your observations of the pictures and movies).
