  Week 13 ALL UPDATED Lab: We began by talking about inquiry based learning and also climate changes overwhelming affect on almost everything. For example Aly mentioned that climate change has affected covid 19 because when deforestation occurs, and humans ruin wild life habitats, the wild animals that live in that live in these habitats will start intermixing with humans and they carry thousands of unknown diseases that can cause pandemics. We then each read different articles about climate change in Iowa and learned that the high temperatures will double in the next two decades. This effects our economic systems, health, and can cause flooding in Iowa.  Teachers who teach about climate change sometimes avoid it, and also teach wrong information that what is occurring is natural.  Lecture New Thoughts: Climate Change Again, climate can only be measured over 30 years, anything less and it is considered weather.  almost 14k peer reviewed articles on climate change, an...

  Week 12 I did not have a previous blog last semester to update.  Climate and Weather Climate is a 30 year average of the weather. Weather is whatever it is that day or week or month. Climate is a personality and weather is the mood. S omeone with a great personality who is always bubbly and happy can also just have a bad day. Same concept as climate and weathering.  Before the flood: Common themes- Caused by humans, oil, coal, people not believing in climate change, big corporations and their roles, and poor people were affected the most. What questions to address- What will our new normal look like? (societal/economical) What other things are being affected? Why is renewable energy not used more? How can we make them more affordable? If we invested would the US be able to use more renewable energy soon? How could we address them- Through labs and hands on experimentation. I would prefer that over lectures.  The percentage of precipitation is increasing in America...

  Week 11 Lab Law of Superposition: Oldest rocks are at the bottom Igneous means born from fire If an igneous molten lava came and tried pushing through the rocks it tips the layers of the rocks. Anything that tilted is older than the lava. Every new layer of rock on top of that will lay flat.  We then went over the Sweater Article, we discussed the power we have as teachers and how we have to understand the flaws of the system before we can be better.  Next we analyzed sand from all over the world under a microscope.  Lecture Water, wind, and glaciers are the forms of erosion (moving material). Wind erosion can only move small particles, but they can eat away at larger.  Principles of wind erosion: Wind shadows- areas behind an object where wind speed slows down and material is deposited Carves the earth  Sand created through water is polished, smooth, and generally similar in size.  Sand created through glaciers is polished, smooth, but irregular in...

  Week 10 Lab: We melted starburst to create each of the different types of rocks. Sedimentary, igneous, and metamorphic. Cooling- EXTRUSIVE: Exit earth,  cool fast (water/air) small crystals INTRUSIVE: Inside earth, insulated by earth, large crystals Weathering and Erosion- Mechanical/Physical: Does NOT change the rock Chemical: Changes the rock Assessments: You can't see the growth of a student unless you know where they start.  Layers of the earth: Core inner core- solid Core outer core.  Mantle- liquid Crust How do we know the crust is solid? When an earthquake happens in the crust and is measured with a seismograph, just like ripples in a pond when the earthquake hits something solid we feel the echos of it back on the surface. The side that the earthquake didn't hit is a dead spot, meaning it is solid because it could not go through.  Notes: Continental plates are two converging boundaries shift one goes over the other and creates a mountain.  Two oce...

  Week 9 In this lab we reviewed questions for the exam on Thursday. We then mapped out the timeline of the creation of earth, and life. We mapped out on the timeline starting with the big bang, then started at the creation of earth, the moon, first land life, plant life, dinosaurs, and lastly humans. We all guessed on where we thought they would be. We then went on the earth viewer website and found the actually dates. We put them on the timeline then discussed it as a class and realized how off we were.  Old Lab 13.7 billion years ago is when the big bang occurred. 4.65 billion years ago is when the earth was created, our sun will last for ten billion years. There was a star that existed between the big bang and the creation of our sun. But because it was a huge star it burnt its fuel fast and a supernova occurred. The debris from the first star came together and 99.9 percent was gobbled up by the sun and the last one percent of the debris is what created the planets. We did...

 Week 8  New Lecture: 13.7 billion years ago there was nothing and nowhere. The big bang occurred 13.7 billion years ago, earth was formed much later.  We call it the big bang but nothing exploded, it was more of an expansion . Nothing became something. Stars: light did not happen until 300,000 years AFTER the Big Bang Stars and Galaxies began to form about 12.7 billion years ago The sun formed from a stellar nebula which is dust and debris, most likely from a star that underwent a supernova.  The sun is 4.65 billion years old and is half way through its full supply Red giants are huge and bur fuel and lose mass, which then increases size due to less mass Nuclear Fusion - Stars can make up to iron on the periodic table of elements Every element in our universe came from the explosion of a star Origin of the Earth: Created 4.65 billion years ago NOT IN THE BIG BANG The big bang happened and it created a red giant. The red giant blew up and the Dust and debris created...
