On Thursday, 9th February 2017, we took science out into the field and went to discover more about our local environment in the arroyo in front of our school. Marcus Johnson long ago brought The Sierra School Science teacher, Tom Ekman, to BCS when Tom was a college student. They did a field study trip to learn about the amazing geology in BCS. Johnson was Tom’s geology professor when he was an undergraduate student at Williams College. Johnson is a specialist in Baja Geology and we had a lot to learn from him. He gave us 2 lectures and lead us on an amazing field trip.
Before leaving the school with Marcus Johnson, we learned about the three types of rocks; igneous rocks, such as granite, hypabyssal and metamorphic rocks, sedimentary rocks, such as limestone, sandstone and shale. We learned how all of these rocks contain minerals, composed of elements. After that, we classified rocks into the three groups, and we learned how they all contain salt. Professor Markus talked to us about how geology is influenced by weather: he talked about hurricanes, which are formed by rough winds, and rain, which later produce flash floods.
In addition, we looked at La Niña and El Niño conditions. El Niño conditions are stronger, rougher, and windier; and in the future we will have more, evidence of global climate change. El Niño conditions form by soaking up of a lot of warm water linked to global warming. La Niña conditions are average hurricanes; the most common and normal ones.
