  1. Science Keys Biology Day 3 Cellular Respiration Arkansas Science Instructional Specialists 2010

  2. Overview • Agenda • Norms • One Day Training • 7 E Learning Cycle • Cellular Respiration • Teacher’s Guide

  3. Summer 2010

  4. Safety • General Safety Information • Material Safety Data Sheets (MSDS) www.MSDSonline.com • Safety Equipment • Goggles

  5. Lab Safety • Lab Safety Rules Online • Jim Kaufman • Founder of the Laboratory Safety Institute • Expert in lab safety • Website: http://www.labsafetyinstitute.org/ • Think! “What is the worst that could go wrong?”

  6. OVERVIEW • Unit time line = 5-6 class periods • Concepts of cellular respiration • Kinesthetic activities • Labs • Literacy connections • Graphic organizers

  7. Cellular Respiration • Arkansas Framework SLEs • MC3.B.5 Compare and contrast cellular respiration and photosynthesis as energy conversion pathways • MC1.B.4 Explain the role of energy in chemical reactions of living systems: activation energy, exergonic reactions, endergonic reactions • MC3.B.1 Compare and contrast the structure and function of mitochondria and chloroplasts

  8. Classroom Time Line • Day 1 • Energy Transfer Demonstration • 3D Model of Cellular Respiration • Magnetic Concept Map • Day 2 • Mitochondria Video • 4 Square • Mitochondria Model • Venn Diagram

  9. Classroom Time Line • Day 3-4 • Fermentation • Jigsaw Activity • Day 5-6 • Pearson Movie • Flap Book

  10. Assessments Open response Concept map Formative assessment Summative assessment

  11. Energy Transfer Engage http://imet.csus.edu/imet1/dave/portfolio/peanut_lab.htm

  12. Energy Transfer Demonstration • Elicit • Is there energy in food? • When burning a food item how much change in water temperature will there be? • Discuss

  13. Cellular Respiration 3D MODEL Click Here • Explore • Construct models to represent the reactants in the equation of cellular respiration. • What is the equation for cellular respiration?

  14. Cellular Respiration 3D MODEL • Explore • Disassemble the reactants and create the products of cellular respiration. • What did you notice about the number of atoms in the products as compared to the reactants?

  15. Cellular Respiration 3D MODEL • Explain • Discuss “Conservation of Matter” • Magnetic Concept Map • Connect respiration to the reactions of photosynthesis. • Relate this to the Carbon Cycle.

  16. Venn Diagram • Evaluate • Complete the Venn Diagram ? What is this?

  17. Mitochondria • Elicit • mitochondria video for elicit.mp4 • 4 square

  18. Mitochondria • Elicit • mitochondria video for elicit.mp4 • 4 square • Engage • mitochondria powerhouses of the cell.mp4

  19. Mitochondrion http://media-2.web.britannica.com/eb-media/89/22489-004-EE9DC4F5.gif

  20. Mitochondrion Outer Membrane-layer of phospholipids Inner Membrane-more permeable than outer membrane Intermembrane space-between the outer and inner membranes Cristae-layers of inner membrane folds that increase surface area. Matrix-site of Kreb’s cycle Ribosome-site of protein synthesis mDNA-DNA found only in mitochondria ATP Synthase-enzyme that makes ATP from ADP

  21. Mitochondrion Matrix- site of the Kreb’s cycle Ribosome- site of protein synthesis mDNA- DNA found only in mitochondria ATP Synthase- enzyme that catalyzes phosphorylation of ADP to ATP.

  22. Mitochondrion • Explore • Construct a mitochondrion model • Explain • Describe the function and structure of a mitochondrion

  23. Chloroplast • Explore Intergrana

  24. Structure of a Chloroplast Membrane - Layers of phospholipids Thylakoid - Flattened interconnected sacs that are stacked like coins Granum - The name given to each stack of thylakoids. Intergranum - Connects the thylakoid Lumen - Cavity or thylakoid space Stroma - Fluid outside the thylakoid that contains DNA and ribosomes

  25. Mitochondria • Evaluate • Venn diagram • Compare and contrast structure and function of the mitochondria and chloroplast.
