2.  Compare and contrast the composition of the atmosphere at different elevations.
3.  Describe the atmosphere as a mixture of gases.
4.  Describe the origins of pollution in the atmosphere, geosphere, and hydrosphere, (car exhaust, industrial emissions, acid rain and natural sources), and how pollution impacts habitats, climatic change, threatens or endangers species.
E.FE.M.1 / E.FE.07.11 / E.FE.07.12 / E.ES.07.42


Today in Class:

  1.  Students completed the Quiz #1 The Water Cycle and Weather.

2.  Next, you were given a graph paper and a direction sheet to label the layers of the atmosphere.  Your goal was to create a graph of the layers of the atmosphere, so you could use this to: compare and contrast the atmospheric layers, evaluate and analyze the temperature trends in the layers and identify various objects (natural and man-made) in each layer of the atmosphere.  Most students completed about 3/4 of their graph.  You will finish these tomorrow.

Students referred to their text, p. 86-89 and the graphs below as you were completing your graph.


Homework:  1.  Please have your parent sign your permission slip for the Invasive Species Trip.  

2.  Some students may choose to work on their Atmospheric Layers graph  for 10-15 minutes if you did not complete the majority of the graph.
