1 Biology Day 37 Wednesday, November 12 Thursday, November 13, 2014

2 Title: Photo 51 Do-Now 1. Write the FLT 2. What do you think DNA is? 3. Where is DNA found? 4. Draw what you think DNA looks like. 5. It took a long time for scientists to figure out what DNA looked like. Why do you think this took so long?

3 Announcements* Today s*do0now*and*assignment* will*be*collected*separately*from* your*binder*assignments* Project*due*Friday*!*!*!*

4 Planner: Project due! Read 5.1 (weebly) Table of Contents #4 1. Brainstorm/Practice Test 2. Ch. 4 Vocab Review WS 3. Ch. 5 Vocab A 4. Ch. 5 Vocab B

5 Test Review Calculate your test percentages Decide which sections you want to re-take See me before school or at lunch for retakes Remember % = (score received/pts possible) * 100

6 Standard HS-LS 3-1 Students can ask questions to clarify relationships about the role of DNA and chromosomes in coding the instructions for characteristic traits passed from parents to offspring FLT I will be able to identify scientists that contributed to the discovery of the structure of DNA by completing Photo 51 Worksheet.

7 Photo 51 Read over the questions As you watch, do your best to answer the questions If you miss a question, wait until AFTER the video is finished to ask your group members

8

9 Classwork 1. Check your video notes with your group 2. When you re sure your answers are 100%, turn in with your do-now (make sure your name is on both) 3. Work on your project or binder assignments quietly when finished 4. OR " begin reading Ch. 5

10 Noise level 1 Classwork Work on the 4.6 reinforcement and study guide Review for quiz or complete binder assignments

11 Biology Day 38 Thursday, November 13 - Friday, November 14, 2014

12 Video Notes: Cell Cycle 1. Write the FLT 2. While cooking, your friend Bob cuts off part of his finger. In a couple weeks, though, his finger looks back to normal. List the steps his finger would go through to get back to normal. 3. What is cancer, and how is it treated?

17 HS-LS 1-4 Standard Students can use a model to illustrate the role of cellular division and differentiation in producing and maintaining complex organisms FLT I will be able to identify and describe the stages of the cell cycle by completing 5.1 Power Notes

18 Video Notes We will watch two videos Write 8 facts from the videos You may get your facts from one or both videos

21 Notes Protocol Take notes at Noise Level 0 Raise your hand to question/comment Be prepared to pair-share

22 5.1: The Cell Cycle Key idea: Cells have distinct phases of growth, reproduction, and normal functions.

23 Cells die just like everything else # Cells need to DIVIDE in order to produce MORE cells before they die The Cell Cycle

24

25 Eukaryotic cells undergo the cell cycle Cell cycle = pattern of cell growth, DNA replication, & division The Cell Cycle

26 When the cell is growing and carrying out normal activities, it is in interphase. 15. Interphase = G1, S, & G2 The Cell Cycle

27 Eventually, the cells will undergo division. 8. Cell Division The Cell Cycle

28 Eventually, the cells will undergo division. 8. Cell Division The Cell Cycle

29 The Cell Cycle has four main stages: 1. Gap 1 (G 1 ) 3. Synthesis (S) 5. Gap 2 (G 2 ) 7. Mitosis (M) G 1, S, and G 2 are ALL part of interphase! The Cell Cycle

30 Pair-Share-Respond 1. What type of cells undergo the cell cycle? 2. What do we call the part of the cell cycle where the cell is NOT undergoing division? 3. What are the four stages of the cell cycle? 4. Which stage involves cell division?

31

32 Gap 1 (G 1 ) 2. Normal activities & cell growth occur. Organelles replicated. Longest phase.

33 Synthesis (S) 4. Synthesizes (makes a copy of) DNA

34 Gap 2 (G 2 ) 6. Additional growth as cell prepares to divide

35 Cell Division Cell Division includes two parts: 14. Mitosis (copied cell forms) 13. Cytokinesis (cytoplasm divides)

36

37

38

39 Mitosis Mitosis (M) has four stages: prophase, 10. metaphase, 11. anaphase, 12. telophase

40 Add to side: Cell division (mitosis + cytokinesis) creates identical daughter cells with duplicated chromosomes

41 Pair-Share-Respond 1. During which stage does the cell prepare for division? 2. During which stage is DNA copied? 3. Which stage is the longest? 4. What is cytokinesis?

42

43

44 Cells Divide at Different Rates The rate of cell division depends on the type of cell Some cells (neurons) are unlikely to divide)

45

46 Cell Size is Limited Cells must hold organelles & move easily Materials must be able to quickly enter/exit cells Cells want to maximize surface area-tovolume ratio

48 CW Work on 5.1 reinforcement/study guide Binder assignments! Review for quiz

49 Quiz/Test Procedure 1. Clear your desk of everything except a pencil 2. Noise level 0 3. Keep eyes on your own quiz/test at all times 4. Raise your hand to ask a question 5. Flip your quiz over and put your head down when you re finished
