  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.
