Presentation Transcript

  1. Biology Semester 2 2012-13

  2. 1/28/13 • Entry Task • What are the 4 main kinds of biological molecules? • Which elements are most common in those? • Notes on Carbon and Nitrogen Cycles • Extra Time? Read about cycles of matter and energy pages 41-49

  3. Biological Macromolecules • 1. carbohydrates – think “sugar” • 2. lipids – think “fats” • 3. proteins – think “lots of different kinds…hair and skin and hormones are made of these” • 4. nucleic acid – think “genetic material like DNA” • Most common elements: C, H, O, N

  4. 1/29/13 • Entry Task • Using arrows and words (flow chart) show a possible cycle for carbon starting and ending with the atmosphere. • Finish notes on Nitrogen Cycle. • Start Energy and Matter mini-posters.

  5. Mini-posters: Cycles of Carbon, Nitrogen and Energy • MATTER: • Choose and draw a plant and its herbivore. • Add arrows to show the cycle of CARBON from the atmosphere to the plant (photosynthesis) to the animal (cellular respiration) and back to the atmosphere. • You may use the molecular formulas“CO2” carbon dioxide and “C6H12O6” glucose • Add arrows to show the cycle of NITROGEN from the atmosphere to nitrogen-fixing bacteria in soil, into the plants and animals and back to soil (waste) or back to the atmosphere (by denitrifying bacteria). • ENERGY: • Draw the sun. • Add arrows to show the flow of ENERGY from radiant energy to chemical energy stored in glucose during photosynthesis. • Add more arrows to show the herbivore eating and converting that chemical energy to the energy of ATP and losing energy as heat

  6. 1/30/13 • Entry Task • Explain how energy and matter are different.

  7. Energy Flows and Matter Cycles

  8. 1/31/13 • Entry Task • Trace the energy flow from the sun to your lunch to the basketball game. • HINT: energy forms you may use: nuclear, radiant, chemical (food or ATP), motion, heat • Complete Matter and Energy Project. • Extra Time? Add color and details!!

  9. 2/1/13 • Entry Task • Say Something Nice • Please turn in your entry task sheets! • Study Guide

  15. 2/8/13 • Entry Task • Say Something NicePlease turn in your entry task sheets.

  16. Today’s work • Read the first paragraph of “The Cell Cycle” on page 246. What are some causes and effects of the cell cycle? • Please list one cause and effect for the entry task and a total of 3 on the worksheet. • Read pages 246-249. • Take notes! • Complete #2 and #4 on page 247.

  17. Today’s Work • Watch the cell cycle video/animation. • On your notes page – answer the 5 questions after the video. • Please turn in your work

  18. 2/13/13 • Entry Task • Is the diagram on page 249 showing you multiple cells or a single cell undergoing changes? Explain! • ANSWER: Single cell undergoing changes during the cell cycle. Starts with interphase (regular cell growth) and ends with cytokinesis (cytoplasm getting cut). Mitosis (nucleus splitting) is four steps in the middle

  19. 2/14/13 • Entry Task • List and briefly describe what happens during the 3 stages of the cell cycle. • Interactive animation of mitosis • Watch cell division LIVE

  20. Tuesday 2/19/13 • Entry Task • Both mitosis and cytokinesis are involved in cell division. What’s the difference? • Review rubric. Choose partner. • Start models. • STANDARD: I can describe and model the process of mitosis, in which one cell divides, producing two cells, each with copies of paired chromosomes from the original cell.(EALR 4 LS1)

  21. 2/20/13 • Entry Task • List here your key for these parts to your model: • Nuclear membrane • chromosomes – (total 2 pairs) • chromatids • centromere • spindle • centriole • cell membrane • SEATING CHART!!

  22. Before we start the project… • Review recent QUIZZES! • Complete a reflection if you would like a better score… • MANDATORY reflections for scores of 15 or less! • Remember, to get points back, you must explain: • A. What went wrong? B. What is now more clear? C. The correct answer.

  23. 2/21/13 • Entry Task • Copy this timeline: • Tuesday Feb 19th– choose parts and write key; assemble parts • Wednesday Feb 20th– sketch one cell becoming 2 cells on large paper “game board; begin writing instructions • Thursday and Friday February 21st and 22nd- complete instructions; underline words, practice with own model, make sure instructions are complete and would be “user friendly” for another group • Monday February 25th– ALL MODELS DUE!! Trade and evaluate another group’s model.

  24. 2/22/13 • Entry Task • Say Something Nice • Please turn in your entry task sheets!

  25. 2/25/13 • Entry Task • Compare the number of chromosomes in the daughter cells to the number of chromosomes in the mother cell. • ANSWER: The daughter cells should end up with the exact number of chromosomes as the parent cell!!!

  26. Today’s Work • Finish Cell Division Models: • “Game Board” – sketch of all stages of cell division on which parts of model can be moved • INSTRUCTIONS – how to move the pieces of your model through the cell cycle. ALL VOCABULARY UNDERLINED. • YOUR MODEL – Common objects to represent the parts of the cell - include a written key. • Finished early? Start geranium root cell division! Back table…watch video first… • http://www.youtube.com/watch?v=Qgq9CFopd4c

  29. 2/27/13 • Entry Task • How do scientific ideas change over time? What influences the ideas?

  30. Take Notes! • You will be making a timeline from the information in this movie. • NOTES: • WHO - people, • WHAT - contributionsto scientific ideasAND political issues/ gender constraints of the era • WHERE - countrywhere they conducted their work, • WHEN - YEAR(s) of effort • WHY – why was this discovery important?

  31. 2/28/13 • Entry Task • What is a TIMELINE?

  32. Discuss Answers • A timeline is a graphic representation of the passage of time as a line. Either vertical like facebook or horizontal… • EXAMPLE • http://1.bp.blogspot.com/-zr2Mh-uoWfg/T6BQf69mDLI/AAAAAAAACmk/l_QQlVJ-sis/s1600/Timeline_Inventions.jpg • Often, past on the left…current on the right. • Remember the spaces on the timeline should be even. For example if you want to span 200 years over 10 inches, every inch would be 20 years.
