1. Bioengineering REVIEW DAY!  Objective:  SWBAT ace the unit test tomorrow  Catalyst:  In GATTACA, what were 3 ways people tested the DNA of invalids and valids?  Pick genetic engineering, stem cells, or cloning and describe why you support or oppose the idea of it.

2. Agenda  Catalyst  Writing Short Answer Questions  Practice  Exit Question

3. Bring it back…  What is Bioengineering?  Bio=life  Engineering=using science and math to design, produce, and change machines  Therefore, Bioengineering is using engineering to change life. Examples?

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. How could stem cells help humans?  If we can harvest cells that can turn into any type of cell... There are many potential uses:  Cancer:  Alzheimer’s:  Burn victims: we can implant new “good cells” to grow and remove the “bad cells.” a degenerative brain disease. When old people begin to lose memory, new brain cells could be implanted to replace the dying ones. if someone’s skin gets damaged from a bad burn, the dead skin can be replaced with new skin

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

7. 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

8. 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?”

9. 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.

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

11. What does it mean to justify?  Student must be able to justify why their response is correct…  Example:  Cloning would be positive for society because if we could harvest stem cells, it could cure some of the worst diseases. We are not destroying life, we are saving life. 4 points!

12. What does it mean to justify?  Student must be able to justify why their response is correct…  Example:  Cloning would be positive for society because of the stem cells. 2 points!

13. What does it mean to justify?  Student must be able to justify why their response is correct…  Example:  Cloning would be positive for society because I wouldn’t have to go to school anymore. 0 points!

14. Let’s judge together…  One positive consequence of Ms. Ducros discriminating which teachers can teach at West Jefferson High School would be teachers being absent less and therefore students doing better. 4 points!

15. Let’s judge together  One negative consequence of Ms. Ducros’ regulating which people teach at West Jefferson High School is that teachers would be angry. 0 points!

16. Let’s judge together  One negative consequence of Ms. Ducros’ regulating which people teach at West Jefferson High School is that you may prevent some great teachers from ever reaching the classroom. 2 points!

17. Let’s Judge together  Ms. Ducros should not discriminate hiring teachers based off genetics because that’s trifilin’.

18.  100 years in the future, the NFL decides that it only wants players with certain genes for athleticism and strong legs.  What is one positive consequence of this?  What is one negative consequence of this?  Do you agree/disagree? Why?

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?  Do you agree/disagree?

20.  Pet stores decide that they never want to sell a dog that has thin fur. They screen all dogs and only accept those that have the genes for thick fur.  What is one positive consequence of this?  What is one negative consequence of this?  Do you agree/disagree?

21.  Colleges in the future decided collectively 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?  Do you agree/disagree?

22.  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?  Do you agree or disagree?

23. Exit Question  What do you need to do to be ready for this test tomorrow?  PRACTICE a 4 pointer!  A group of rogue scientists figure out how to clone humans and start harvesting stem cells. They decide to clone anyone that asks to be cloned.
