  • Content area/major concepts: I chose this paper as the next in the module because it puts the sample collection and statistical analysis into practice. Also, it uses a flame AAS which is instrument that the students will use in lab. It also uses a similar method of sample preparation with paint samples for lead analysis to the one used in lab.
    
    Concepts/Content Reviewed: Environmental sample preparation, data analysis, lead contamination, and statistical analysis.
  • Methods or technology used to obtain data: Sample collection, error analysis, and flame atomic absorption spectroscopy.
  • How the CREATE strategy was used:
  • Biggest teaching challenge: Complicated data sets in tables, difficult statistically analysis.
• • Article: Miller-Ihli, N. J. Trace Element Determinations in Foods and Biological Samples Using Inductively Coupled Plasma Atomic Emission Spectrometry and Flame Atomic Absorption Spectrometry. Journal of Agriculture and Food Chemistry 1996, 44, 2675-2679.
  • Content area/major concepts: I chose this paper as the next in the module because it also uses Flame AAS and introduces GFAAS and ICP-AES which are three of the four instruments used in lab. It also has data from some of the elements students will examine in lab.
    
    Concepts/Content Reviewed: Environmental sample preparation, elemental food composition data, data analysis, and statistical analysis.
  • Methods or technology used to obtain data: Sample collection/preparation, error analysis, and flame atomic absorption spectroscopy, introduction to graphite furnace atomic absorption spectroscopy, inductively coupled plasma atomic emission spectroscopy.
  • How the CREATE strategy was used:
  • Biggest teaching challenge: Complicated data sets in tables, difficult statistically analysis.
• • Article: El-Ghawi, U. M. The Level of Trace Elements in Tripoli City Groundwater. Instrumentation Science and Technology 2005, 33, 609-617.
  • Content area/major concepts: I chose this paper as the next in the module because it uses AAS and ICP as well as IC, the last instrument used in lab . It also has data from most of the elements and inorganic ions that students will examine in lab.
    
    Concepts/Content Reviewed: Environmental sample preparation, groundwater data, data analysis, and statistical analysis.
  • Methods or technology used to obtain data: Sample collection/preparation, error analysis, AAS, ICP, and IC.
  • How the CREATE strategy was used:
  • Biggest teaching challenge: : Not enough information given for complete understanding
• • Article: Article
  • Content area/major concepts:
  • Methods or technology used to obtain data:
  • How the CREATE strategy was used:
  • Biggest teaching challenge:
• • Article: Grady, D. Unexpected Dangers Found in Low Levels of Lead. New York Times 1996, C9.
  • Content area/major concepts: I chose this news article because it talks about dangers of low levels of lead which is of great interest for an environmental prospective. It is also to show how news articles do not have all the information and the main source must be located.
    
    
  • Methods or technology used to obtain data: OSHA standards, sample collection.
  • How the CREATE strategy was used:
  • Biggest teaching challenge: Not enough information given for complete understanding
• • Article: Cheng, Y.; Schwartz, J.; Sparrow, D.; Aro, A.; Weiss, S. T.; Hu, H. Bone Lead and Blood Lead Levels in Relation to Baseline Blood Pressure and Prospective Development of Hypertension. American Journal of Epidemiology 2001, 153, 164-171.
  • Content area/major concepts: I chose this paper as the next in the module because it uses a new instrument and one we have previously covered. Also it highlights the dangers of even low level exposure. It also shows the dramatic difference between what a news article might claim and what is actually studied in research.
    
    Concepts/Content Reviewed: Hypertension, lead contamination, blood and bone sample preparation.
  • Methods or technology used to obtain data: K-shell x-ray fluorescence and atomic absorption spectroscopy.
  • How the CREATE strategy was used:
  • Biggest teaching challenge: Complicated data sets in tables, difficult statistically analysis.
• • Article: Wolstenholme, J.; Hessler, W. Low level, long exposure to lead linked to depression, anxiety in women. Environmental Health News,
