week 7 science 2

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

In lab, we created our model of the sun, 4 inner planets, and our moon, that is according to scale. When creating our model, we had to take distance, size, and shape, into consideration. 

We scaled our solar system using millimeters. We found it hard to make the planets by size because they were so tiny, some being half of a mm. We tried our best to make them to scale. 

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

  1. Preconceptions (standard misconceptions on your topic)

  2. What is the current science understanding?

  3. Other: 

    1. What was the historical version

    2. Cool facts

    3. Women, Iowan’s, other relevant connections?

    4. Etc….

  4. THREE multiple choice test questions, as a team, bold the answer you feel is most correct. 


My daughter had a band concert last night, after the concert we walked home. We were walking to the East and they could see the moon was behind the clouds. They asked me what phase the moon was in since they couldn’t see it. What did I say? 

***The moon was halfway between the horizon and directly above me 

FULL MOON sun in west, moon in east, looking east can she all of the moon 


If you were standing on the Tropic of Cancer, during the summer solstice for the Southern Hemisphere, what direction would you shadow point?

NORTH

 How about if you were on the Tropic of Capricorn? 

NO Shadow, sun is directly above

*** south, north, or no shadow, never east or west***

LUNA 

**during solar eclipse sun disappears**

***LUNar always full moon**

During a solar eclipse the Moon appears to completely cover the Sun, what phase is the moon hit before and after a solar eclipse?

Where did the moon come from? How do you think the moon came into existence? 

Moon came after earth was here, moon is at a different angle only at the same plane twice a year 

Colliding planetesimals, mars sized object slammed into each other shortly after the solar system formed, moon is made of lighter outer material of earth


The Earth takes a year to orbit around the sub, what about the moon? 

28 days

The distance between earth and moon…

Increases by 1.6 inches per year


Sunrise on the moon..How often? 


Moon is rotating, the earth always sees the same side of the moon but the sun does not. The sun sees the other side of the moon


Answer questions about the weekly textbook reading:


What did you learn?

I learned more specifically about the phases of the moon. Moon orbits around the earth and has a total of 9 different phases, it starts with a new moon and ends with a new moon. I also learned more about the equinoix and solstice. During the winter solstice, there is 24 hour light in the south pole. 

What was most helpful?

The images about the difference in winther and summer soltice were most helpful. It was clear to see the difference in the tilt and how that effects the different poles (north and south). 

What do you need more information on?

More information on how the earth tilts, is it just because of the axis that it is always tilted the same degree?

What questions/concerns/comments do you have?

Does being near the equator determine if you have a shadow or not?

week 9 science 2

  The big question addressed in lab, and a description of what you did. We talked about when things  appeared/were created on earth.  our table groups timeline:  4000 mya oldest rock on earth  3400 mya 1st life on earth  2400 mya great oxygenation event  470 mya first land plants  200/300 mya pangea formed  A description of what you learned in Thursday's lecture. we took an exam during lecutre.  Answer questions about the weekly textbook reading What did you learn?  For the text book reading, I completed the practice quiz for our exam.  I learned about the history of the earth by looking at it represented on a clock. It was a different perspective and showed how spread out everythig really is. Humans were not on Earth until close to midnight on the clock example while rocks formed on earth occured so long ago (billions of years)  What was most helpful? The graphics were extremely helpful and descriptive when looking at ear...

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. Earthquakes Plate tectonics  Continental  Ticker, stick up above the water  Averages 20-30 miles thick  Oceanic   In the ocean basin  10 miles thick ...

Week 2

  What did you learn this week? This week, I learned about the 8 characterisitics of life.      -Made of Cells      - Living things produce energy ( Metabolism)     - respond to environment/stimuli      - maintain homeostatis      - genetic information      - movement      - reproduction      - growth and change  2.  How can you apply what you've learned to your teaching in the future? I can apply what I learned this week in the future by teaching my students what the 8 characterstics of life are. I think it is a great reminder to go over these at the beginging of the year since these are a basis for biology and it explains why we do/what we are/why we respond/live, within our environement. 3.  What are new or remaining questions?  After learning about NGSS, a question I have is how to implement these standards in a school district that may not have...
