Week 14: Science of Climate Change

  What did you do in lab today? We looked into how much carbon dioxide is in the atmosphere. We learned how they figured out how much carbon dioxide was in the atmosphere. It has been increasing over time, leading to an increase in temperature.  PhET Simulation  CH4  Visible photons do not get stopped Not all infrared photons get stopped, but some of them do and then get “spit” back out  CO2 The visible photons just go right through it and do not get stopped Not all infrared photons get stopped, but some of them do and then get “spit” back out  H2O The visible photons just go right through it and do not get stopped Not all infrared photons get stopped, but some of them do and then get “spit” back out  N2 The visible photons and infrared photons do not get stopped and go right through  O2 The visible photons and infrared photons do not get stopped and go right through  Greenhouse ga s: a gas that absorbs and re-emits infrared light  CH4 C...

Week 13: Glaciers, Paris, and Sea Level

  What did you do in lab today? Today in lab, we got into groups and researched different parts of climate change. There were 3 groups, and they looked into precipitation, temperature, and ag and plant life. My group looked into how ag and plant life are affected by climate change.  What was the big question? How is climate change changing the world around us?  What did you learn in Thursday’s discussion? If you change the way you teach, all students can succeed  Glacier retreat  Sea level rise  Paris agreement An international treaty on climate change that was created to limit global warming to a change of 2 degrees Celsius (some goals are 1.5c °C)  - we have already warmed 1 degree Celsius since pre-industrial times  Includes 195 nations that meet together every 5 years to discuss progress toward goals  Adopted on December 12, 2015  Read chapter 13 of the textbook. What did you learn? Iowa's temperature is rising, and there will be mor...

Week 12: Albedo and Greenhouse Gases

Image
  What did you do in lab today? What are the primary points in the video? How fast climate change is really happening We have knocked down whole ecosystems in the ocean   Most of the US economy is made up of fossil fuels  Other countries are doing way more with solar energy than we are  Climate change is not a matter of if but when  What are the major issues? Fossil fuels  Greenland is melting  By 2040, you will be able to sail over the North Pole (actually happened last year)  Places around the equator will become unlivable  What questions do you want us to teach you? How can we help?  How do renewable energy sources work compared to fossil fuels? What was the big question? How is climate change affecting Iowa?  What did you learn in Thursday’s discussion? Climate is a 30-year average of weather  6 variables that control climate  Latitude   Distance from the equator Closer to the poles → cold temperature Closer ...

Week 11: Climate Change

  What did you do in lab today? We talked about the water cycle.  Air pressure: how much weight the air is pressing down on Earth  What was the big question? What is weather?   What did you learn in Thursday’s discussion? We did not have lecture this week because of the exam.  Read chapter 11 of the textbook. What did you learn? Weather: what is happening now  Warm front: the boundary where a warmer air mass is moving in to replace a colder air mass  Cold front: the boundary where a cooler air mass is moving in to replace a warmer air mass  Low-pressure systems are associated with more volatile weather conditions, such as clouds, rain, and wind  In a high-pressure system, the weather is typically sunny and clear  Wind is caused when Earth’s surface is heated unevenly by the sun  What was the most helpful? I liked how this chapter covered things not discussed in lab. This was helpful to get a better picture and understanding relating...
