Students will model a BNL developed non-toxic technique for removal of toxic metals from soil. By using iron as a model for a toxic metal, students will quantify the amount of iron in a soil sample before and after removing the iron.
Vocabulary: chelation, photodegradation, remediation, spectrophotometer, standard curve
|Core Document||Physical Setting/Chemistry Core Curriculum|
|Performance Indicators||KI 1 Scientific Inquiry:|
“The central purpose of scientific inquiry is to develop explanations of natural phenomenon in a continuing, creative process.”
KI 2 Scientific Inquiry:
“Beyond the use of reasoning and consensus, scientific inquiry involves the testing of proposed explanations involving the use of conventional techniques and procedures and usually requiring considerable ingenuity.”
KI 2, Mathematical Analysis:
“Deductive and inductive reasoning are used to reach mathematical conclusions.”
|Major Understandings||S 1.1 Scientific Inquiry:|
“Elaborate on basic scientific and personal explanations of natural phenomenon, and develop extended visual models and mathematical formulations to represent thinking.”
S2.1 Scientific Inquiry:
“Devise ways of making observations to test proposed explanations.
“Use deductive reasoning to construct and evaluate conjectures and arguments, recognizing that patterns and relationships in mathematics assist them in arriving at these conjectures and arguments.
|Performance Indicators||PI 3.1 Physical Setting:|
“Explain the properties of materials in terms of the arrangement and properties of the atoms that compose them.”
PI 3.2 Physical Setting:
“Use atomic and molecular models to explain common chemical reactions.”
|Major Understandings||MU 3.1cc, dd Physical Setting:|
