    4/9A & 4/10B: Meet in the library. Students will be randomly assigned to groups to research articles about their controversial topic using the controversial topic database. Use this link to get there quickly: Issues and Controversies Database  They will have 20 minutes to each read a different article on their topic and record the author, title, pros, cons, and their own opinion of their topic and article. Then the group will present their consensus  as a group to the teacher when called up.  If the database isn't helpful with your topic here are additional links to news articles: Discover Magazine            New York Times biotech articles

    Topics are as follows: (The colored dot on your note sheet correspond to your topic)

    Designer Babies, Organ Farming, Germ Warfare (dark green), Human Cloning (yellow), Stem Cell Research, GMO Foods, Genetically Modified Animals (brown), Animal Testing in Biotechnology, and Prosthetics.

     Students will also be assigned a Biotech webquest worksheet to complete by the end of the period.  Here is the link to the webquest: http://mr-hester.weebly.com/biotech-webquest.html .

    4/11A & 4/12B

    Then we will take biotechnology notes from the Biotechnology ppt.  Students will learn how restriction enzymes work to cut DNA into pieces that can create a DNA Fingerprint to solve crimes or confirm family relationships.  

    4/13A & 4/16B

    We watched: Making Babies Genetically Correct then answered the questions below:

       1) Do you think it is okay to genetically alter babies? Why or why not? What conditions are okay or not okay? (i.e. checking or curing disease, selecting all of the traits like hair and eye color, etc.)
       2) Take notes on each of the families so you know their story: Jack's family (the Freedman Family), Molly's family (the Nash Family), and Family X (last name not given).
       3) Is it okay to terminate a pregnancy if the baby will be sick? What conditions would make it okay? Not okay?
       4) What's going on with the Freedmans? With the Nash Family?
       5) Is a 25% chance of having a baby with a bad gene too high? What would you do in the situation? Adopt? Try again anyway?
       6) Is it okay to have a baby to save your other child? Do you or your parents have the right to your body/cells?
       7) Is this "playing God"? Or do you think God gave people the ability to develop this technology so we should use it?
       8) Do you think it is worth it to do hormone treatments if it could cause the mother to get cancer or possibly die? 
       9) Is it okay to experiment on embryos? Why or why not? What kinds of limitations should there be?
       10)  Would you want to have children if you knew you were going to die before you got to watch them grow up?
       11)  Do you think that we could get to a point in our society where only certain babies will be allowed to be born? Would that be right?          (Consider China's ban on having more than one child and many parents only keeping the boys).
    4/17A & 4/18B
    We will model genetic transformation by doing the paper plasmid activity. And determined the babies that were switched at birth. Chapter 9 vocabulary chart is due at the end of the period next class.
    4/19A & 4/20B - we will answer questions from the following video and turn in chapter 9 vocabulary chart
    Decade of the Human Genome Video Link - try this link first as it is full-screen
    A Decade of the Human Genome Video Link - only try if 1st link won't open
    4/23A & 4/34B - Test and folder/notebook check are next class - students are to complete the study guide questions

    Questions for the study guide are:

    Answer the following on a separate sheet:

    1) Explain how genes can be manipulated.

    2) Explain 2 specific uses of genetic engineering?

    3)  What is a plasmid?

    4) How are plasmids used in bacterial transformation?  

    5) What do restriction enzymes do?

    6) How are restriction enzymes used to make a DNA fingerprint?

    7) What does ligase do?

    8) What is it about DNA that enables us to create recombinant DNA (DNA from more than one organism)?         

    9) What does GMO mean?  What are some uses of the GM plants? Why do we create GM animals?

    10)  Explain how biotechnology and products made with biotechnology can improve human life. Give at least 3 specific examples.

    11)  What ethical questions or issues arise because of the use of biotechnology? Give and 3 examples (the name of the ethical issue and explain why it’s an issue for people).

    12) Understand how these terms are related: recombinant DNA, gene of interest, transgenic, ligase, restriction enzymes, plasmid, and sticky ends.

    13) What are 2 uses for DNA fingerprints? How do you read that DNA fingerprint (are you looking for an exact match or half and half?)

    Also, in partners, students will complete the DNA Evidence Evaluation WS to practice how to make and interpret a DNA fingerprint.
