1. Bioengineering REVIEW DAY!  Catalyst:  What is gel electrophoresis?  What do restriction enzymes do, and what are they used for?  In GATTACA, what were 3 ways people tested the DNA of in-valids and valids? Write in complete sentences! Don’t talk during the Catalyst!

2. Objectives By the end of today, all SWBAT…  Evaluate the pros and cons of advances in biotechnology  Ace the unit test tomorrow  Kick Stroh’s butt tomorrow

3. Bring it back…  Bioengineering uses science and math to design, produce, and change life  Bio = life  Engineering = using science and math to design, produce, and change machines Genetic engineering Stem cell research Cloning

4. What are the implications?  Stem cells are cells that have the possibility to turn into any type of cell (brain, heart, kidney…)  How could we use this to treat diseases?

5. Issues  Some people have issues with getting stem cells from aborted embryos  However, there is a new technology that is on the horizon… CLONING

6. Cloning  Cloning an organism takes 4 steps…  1) Remove nucleus from an egg  2) Remove nucleus from cell that you want to clone  3) Place nucleus in empty egg  4) Give jolt of electricity to make it divide

7. Cloning  Cloning can be used to produce personalized stem cells.  Cloning can be used to produce sick cells and we can analyze how they get sick.  However, can “we create life just to destroy it?”

8. Free-Response Questions  Tomorrow, the majority of your questions will be free response questions.  You will be asked to think of one positive consequence and one negative consequence for each situation.

9. Rubric 4 pointsStudent makes valid statement AND justifies it with logic 2 pointsStudent makes valid statement without justification 0 pointsResponse is blank or irrelevant

10. What does it mean to justify?  What is one positive consequence of cloning human beings?  Example:  We could clone human stem cells. This is positive because we could use the stem cells to cure diseases, like Alzheimer’s. 4 points!

11. What does it mean to justify?  What is one positive consequence of cloning human beings?  Example:  Cloning would be positive for society because of the stem cells. 2 points!

12. What does it mean to justify?  What is one positive consequence of cloning human beings?  Example:  I wouldn’t have to go to school anymore. 0 points!

13. Let’s judge together…  Mr. Lewis wants to only hire teachers with no genetic diseases. What is one positive consequence?  Example:  No teachers would be absent due to genetic diseases. Since teachers would be at school more, students would learn more. 4 points!

14. Let’s judge together  Mr. Lewis wants to only hire teachers with no genetic diseases. What is one negative consequence?  Example  One negative consequence of Mr. Lewis’ rule is that teachers would be angry. 0 points!

15. Let’s judge together  Mr. Lewis wants to only hire teachers with no genetic diseases. What is one negative consequence?  Example  One negative consequence is that some people who would be great teachers would be kept out of the classroom. 2 points!

16. Let’s Judge together  Mr. Lewis wants to only hire teachers with no genetic diseases. What is one negative consequence?  Example  Mr. Lewis should not discriminate hiring teachers based off genetics because that’s trifling. 0 points!

17.  100 years in the future, the NFL decides that it will only draft players with certain genes for athleticism and strong legs.  What is one positive consequence of this?  What is one negative consequence of this?

18. Rubric 4 pointsStudent makes valid statement AND justifies it with logic 2 pointsStudent makes valid statement without justification 0 pointsResponse is blank or irrelevant

19.  Health insurance companies decide to require each applicant to get a genetic test before getting insurance. Therefore, the insurance companies can pick exactly what insurance a person should get.  What is one positive consequence of this?  What is one negative consequence of this?

20. Rubric 4 pointsStudent makes valid statement AND justifies it with logic 2 pointsStudent makes valid statement without justification 0 pointsResponse is blank or irrelevant

21.  Colleges in the future decide that ACT scores aren’t important. Instead, they use DNA to decide if an applicant is accepted or rejected.  What is one positive consequence of this?  What is one negative consequence of this?

22. Rubric 4 pointsStudent makes valid statement AND justifies it with logic 2 pointsStudent makes valid statement without justification 0 pointsResponse is blank or irrelevant

23.  Some farmers are able to afford to genetically engineer their crops to produce their own pesticides. This way, farmers won’t have to spend money spraying pesticides and the putting chemicals in the soil and groundwater.  What is one positive consequence of this?  What is one negative consequence of this?

24. Rubric 4 pointsStudent makes valid statement AND justifies it with logic 2 pointsStudent makes valid statement without justification 0 pointsResponse is blank or irrelevant

25. Exit Question  A group of scientists figure out how to clone humans and start harvesting stem cells. They decide to clone anyone that asks to be cloned.  What is one positive consequence?  What is one negative consequence? Write in complete sentences! Don’t talk during the Exit Question!
