Teacher Guide

     A. Identify Questions and Concepts the Guide Scientific  Investigations      

     1.      Formulate a testable hypothesis based on literary research and previous knowledge

2.      Identify and select experimental variables (independent and dependent) and controlled conditions

     B. Design and Construct Investigations

           1.      Design a scientific investigation based on the major concepts in the area being studied

3.      Identify technologies that could enhance the collection of data

4.      Identify possible sources of error inherent in an experimental design

9.      Organize and display data in useable and efficient formats, such as tables, graphs, maps, and cross sections

10.  Draw conclusions based on qualitative and quantitative data

11.  Discuss the impact of sources of error on experimental results

12.  Communicate and defend the scientific thinking that resulted in conclusion.

      C. Use Technology and Mathematics to Improve Investigations and Communications

           1.      Select and use technologies to enhance the precision and accuracy of data collection, analysis and display         

2.      Discriminate between data that may be valid or anomalous

      D. Formulate and revise Scientific Explanations and Models Using Logic and Evidence

      1. Construct experimental explanations or models through discussion, debate, logic, and experimental evidence

2.      Develop explanations and models that eliminate bias and demonstrate the use of ethical principles

3.      Revise explanations or models after review

      E. Recognize and Analyze Alternative Explanations and models

1.      Compare current scientific models with experimental results

2.      Select and defend, based on scientific criteria, the most plausible explanation or model

 III. Earth Science

A. Energy in the Earth System

3.      Heating of the Earths surface and atmosphere by the sun drives convection within the  atmosphere.     

a.       Analyze the effects of atmospheric convection, atmospheric dust and cloud   cover, rotation of the Earth, revolution of  the Earth, and tilt of the Earths rotational  axis on global climates and seasons                  

b.      Explain the factors that affect geographic variations in climate including distribution of land and water, physiographic (geologic) features, and latitudes effects

c.       Relate the transfer of heat energy to the patterns of wind belts

d.      Compare and contrast the formation of high- and low-pressure systems, the formation of fronts, and the movement of weather systems across the surface of the Earth
