week 10 science 2

 The big question addressed in lab, and a description of what you did.

In lab we discussed how we decide if something is a rock. 

- coal, hardended lava, limestone, gravestone, iron ore, marble statue, and granite. 

we also discussed the importance of how to asses our students as well as how to create activities that are relavent to their questions and prior knowledge 

we also discussed the layers of the earth

- core (heat), mantle, crust (tectonic plates) 

when tectonic plates collide they can create mountains, if land and water plate tectonic occur one goes on top of the other 

igneous rocks- when magma cools

sedimentary - compaction and cementation (squished together) 

metamorphic - heat and pressure 





A description of what you learned in Thursday's lecture.

  1. Earthquakes

  2. Plate tectonics 

    1. Continental 

      1. Ticker, stick up above the water 

      2. Averages 20-30 miles thick 

    2. Oceanic  

      1. In the ocean basin 

      2. 10 miles thick 

    3. If oceanic and continental plate hit, oceanic loses and goes under 

    4. Hawaii: Hot Spot


  3. Rock cycle 

Layers of the Earth 

Inner core, outer core, mantle, crust 


average mm/yr - sea floor spreading is measured using this scale




Answer questions about the weekly textbook reading:

What did you learn?

I learned about the three types of tecnonic plates. I understood the basis of what occurs with each plate however from the book and lecuture, I learned more in depth why it happens and where. 

1. transform boundary 

2. convergent boundary 

3. divergent boundary 

I also learned about volcanos and what the 'ring of fire' is. Earthquake acitivty occurs mostly on the coasts of continents. 

What was most helpful?

It was helpful having the descriptions of the two different types of eruptions. I remember learning a little about it in natural disasters class but the brief overview was helpful. 

What do you need more information on?

More information on the lithosphere and asthenspere would be helpful, the picture of tectonic plate boundaries. 

What questions/concerns/comments do you have?

Do fossils have an effect on volcanos or earthquakes? How deep down in earths layers can fossils be found?

  The big question addressed in lab, and a description of what you did. video notes  - 2020- hottest decade ever, largest number of mega-fires, caused by lots of droughts - fumes having impact on planet  - fires are now occuring annualy since earth is warming and droughts are more common  - sun is dominant source of energy  - carbon dixode peeked then went down then went back up again - plants takeup CO2 from atomospehere during summer, winter decomposition - caused by veggitation in northern hemisphere  - plant matter made up more of carbon 12 than carbon 13  - carbon coming from volanos have different ratios  Greenhouse effect  - image in presentation  Earths blenket and light  - certain gases in our atmosphere act like a blanket around the earth  - light rays coming from the sun contain visble photons (energetic light particles)  - abosrbed by earths surface A description of what you learned in Thursday's lecture.

week 11 science 2

  The big question addressed in lab, and a description of what you did. We started lab having small and whole group discussion about formative assessments and teaching students based off of their questions. Next, we did an activity to determine 'who came first' which translates to how we are currently learning about things in earths history that occured first. We did an invesigation to determine what came fist in the principle of superposition.  - rocks form layers that become buried under more layers over time, the deeper we dig, the farther back in time we see. Fossils found deeper and deeper mean it gets older and older.  We also looked at the layers of earth.  1. sandstone  2. mudstone  3. limestone 4. volcanic ash  5. granite (shifts up, lead to fault line)  sand created through water is polished, smooth, similar in size  glaciers, polished, smooth, irregualr in size  wind  A description of what you learned in Thursda...

  The big question addressed in lab, and a description of what you did. REVIEW: Different types of sand:  water (ocean)- polished,  smooth, similar in size  glaciers - polished, smooth, irregular  wind (dune) - opaque, fine grained, frosted, pitted  characteristics of water eriosion  - (1) headwaters, most gravity, moving faster, can carry mroe sediment - (2) TRANSFER ZONE, starts slowing down (3) depositional zone, U shaped river basin  when glaciers move acorss land, make U shaped valleys, not moving super fast  Transitioned into Climate Science  Measuring & Mapping, Precipitation in Iowa  How do we know if the goldfinch is in danger in Iowa?  I think they are starting to become endarged due to the evidence, but slowly. There has been an increase in rainfall which makes it harder for birds to survive.  A description of what you learned in Thursday's lecture. We took an exam during lecture.  Answer questions abou...
