science 2 week 13


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

How do we know that the Goldfinch is in danger in Iowa? 

  • whats happening in Iowa
    • average temp increacted by 0.2F over last 30 years 
    • Iowa is getting wetter 
    • more rainfall April, may, and june 
    • 4-6 inches per rainfall
  • path forward 
    • agriculture is a big part of solution 
      • removing air pollution through land protection
        • carbon sequestration - help maintain praries and stop interupting nautral cycle of carbon 
      • preventing pollution of air and water 
        • conservation can help absorb greenhouse gases 
        • protect land long-term by helping plains and the soil 
      • providing habitat for wildlife
        • protexting wildlife homes so they can freely live is important river corridors or large tracts 
      • building resilient communities 
        • protect native ecosysyemsd by keeping praries clear so they can absorb water and help it flow to rivers and streams

The second part of class my groups goal was to look at data from percipitation. 

Iowa is experiencing climate change through an increase in percipation especially rainfall. 

The current average is around 13 inches for spring state-wide average percipiatation 

Whereas snowfall is much less, only an average of 4.5 inches since 2012

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

During lecutre, we disscused that climate is over 30 years and not just about temperature, it can be about rainfall. 

distance from equator is a key factor in determining wheter a climate is hot or cold

Ocean currents: 

temp of ocean current affects the temperature of air that passes over it (ex: San Diego - next to warm body of water, that is why temp is so regular and stable) 

Iowa weather comes from Canadian Rockies, warm/rainy air comes from south

wind & air masses 

- an air mass is a large volume of air that takes on the climate conditions 

elevation: 

- the higher alltitude, the colder in temperature

- as the air rises, it expands becuase of the lower air 


Relief: 

- percipitation 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 

- ascending air cools adiabatically to dew point, water vapor condenses, rain shadow area, descending air warms adiabatically 

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) 


Evidence of Climate Change: 

- glacier 



Answer questions about the weekly textbook reading:

What did you learn?

The book provided more proof that climate change is happening in iowa - percipitation and drought 

notced a lot more rainfall, hotter temps, impact on agriculture, habitat changes 

I also learned that Iowa has a Flood center, it was created to monitor flood risk and to inform the public

I also learned that Hancher & Voxman building had to be rebuild and moved to a different location becuase of a bad flood 

What was most helpful?

The LO.W.E.R. Near Water acronym helped me remember the factors to determine whter an area has a hot or cold climate. 

Lattitude : near the equator have warmer temps, near the north and south poles have colder temps 

Ocean Currents : temp of ocean current affects temp of the air that passes over it 

Wind and Aire massesair masses take on the climate conditions of the area, wind moves moves air masses to a new area 

Elevation : higher altitudes tend to be cooler, lower tends to be warmer 

Relief: air mass rises to pass over topography like mountaions, it exapnds and cools, causes percipitation 

What do you need more information on?

More information about droughts would be helpful in Iowa. In lecuture and lab we payed closer attention to increase in percipitation. 

What questions/concerns/comments do you have?

Will percipitation continute to increase if it gets warmer? Or will droughts become more apparent?

week 3 science 2

The big question addressed in lab, and a description of what you did. We addressed how to interperet motion graphs. The big question was what affects a rider's speed down a slide?  When testing this question, there are different variables to consider/test like slide material, steepness, initial push, weight, temp, wet/dry slide, running start... etc.  Does the weight of a rider affect the speed as they go down the slide?  A description of what you learned in Thursday's lecture In lecuture, we learned about acceleration=change in velocity/time acceleration often gets confused with speed, however, it is different  a question we looked into was WHY do riders accelerate as they slide?  Accelerate in 3 different ways Forces have a magnitude (size) and a direction  Friction depends on... - types of surfaces  - how hard the surfaces are pushed togehter Answer questions about the weekly textbook reading:  What did you learn?  I learned that even...

week 13

  What did you learn this week? This week we learned that density has a role in if an object will sink or float. It depends on the weight in grams as well. If an object is greater than 1gram per mL it will sink.  We discovered this through our dice activity also while revisiting the coca-cola activity. I also learned that salt water is more dense than freshwater. Which parts did you find clear and which were confusing? I still am a little confused as to how one of the coke cans floated. However, I do understand that they are made up of carbonation and one can had more sugar than the other. Therefore, that could be a factor.  What are new or remaining questions?  What objects/matierals are guarenteed to either float or sink?

week 14

  What did you learn this week? We learned about heat and conduction. We made a flip book demonstrating why liquid atoms move faster when heated rather than cooled. Water particles move faster when heat increases. Ice also melts faster on metal than wood because the particles are more tightly packed.  How can you apply what you've learned to your teaching in the future? Using the anology of playing pool helps connect the resoning for slow particles and fast particles moving. Fast partcle hits slow particle.  What are new or remaining questions?  how does kinetic energy come into play when thinking about assesing the simulation?
