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, and only 24 reject climate change
  • There is no data out there that can possibly debunk climate change
  • Even from 1896 climate scientist have been saying there will be global warming
LOWER near water
  • Latitude: Distance from the equator is a key in determining whether a climate is hot or cold
    • Places closer to the poles = colder  temperatures 
    • Places near the equator = warmer temperatures
  • Ocean Currents: temperature of an ocean current affects the temperature of air that passes over it.
  • Wind & Air Masses: air mass is a large volume of air that takes on the climatic conditions of the area where it is formed
  • Elevation: the Higher in Altitude, the Colder in Temperature. As the air rises, it expands because of the lower air pressure. As the air expands, it cools. 
  • Relief: precipitation created when an air mass rises to cross a mountain barrier An adiabatic process is one in which no heat is gained or lost by the system.
  • Near Water: In the summer the water acts like an air conditioner to keep the air temperatures cool
    •  In the winter water acts like a heater to keep the temperatures from getting too cold
    •  Continental Climate (Away from water)
    • Maritime Climate (Close to water)
Glaciers
  • Glaciers are melting and retreating which is insane amount of evidence of global warming
Paris Agreement
  • Unenforceable
  • US led the charge
  • A few years ago US withdrew environmental commitments 
  • International treaty to keep global warming to a limit of 2 degrees
  • Jan 2021 US rejoined



Lecture:

More than 99.9% of studies agree that humans are causing climate change. 

Climate change

  • Climate is the average weather at a given point and time of year over a period of 30 years.
  • Weather can change from day to day, but climate remains constant.
  • If the climate does not remain constant, we call it climate change
  • Significant change depends on the underlying level if climate variability. 
  • If you put more carbon dioxide in the air the molecules will vibrate and warm the atmosphere 
  • Some regions have hot climate and some have cold. 
LOWER near water 
  • Latitude- distance from the equator is a key factor in determining if climate is hot or cold. Places closer to the north or south pole are colder. Places near the equator are warmer. 
  • Ocean Currents- Temperature of ocean currents affect the temperature.0. of air that passes over it. 
  • Wind and Air Masses- An air mass is a large volume if air that takes on the climatic conditions of the area where it is formed. .Wind happens when there is an uneven 
  • Elevation- The higher in altitude the colder in the temperature, as the air rises, it expands because of the lower air pressure. as air rises it expands
  • Relief- precipitation created when an air mass rises to cross a mountain barrier, an adiabatic process is one in which no heat is gained or lost by the system 
  • Near Water- In the summer the water acts like an air conditioning to keep the air temp low. 
Glaciers
  • Melt the north pole and nothing changes, it is like an ice cube in water the volume of the glacier in the water is already accounted for.
  • Continental glaciers melt and run off into the land and could cause potential flooding. Many communities built their towns at the bottom of glaciers with security that the run off will provide them with water to survive. If the glaciers melt they will no longer have water people will die of dehydration and raise sea levels. 
  • There are three glaciers that are getting bigger because they are located in south America that are growing because they are in a specific area where precipitation is increasing, and it is getting colder at the same time. 
  • If the south and north pole melt it will stop the convection currents within the earth, and the whole basic cycle of how nutrients is cycled in the ocean will be disrupted.

Week 9

  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 4: Gravity/Swing

  Week 4 Big Question: Main Takeaways on slide and gravity: Weight is how much gravity is pulling down on an object.  When thinking about how things fall weight matters. But air drag also has a huge effect. a crumpled piece of paper, and a loose crumple of paper fall at different rates but have the same mass. The tight crumpled piece of paper has less air drag than the loose paper.  Air drag can cancel almost all or most of gravity on the loose paper. The heavier an object is the longer it takes to slow down or speed up. Gravity does pull harder on objects with more mass, but adding air drag and the time it takes for heavier things to speed up and slow down cancels the forces and makes it even. A rider who weighs more will finish the slide at the same time as a light rider. Because the time it takes to speed up or slow down an object of greater mass, and air drag cancels out the competition. How can we support play that is exciting and not dangerous? What affects a riders...

Week 7: Solar Systems

-
  Week 7  Lab We began by discussing our homework on misconceptions. We talked about strandmap and the purpose of it, and how we can combat misconceptions. We then as a group created a model of the solar system with playdough. We calculated the numbers to try to ensure that they were to scale for distance and size. It was so interesting and shocking to see how far we had to place each planet. Our group had to go into the TLC to measure the distance and it was so surprising how far they were from each other. This was a great activity to use in the classroom to help children understand the distance between each planet.  This activity made all of the misconceptions of what we learned in elementary school seem crazy. The solar systems we would make in class on hangers were no where near accurate in size, or distance. This activity is a great alternative for children to see the accurate sizes and distances. Especially the distance between the sun and the planets.  The vid...
