Volcanoes

This video demonstrates a science experiment on the formation of calderas.  The idea is great.  Either show the video or demonstrate the formation with your students.

A limnic eruption occurs when a poisonous gas gets "belched" out of the bottom of a lake where it was building up pressure.  This video discusses 2 famous limnic eruptions and what scientists are doing about them.

In this demonstration, students will get a better understanding of what a geyser is and what makes it function the way it does.  I was worried about trying this at the high school earth science level because it is a bit elementary, but the science is sound, and it works.  Materials needed are:

I show this video during my unit on volcanoes when discussing the two Hawaiian volcano flow types, Pahoehoe and aa lavas.  It shows both very well and I have the students shout out what type as the video plays.  There is also a great view as to what a shield volcano looks like so I pause it at that point to discuss why a shield volcano takes on the shape that it does.  I also talk about the cooling of the lava and how it hardens and turns into solid basalt.

In this volcano video, students will be able to see a climb up Krakatoa's child, Anak.  I find this video fascinating because it vividly shows the results of recent volcanic activity.  Your students will be able to witness what fine ash looks like and how fragments are ejected from the volcano. 

This is a short video that does a good job describing the Yellowstone Supervolcano. It does a great job showing the potential of large magma chambers.  This volcano video will also talk about how much ash can fall in some places after very large eruptions.

I show this video when discussing the different types of volcanic eruptions.  This volcanic eruption style is a Hawaiian style.  The lava does a great job demonstrating Pahoehoe and Aa lava types.

Experience the awe-inspiring power of a strombolian eruption with this fascinating video found on EducationalResource.org. This video is an excellent resource for educators looking to supplement lessons on volcanic eruptions and the different types that exist. Through stunning visuals and clear explanations, viewers will gain a deeper understanding of what a strombolian eruption is and how it differs from other types of eruptions.

I show this volcanic eruption when trying to discuss the different types of eruptions.  This one is called a Vulcanian eruption.
