2: My name is Zander Ho, I'm 14 years old and I'm going into 9th grade. I love technology, especially robotics. I'm a boy scout and love the outdoors. When I heard about the STEM class I thought it was so cool. At first I didn't like the class because I didn't know anybody else but after we went to Oregon we all knew each other and we were all friends. At first, the teachers were like any other teacher you would find in a school but after Oregon we knew each other better. For photography I never thought I would be this interested in it, but I love it. I wanted to learn how track from the start and we are very lucky to have worked with the people that we did. I hope to travel to South Africa next summer with the STEM class. | Student Biography
5: Dave Clayton works as a wildlife biologist for the U.S. Fish and Wildlife Service in the Rogue River National Forest near Ashland, Oregon. Dave is conducting research on wolves and fishers. He has several fishers with radio-collars he is tracking and he invited us into the field one day during our visit. While in the field, we learned how Dave uses data tracking to study how fisher populations are affected by deforestation. When we were with him, we learned about his line of work and we got to use the radio-trackers to find a radio-collar out in the forest. | Scientist in the Field
6: Geology | The Cascades are a volcanic mountain range in northern California, Oregon and Washington that were formed by plate tectonics. The plate tectonic setting in the Cascade Mountains is a convergent plate boundary which means that here the plates are moving toward each other. Alfred Wegener was the man who proposed the continental drift hypothesis that later led to the discovery of the plate tectonics theory which was proven many decades after he died. The plate tectonics theory is the theory that giant plates of rock in the lithosphere move around on a soft layer of the mantle called the asthenosphere carrying the continents around with them. The Cascade Mountains formed when the Juan de Fuca Plate and the North American Plate collided. When plates move toward each other, if both plates are continental then they will both rise at the boundary to form mountains. If one is an oceanic plate, the oceanic plate will create a subduction zone. In a subduction zone, the denser oceanic plate dives down under the buoyant continental plate. The mantle above the subduction zone melts, forming magma, which rises to the surface creating a volcano. Mount Mazama, now called Crater Lake, is an example of this geologic process.
9: Mount Mazama was a very large composite volcano that erupted 7,700 years ago. It was estimated to be 12,000 feet in elevation. When Mount Mazama erupted, it blew a mile wide column of ash into the sky and pyroclastic flows rushed down on all sides of the volcano. The ash from the eruption traveled as far east as the midwestern United States, and the pyroclastic flows traveled at speeds more than 200 mph towards California. The eruption 7,700 years ago emptied the magma chamber under Mount Mazama. The empty magma chamber was unable to hold up Mount Mazama so it collapsed and created a caldera which is now home to Crater Lake. A caldera is a large volcanic depression formed from an explosive eruption. After the collapse several small eruptions occurred creating Wizard Island, which is a cinder cone volcano, Merriam Cone, a lava dome, and the Central Platform. The volcano has not erupted since, but the magma chamber is slowly refilling. Crater Lake is the deepest lake in the United States and the seventh deepest in the world. Crater Lake is 1,949 ft deep.
12: For the picture on the right I would have changed the aperture to a higher number so more of the moss is clear or I would have focused on the moss closer to me instead of the moss in the middle. | Critique

38: Radio tracking is when while tracking an animal, a radio signal is being used. Sometimes a chip is put into the animal and sometimes a collar is put on them the locate where they are. When tracking for fishers, Dave Clayton traps them, then he sedates them so he can study them to make sure they are healthy and if they have not been caught before he puts a collar on them and let's them free. How this works is that the collar sends a radio signal to be picked up by a satellite or an antenna. The antenna is used to track them on foot to find there precise location if you are tracking them.
