  1. Biology 2011-12 Semester 2

  2. Biology 1/30/12Week of 1/30 to 2/3 • ANNOUNCEMENT: Each entry task will be worth 2 POINTS this semester. Total of 10 points in a typical week. • ASSIGN TABLE LEADERS. 2 Extra Credit points/week EVERYONE AT TABLE has the sheet complete and turned in. • Entry Task – Monday • If you needed to explain photosynthesis to a 3rd grader, what would you say? Please write it out for your entry task • Take out photosynthesis labs and review answers.

  3. Biology 1/31/12 • Entry Task – Tuesday • On a scale of 1 to 4, how well do you think you met these standards? • I can explain how plant cells use photosynthesis to produce their own food. Use the following equation to illustrate how plants rearrange atoms during photosynthesis: 6CO2+6H2O+light energy —> C6H12O6+6O2 • I can explain the importance of photosynthesis for both plants and animals, including humans. • Please also enter your self-assessment on your red sheets.

  4. Act out Photosynthesis • Lab station – plant cell with chloroplasts • One actor as the Sun • Six actors as 6 carbon dioxide molecules (each containing 1 carbon and 2 oxygen atoms) • Six actors as 6 water molecules (each containing 2 hydrogen and 1 oxygen atom) • One person ready to become 1 glucose molecule (containing 6 carbons, 12 hydrogens, 6 oxygen atoms) • Six people ready to become 6 oxygen gas molecules (each will contain 2 oxygen atoms). • AFTER ACTING – sit down and write a reflection – 10 minutes. What happens during photosynthesis? What molecules start the process? What do they change into? What are the products of the process? • If you understand photosynthesis better now, update your red sheets.

  5. Biology 2/1/12 • Entry Task – Wednesday • Read page 228 in the Biology textbook. Please define cellular respiration IN YOUR OWN WORDS. • Get labs out and begin.

  6. Introduce Cellular Respiration • STANDARDS (EALR 4 LS1 ): • I can explain how the process of cellular respiration is similar to the burning of fossil fuels (e.g., both processes involve combustion of carbon-containing compounds to transform chemical energy to a different form of energy). • I can describe the role that enzymes play in the breakdown of food molecules and synthesis of the many different molecules needed for cell structure and function. • I can explain how cells extract and store energy from food molecules.

  7. Cellular Respiration Lab – Day 1 • Choose groups of 5 and sit with them at your desks. • Read through lab. • Write hypothesis. • Create Data Table. • WATCH demonstration of set-up! • Gather materials. Write names on large paper and set all materials on paper on back work table. • You will do the rest of the lab tomorrow.

  8. Biology 2/2/12 • Entry Task – Thursday • Read page 228 and examine the diagrams at the bottom. What is the diagram showing you to help you understand the text? Give information from the diagram. • Finish lab.

  9. Cellular Respiration Lab – Day 2 • Create data table. • WATCH demonstration of set-up! • Gather materials. Write names on large paper and set all materials on paper on back work table. • Conduct steps 1-6 with your group. • Record data. • Clean up. • Rinse all materials carefully in large sink. • Begin answering questions.

  10. Biology 2/3/12 Week of 1/30 to 2/3 • Entry Task – Friday • Explain why the process of cellular respiration is important to biology and life on earth. In your explanation provide details utilizing the chemical equation. • Table Leaders – Check that all sheets are complete – help team finish. Collect all entry task sheets AND PLACE IN PAPERCLIP WITH YOURS ON TOP. • Start and finish lab! All labs DUE MONDAY!!!

  11. Biology 2/6/12Week of 2/6 to 2/10 • DECIDE ON NEW TABLE LEADERS! • Entry Task – Monday • What gas will be created and bubble through the tubes in our yeast and sugar flasks? What process creates that gas? • Conduct lab – quickly, efficiently, carefully. Follow instructions, please

  12. Biology 2/7/12 • Entry Task – Tuesday • Consider your group’s data table. How does the concentration of sugar affect cellular respiration in yeast? In which flask (high or low sugar) was more CO2 produced? • Lab due WEDNESDAY. We will share data and work on questions together TOMORROW!! • TWO Important assignments today to practice for HSPE.

  13. Biology 2/8/12 • Entry Task – Wednesday • Listen as Ms. Maring reads article about cajun crayfish. • Write a summarizing sentence using: • IDENTIFY (who what where) - VERB – FINISH SENTENCE. • Thank you table leaders for all your hard work helping your team!!! • Today we will complete an article summary as practice for HSPE. • We will also learn how our answers are scored and score a person’s answers near us. • PS If you did not finish the text feature assignment from yesterday, please do so today (Cheyenne, Braiden, Tim, TJ, Ryon, Jeremy, Dylan, anyone else???)

  14. Practice for HSPE – Reading 10th grade • Text and Text Features • Summarizing • Scoring using a rubric • Each answer can only get a MAXIMUM of 2 points…but include extra as a safety measure.

  15. Biology 2/9/12 • Entry Task – Thursday • In which kinds of cells does cellular respiration occur? • In which organelles? • Complete article summaries. • Grade another person’s summary using the rubric. • EXTRA TIME? Please take out lab…make sure you have complete data from someone (Example – Briana, Tim, Skyler, Justin, Justine, others???). Begin answering questions…

  16. Biology 2/10/12 • Entry Task – Friday • Describe your effort in science this week…Many of you have been working very hard Congratulate yourselves! • Table Leaders – Check that all sheets are complete – help team finish. Collect all entry task sheets AND PLACE IN PAPERCLIP WITH YOURS ON TOP.

  17. Today’s Work • Short Schedule - 8:00-8:42 • Share data – if your group did not have time for completion on this long lab, please copy another group’s data. Briana’s group’s data on the board…. • Begin questions. Lab will be due end of class Monday. • Next Week – Acting out Cellular Respiration. • Quiz on Photosynthesis and Cellular Respiration.

  18. Biology 2/13/12 Week of 2/13 to 2/17 • Entry Task – Monday • Choose new table leaders, please • Read the text box on page 232 and examine the accompanying graphs. • Answer questions 1, 2 and 3. • Take out cellular respiration with yeast labs. • Complete all questions today and turn in!! • If you have extra time, color code “Flow of Matter and energy in the Biosphere.”

  19. Biology 2/14/12 • Entry Task – Tuesday • Free 2 points for “Saying Something Nice” on Valentine’s Day. Please make this about effort in school or something appropriate… • Share answers to lab and turn in cellular respiration labs.

  20. Act out Cellular Respiration • ENZYMES • C6H12O6 + 6O2  6CO2 + 6H2O and ATP • The hallway is the lungs. • 6 oxygen molecules will enter and be carried by the BLOOD to the cell. • Inside the mitochondria, the glucose molecule will be “burned” with the oxygen. • ENZYMES help. • Rearranging into carbon dioxide, water, and ATP. • 6CO2 is carried away by the blood, to the lungs, to be exhaled. • DURING cellular respiration, the CHEMICAL ENERGY in glucose, is transformed into the energy molecule ATP. • ATP will be used to do the work of the cell, like building DNA, proteins, lipids, transporting vesicles, etc.

  21. Cellular Respiration Reflection • AFTER ACTING – sit down and write a reflection – 10 minutes. • What happens during cellular respiration? What molecules start the process (reactants)? • Where? • What do they change into? What are the products of the process? • How are the lungs and blood involved? • How is energy transformed in the process?

  22. Biology 2/15/12 • Entry Task – Wednesday • On a scale of 1 to 4, how well do you meet the following standard: • I can explain how cells extract and store energy from food molecules. • EALR 4 LS1 • I can explain how the process of cellular respiration is similar to the burning of fossil fuels (e.g., both processes involve combustion of carbon-containing compounds to transform chemical energy to a different form of energy). • EALR 4 LS1 • PLEASE ADD SELF ASSESSMENT TO RED PAGES!

  23. Biology 2/16/12 • Entry Task – Thursday • Read the text on pages 218-219. Examine the timeline. Explain 2 ways the timeline helps you understand the text. Give information from the timeline. • Take out your reflection papers about our modeling of cellular respiration.

What are the products of the process? • How are the lungs and blood involved? • How is energy transformed in the process?

  25. Cycles and Flow of Matter and Energy • Color code the diagram. • Each word color should match the color of the part on the diagram. (Look for the little letters). • REVIEW FOR QUIZ!!
