Kesler Science Station Lab Volcanoes If you have never used my Kesler Science Station Labs before please download the FREE Start-Up pack from my TPT store. It will provide you with all of the signage and best practices in order to run the station labs in your classroom. The large directions cards included in this file are intended to be read by the leader of the group once the students get to the station. The smaller task cards can be read by another group member. I prefer that each student do their own lab write-up (included at the end of this file), so that they may use it for reference at a later date. The answer key is provided at the end of the document. Lastly, if any of the internet resources no longer work for some reason please let me know via email at chris@keslerscience.com. I cannot guarantee that all resources will be available, but I tried to choose ones that have been around for many years.
Kesler Science Station Lab Volcanoes Teacher Directions Explore It! I will spend much of my time at this station making sure the students are not wasting time. You will need the included cards and some cans of playdoh. Illustrate It! Normally this station would be an output station, but in this lab I chose to use it as an input station. You may want to setup computers for research. Read It! Print several different copies (I use 6) of the reading passage so that multiple students can read at different paces Watch It!

Read It! Station Directions Each member of the group will read the passage and answer the questions from the task cards on the lab sheet in the Read It! section. It is important to remember that the answers will come directly from the reading passage.
Where do Volcanoes Form? There are three main places where volcanoes originate: hot spots, divergent plate boundaries (such as rifts and mid-ocean ridges), and convergent plate boundaries (subduction zones). The origin of the magma for hot spots is not well known. We do know that the magma comes from partial melting within the upper mantle, probably from depths not too much greater than 100 km. The actual source of the heat that causes the partial melting (the actual hotspot itself) is almost certainly much deeper than that, but we really don't know how deep. At a divergent boundary, two tectonic plates are moving apart. Magma that is generated in the upper mantle flows upward to fill in the space. This magma is probably generated at depths that are shallower than those for hotspot magmas. People argue about whether the magma forcing its way to the surface causes the plates to move apart or whether the plates move apart and the magma just reacts to that and fills in the space. Perhaps it is a combination of these two. The most extensive example of this type of volcanism is the system of mid-ocean ridges. Continental examples include the East African Rift, the West Antarctic Rift, and the Basin and Range Province in the southwestern US. The final major place where volcanism originates is at convergent boundaries (subduction zones)--where an oceanic plate dives under either another oceanic plate or perhaps a continental plate. As the plate gets pushed further and further it starts to give off its volatiles (mostly water), and these migrate upwards into the mantle just under the overriding plate. The addition of these volatiles to this overriding mantle probably lowers the melting point of that mantle so that magma is generated. Part of the magma may also be generated by the downward moving plate actually starting to melt as it gets into the hotter and hotter interior.
Where would you least likely find a new volcano? A. Mid-ocean ridge B. Hot spot in Hawaii C. The great plains in the middle of the U.S. D. Near a subduction zone in Argentina How do volcanoes form near a divergent boundary? A. Magma fills in the gap where the plates move apart B. Magma is created by a subduction zone C. Magma breaks through the tectonic plate above a hot spot D. Mountains erode away and create a volcano A is formed when one tectonic plate dives underneath another one. A. hot spot B. subduction Zone C. rift Valley D. divergent plate boundary Which statement can be concluded after reading the passage? A. There are many volcanoes formed near plate boundaries. B. Volcanoes are created by erosion and weathering. C. A convergent boundary must be present to form a volcano.

Task Card #1: Volcanoes are typically created over a hot spot, at a divergent boundary or at a convergent boundary. Task Card #2: A composite volcano is a more traditional looking volcano and has a caldera and vent at the top. It has steep slopes and capable of massive eruptions in a short time period. Shield volcanoes are created by flowing magma and have gentle slopes. Their eruptions are less violent and generally last a longer period of time. Task Card #3: Both divergent and convergent plate boundaries can create volcanoes. Magma seeps in a divergent boundary to create volcanoes. When one tectonic plate submerges underneath another one a volcano can form by the melting Earth. It is formed on the tectonic plate that isn t submerging.

Students should be able to recognize that volcanoes are grouped together in lines. They may not connect that these are also plate boundaries. Task Card #2: 1. Hot spots originate deep inside Earth, so they remain stationary while the plates above them move. The magma associated with hot spots is mafic, so shield volcanoes are commonly formed 2. Spreading centers are places where tectonic plates are diverging (moving away from one another). As the plates separate, a pathway is created for magma to move toward the surface. 3. Subduction occurs when two tectonic plates converge, and the denser of the two plates is pushed beneath the other plate. Volcanism will be present at the leading edge of the top plate. When a continental plate and oceanic plate converge, the denser oceanic plate is subducted. The descending plate is heated by pressure and Earth's geothermal gradient. This leads to the formation of magma. The magma rises to the surface, and a belt of composite volcanoes forms. Organize It!
Volcanoes Answer Key Watch It! Task Card #2: Hundreds of years ago scientists used to believe that volcanoes were burning mountains of fire, but today we know they are vents that open to the interior of the planet. Task Card #3: Most volcanoes are found on or near plate boundaries because one tectonic plate is either converging or diverging away from each other and volcanoes are created. During subduction magma is produced and surfaces at weak points in the tectonic plate. Task Card #4: A composite volcano has massive, sudden, and explosive eruptions. Shield volcanoes are constantly erupting and are much more gentle with their eruptions.
