Stamps: important for binder checks. Homework = SUCCESS

6. Homework CFU (1 min) Question #1 – How many chromosomes did you receive from each parent? Question #2 – Why is it important that chromosomes undergo replication to form sister chromatids?

7. Homework CFU (1 min) Question #3 – How many cells result from Meiosis I? Indicate the number of chromosomes (n or 2n) in each of the cells and whether or not the chromosomes contain sister chromatids. Question #4 - How many cells result from Meiosis II? Indicate the number of chromosomes (n or 2n) in Meiosis II and whether or not the chromosomes contain sister chromatids.

8. Box Today’s Objectives (2 min) 2.1.A (Meiosis) ▫I can describe each phase of mitosis and how it is an early step in sexual reproduction in which pairs of chromosomes separate and segregate randomly during cell division to produce gametes containing one chromosome of each type. 2.1.B (Fertilization) ▫I can describe how new combinations of alleles may be generated in a zygote through the fusion of male and female gametes.

9. Hook – Meiosis Matching Competition (5 min) Match pictures to labels You may use your notes! Pairs at tables versus each other. ▫(3 people? Pair vs Individual) ▫(2 people? Individual vs Individual) Winners get the starbursts :D

10. Investigation Before Explanation (5 min) Pairs work together Definitions ▫Sexual Reproduction  Two organisms (male and female), unique offspring ▫Asexual Reproduction  One organism, identical offspring, quicer Who reproduces using sex? Put each organism into a pile: sexual or asexual How’d you do? Flip over

11. Teacher Notes – Fertilization (3 min) Sex = Variation Fertilization: ▫Sperm + Ovum = Zygote  Sperm = male gamete  Ovum = female gamete  Zygote = first cell of human Example. Smell = Attraction (Immune System Variation = Stronger Children)

12. Student Practice – Fertilization (3 min) Write down in a way that you can remember the question!! 1.Gamete is a __________ cell. 2.Haploid human cell = __ chromosomes. Example is a _________. 3.A diploid human cell = __ chromosomes. Example is a ________.

13. Teacher Notes – Fertilization (more depth in next homework) (3 min) n=23 egg sperm n=23 2n=46 zygote

14. Student Practice – Fertilization (3 min) 1.A gamete contains 3 chromosomes: a)The haploid number is ___. b)The diploid number is ___. 2.A zygote contains 8 chromosomes: a)The haploid number is ___. b)The diploid number is ___.

15. Teacher Notes = Spermatogenesis (4 min) Start = primary spermatocyte. Meiosis I  Secondary spermatocytes. Meiosis II  spermatids. Mature to sperm cells

16. Student Practice – Spermatogenesis (4 min) 1.Spermatogenesis makes __ sperm. 2.A sperm has ___ chromosomes so it is a ______ cell. 3.After Meiosis I. Each cell has (n / 2n) chromosomes and they (do / do not) have sister chromatids. 4.After Meiosis II. Each cell has (n / 2n) chromosomes and they (do / do not) have sister chromatids

17. Teacher Notes – Oogenesis (4 min) Start = primary oocyte Meiosis I  1 secondary oocyte and 1 st polar body Meiosis II  1 ovum and 3 polar bodies **Note: 1 st polar body splits = 2 polar bodies. Secondary oocyte splits = one ovum + one polar body.

18. Student Practice – Oogenesis (4 min) 1.Oogenesis makes __ ovum. 2.Oogenesis makes __ polar bodies. 3.An ovum has ___ chromosomes so it is a ______ cell.

19. Check for Understanding (1 min) How are you feeling? (1 through 10) ▫Circle at bottom of page ▫Show me (I will provide additional help during the lecture activity)

20. Lecture Activity (10 min) Putting it all together! Meiosis, Spermatogenesis, Oogenesis, Fertilization ▫Partner #1: Meiosis, Spermatogenesis, Fertilization ▫Partner #2: Meiosis, Oogenesis, Fertilization Include for all cells: “n” or “2n”, “yes sc” or “no sc” Include & label all vocab in box (plus some) You must be able to do this for your exam.

21. Project – Entry Event (5 min) http://www.youtube.com/watch?v=ys4FEFphRYE

22. Project – Trial by Child (2 min) Genetics and Human Development Pairs = mother and father (different perspectives) “Egg” baby - Negative treatment results in CPS fine

23. Project: Deliverable #1 – Digital Scrapbook (4 min) Posts on digital portfolio. ▫8 sentences. ▫All eight stages: pregnancy to college. ▫Each does 1 post per stage (16 total): father or mother perspective. ▫Include “Life Events” that occur. Photos on digital portfolio. ▫6 photos (infancy to college) Each parent does 3 of the stages. ▫Photoshop or drawn. ▫Characteristics determined throughout genetics unit. ▫Unique and balanced: beautiful and flawed. Budget. ▫As a couple, track budget from pregnancy to college. ▫Include positive/negative “Life Events” that occur.

24. Project – Trial by Child (1 min) Child Protective Services ▫Negligent behavior towards “child” = a fine.  Da Vinci teachers will be monitoring your behavior.  Parents not with child, child abandoned, child mistreated = $$$

25. Project: Deliverable #2 – PSA and Informational Pamphlet (3 min) Create a 5 minute PSA. Post on YouTube, link to DP. Pamphlet will accompany it and will contain: ▫Teenage Pregnancy Info, Risks, Prevention, Resources, and Options Presented and handed out to other classes on February 4 th – 5 th (odd, even)

26. Don’t Panic (1 min) You will have work time to do these. However, I will give you suggestions for when you should have each post, each photo, the budget, the PSA, and the informational pamphlet finished and posted to your digital portfolio.

27. Project Activity (10 min) Partners - On “Project Activity Sheet” ▫Choose father and mother ▫Choose date you discovered pregnancy (2012) ▫Choose birthday - Add 8 mth 2 wks to 9 mth 2 wks Label egg (first and last name) ▫You have the same child, but to experience responsibility better, both of you have an “egg child”

Budget (5 min) Add Budget to Binder. ▫Table of Contents Extra Material  Budget and Brochure_________page 43 Assumptions: ▫You as a couple start having saved 40$ ▫Part time job: 8$/hour after taxes  Parent #1 - 5 hours/weekdays, 10 hours/weekends.  Parent #2 - 5 hours/Friday,Saturday,Sunday ▫Yearly Salary = $24,960 + $40 Saving = $25,000
