Designed to provide students with an introduction to chemical principles as they apply to important issues in everyday life. The American Chemical Society program Chemistry in Context serves as the basis. The laboratory experience emphasizes the scientific method and is designed to reinforce the topics from the lecture. Students make real world measurements as part of investigations of their environment and the applications of chemistry to their lives. Designed for students who have had no or limited high school chemistry. Fulfills general education natural science requirement.
An introduction to chemistry. Designed for students who had no or limited high school chemistry. sDescriptive chemistry and stoichiometry will be emphasized. The laboratory will introduce the student to the chemical laboratory with emphasis on the handling of equipment and good laboratory practices.
The American Chemical Society program “Chemistry in Context” is designed to present chemical principles on a “need to know” basis as part of a discussion of environmental issues facing society. This approach is allows the students to better see how these principles apply to their wowourld. This approach also provides an opportunity for the students to develop their critical thinking skills and presents the chance for the development of the ability to assess the risks and benefits as each societal issue is discussed, The goal of this presentation is the development of informed citizens that are better able to make informed decisions regarding technical and environmental issues throughout the rest of their lives.
The content of this course relates to standards of the National Council for Accreditation of Teacher Education (NCATE) and the Interstate New Teacher Assessment and Support Consortium (INTASC) Standards. The course addresses Unit Standard One: Subject Matter -
"The teacher understands the central concepts, tools of inquiry, and structures of the discipline(s) he or she teaches and can create learning experiences that make these aspects of subject matter meaningful for students."
