Week 9

1. What did you do in Lab?

  • Kahoot to prepare for the test
  • Engaged our preconceptions about the timeline of the Earth
  • Earthviewer simulation

2. What was the big question?

What are the significant events in the history of the Earth?

  • A lot has happened in the last 500 million years
  • The Genus Homo did not appear until 2 million years ago and Homo Sapiens well after that
  • Pangea formed 300 million years ago
  • Largest extinction in Earths history occurred about 250 million years ago

3. What did you learn in Thursday Discussion?

  • We had an exam in Thursdays class

4. Textbook

       1. What did you learn?

  • If the entirety of the Earth's history was a clock, humans would appear at 11:59:40 PM. 
  • Earth is over 4 billion years old
  • Snowball Earth- the Earth was engulfed entirely in ice
  • The continents moved over time, first known as continental drift
  • A new supercontinent could form in 250 million years

       2. What was most helpful? 

Reading more about Pangea. I learned about Pangea throughout my history in science courses, but do not know much other than that the continents were connected. The diagrams helped make the timeline more clear. 

       3. What do you need more information on? 

I look forward to learning about the plate tectonics theory in the next chapter.

       5. What questions, concerns and or comments do you have?  

Could we have another period of a snowball Earth in the future?

 1. What did you do in Lab? Formative Assessment- Is it a rock? Discussed "Activity Mania"  Discussed Assessment How do we assess our students? Tests, projects, homework assignments, observations, etc. What does it mean to get an "A"? Grade inflation Danger of comparing students using percentages Layers of the Earth Convection currents Starburst rock cycle 2. What was the big question? How can we create sedimentary, igneous and metamorphic rocks with starbursts? Sedimentary- Compacted starburst together with no heat added.  Igneous- melted the starburst and let them cool. Metamorphic- Compacted starburst together and use little heat so they did not melt. 3. What did you learn in Thursday Discussion? Sand on the beach came from distant mountains and landforms Diverging plates go away from each other. Make ridges. Converging plates go towards each other. Make trenches.  Hawaii hot spot We measure plate movement in mm/yr Oceanic plates do not move at a consistent rate ...

Week 11

 1. What did you do in Lab? Discussed the previous weeks homework, "Sweater Article" Learned about the law of superposition Rocks that are further down are older. This helps determine the relative ages of layers of rock. An intrusion is the youngest of the rock that it goes through Determined oldest -> youngest in layers of rock Discussed weathering and erosion the process by which rocks are attacked by the environment Characteristics of sand activity with a microscope 2. What was the big question? What are the different types of erosion and what do they form? 3. What did you learn in Thursday Discussion? Buoyancy/ water displacement experiment  Archimedes principle Geode is the Iowa state rock You can use gravity to determine if a geode is hollow 4. Textbook         1. What did you learn? Rocks are classified as three types: Igneous Sedimentary Metamorphic The key processes in the rock cycle are heat and pressure and weathering and erosion A geode forms...
