                 technology systems.
      1. Students discuss emerging technology resources (e.g., podcasting, webcasting, compressed
          video delivery, online file sharing, graphing calculators, global positioning software).
      3. Students understand the importance of both the predictable and unpredictable impacts of
      6. Students understand that access to online learning increases educational and workplace

Michigan High School Content Expectations Connections:

    B4.2 DNA, RNA, and Protein Synthesis

    B4.2h – Recognize that genetic engineering techniques provide great potential and

    B4.r2i – Explain how recombinant DNA technology allows scientists to analyze the
            structure and function of genes. (recommended)

    B4.r5x Recombinant DNA
            Recombinant DNA technology allows scientist in the laboratory to combine the genes
            from different sources, sometimes different species, into a single DNA molecule. This
            manipulation of genes using bacterial plasmids has been used for many practical
            purposes including the mass production of chemicals and drugs. (recommended)

UDL Connections:
          -Notes and lecture will be presented via the following:

All presentations will be presented using a LCD projector which allows large
print and color to be displayed. This allows all students to see the material
                  *Power point presentation
                        -including pictures and animations

                       *Elmo: modified overhead projector which allows for teacher
                             to write as material is presented.

                               -The material can be displayed using different colors.

                               -Material can be presented in a very large font this way
                                as well.

                       *Human Genome Project:
                            -web site information can be set up in the text reader
                       *The Paper Plasmid Lab:
                             -can be set up in the text reader. This will assist
                              students in the directions of the lab

Teacher Reflection and Notes:

This lesson takes a relatively difficult concept to grasp and provides a number of useful ways for
students to get their hands on it. The use of computers for both information disseminating and
gathering is used. A paper, scissor lab is used to allow students the time to cut, paste, think and see
what is happening.
