  What did you do in lab?   - We watched a few videos.  - we learned about greenhouse gasses and infrared light.  - we found the little black bead amongst the million of yellow beads.  What did you learn in lecture? - co2 changes, temperature changes - Sources of natural variability: “solar and volcanic forcing are the two dominant natural contributors to global climate change during the Industrial Era.” And there has been NO significant changes, leaving ONLY human causes.  - the earth is a giant convection current  - what is the albedo effect and how does it affect climate? The reflectivity of a surface; how much radiation is reflected vs. absorbed.  - is the albedo effect a positive or negative feedback loop? Positive - albedo effect: this is a feedback cycle affecting the ice caps and glaciers. A cycle of cause and effect that can either be amplifying of conditions or minimizing. - Snowball earth  What effect does this have on the albedo a...

  What did you do in lab? What was the big question? - talked about the Before the Flood movie - talked about coupled inquiry - Phenology : timing of natural events - why is it important to help students learn how to read data?                     - because they will need to be able to read data and create data when they are older and for when they are wanting to learn about these things that are changing.  Create a brief lesson plan outline on how you could introduce the idea of “data” ad reading data in your future classroom?  What did you learn from the Pressbook? What is a greenhouse gas? Certain gases in Earth’s atmosphere are called greenhouse gases. Like a greenhouse, they let sunlight through to reach the surface of Earth and then trap its heat in the atmosphere. The most abundant greenhouse gases are: Carbon dioxide (CO 2) -Carbon dioxide is naturally released from decaying organisms and volcanic eruptio...

  What did you do in lab and what was the big question? - we looked at global climate change pictures from NASA.com  -  100% of scientists believe that climate change is human caused.  - what is the difference between weather and climate? Climate is a 30 year average of weather .  Ex : Weather decides what clothes you wear, climate decides what clothes you buy. If weather is my mood, climate is my personality.                                   City #1                                   City #2                              City #3 Avg. of first 5:  8 days                               ...

  What did you do in lab today? - Went over the sweater article  - Law of Superposition : the rocks that are further down are older.  - Intrusions are younger than every layer they go through.  - sand created through water is polished, smooth, and generally smaller in size. - sand created through glaciers is polished, smooth, and generally irregular in size.  - sand created through wind is opaque, frosted, pitted, and very fine grained.  #6 from lab we thought was sand created through wind because it is smaller/grainy in size.  #11- Oolitic sand- only found in three places on earth, Muscatine being one of them.  - rivers come in different “ages” that are not related to how “old” they are, but the energy they possess.  Young rivers carve down, have lots of energy, and tear apart the land, eroding all that it can due to energy from gravity. They can move material of any size and have similar characteristics: 1. Whitewater 2. Boulders 3. Fast...
