Week 2: Space: The Final Frontier

 1. What did you do in lab today? We didn't have lab this week due to holiday.

2. What was the big question? How did the Space Race shape our understanding of space and technology?

3. What did you learn in Thursday's discussion? 
Notes:

Greek Astronomer Eratosthenes, 240 B.C.E measured the size of the earth 
- he hired a pacer to help him measure the size of the Earth (800 km) 

Sputnik and the Space Race: 
- 1957 Russia launches satellite
- 1969 Neil Armstrong and Buzz Aldrin land 
- December 1972 last time on the moon 
- America was falling behind the Russians in space exploration --> 1961 Alan Shepard into space

Right Stuff/Wrong Gender
Women preferred to men due to generalizations: 
1. lighter
2. shorter
3. consumed less food 

Future of space travel
1. return to the moon in 2019 --> didn't happen
2. water on the moon 
3. Mars 2030 --> also probably won't happen

Mars: The Red Planet
- Galileo invented the telescope
    - named after the god of war by the Romans
- 4th planet in our solar system
- made up of iron, nickel, potassium, sulfur, magnesium, aluminum, and calcium
Why mars?
- similar to Earth
- Day-night cycle (24.6 hours)
- evidence of past water and life
- same surface area of land 
- has a thin atmosphere
- manageable distance away 

4. Read online textbook, chapter 2 :
- What did you learn? 
  • The Soviet Union launched Sputnik in 1957, the world's first anti-ficial satellite
  • 1958 - U.S created NASA
  • 1961 - John F. Kennedy announced goal: U.S would land a man on the moon before decade's end
  • 1969- Apollo 11 landed the first humans on the moon: Neil Armstrong and Buzz Aldrin
  • women were key members of NASA
    • Katherine Johnson, Dorothy Vaughan, Mary Jackson 
    • NASA refused to support female astronauts 
  • Humans haven't been on the moon in 50 years 
  • Women and people of color played crucial roles
  • Space Stations started in 1971
  • Robotic missions have explored Mars 
  • Rovers: Sojourner, Spirit, Opportunity, Curiosity, Perseverance 
- What was most helpful? I enjoyed the Teacher Talk Portion. I liked how you explained the human side of space exploration and how it is about the people and how diversity played a key role in many historical events.
- What do you need more information on? I would like more information on the logistics of how long it takes to go to the moon and the prep and planning it takes!

5. What questions, concerns, and/or comments do you have? Why hasn't anyone gone to the moon recently? If they started now, how long would it take to go to Mars?

Week 12: Before the Flood

  1. What did you do in lab today? Climate Change  1. What are the primary points in the video? Climate change is not a future problem, it's happening now and affecting millions of people. the documentary showed how burning fossil fuels, deforestation, and industrial farming are major contributors to global warming. Political and economic systems often slow down action, even when solutions already exist. 2. What are the major issues? Not enough people or leaders are taking this issue seriously. Developing countries will suffer the most, even though they contribute the least to the problem. We might reach a point where the damage can't be reversed. 3. What questions do you want us to teach you? What I can personally do to make a difference. Is the world on track to meet the goals from climate agreements?  How can countries switch to renewable energy sources effectively?

Week 6: Geologic Time

   1. What did you do in lab today?   Quiz Review Topics  Shadows If the sun is ______ and I'm at ______ where is my shadow pointing? Moon Phases new moon = no moon  full moon = all moon waxing quarter waning quarter Solstice, equinox  Equinox = equator  Solstice = winter vs summer  summer solstice = sun at cancer winter solstice = sun at capricorn Tropic Lines: Cancer (N), Equator, Capricorn (S) Lifecycle of Stars, Galaxies, Meteor "lifecycle" 3 types of galaxies: Spiral, irregular, elliptical (milky way is spiral)  Andromeda is the galaxy we might collide with stars start as a nebula, then explodes to star, can turn into a nebula or a black hole when a meteor enters earth's atmosphere it becomes a meteorite  Earth Science  Big Bang: 13.7 b.y.a Earth: 4.65 b.y.a EarthView BioInteractive 2.

Week 10: Convection, Plate Boundaries, and Layers of Earth

  1. What did you do in lab today? Why do we have earthquakes & volcanoes not on boundaries? Ancient fault lines At one point Iowa was at the edge of the continent, could've been a fault line Fracking drilling of natural gas and oil  this could have an effect of an earthquake due to stress Convection Currents  Surface currents carry warmer, less dense water from the equator to the poles water from deep currents rise to replace water, leaving in surface currents warm water from surface currents replaces colder, denser water that sinks to the ocean floor coldest water: the poles Warmest water: equator arctic waters come down to equator, heat up, then goes back up Alfred Wegener Because the earth was spinning the continents were moving --> this is what he based it on  not strong enough to bring continents together or apart (was laughed at) Layers of the Earth Crust: outer layer of earth Mantle: convection is happening Core: inner most part of Earth --> very ho...
