    Assignments:
    Aug. 27-28 Homework:
    • Watch the first four videos below (1. properties of water, 2. Intro to organic molecules, 3. Biomolecules Part 1, and 4. Biomolecules part 2) and take notes in your "unit one note packet". There will most likely be a quiz next class.
     Aug. 29-Sept. 2 Homework:
     
    Sept. 3-4 Homework:
    • Watch the "Tour through the cell" and "structure and function of cell membrane" videos found below
    • Prepare for quiz on Sept. 5   
     Sept. 5-11 Homework:
     
     Lab Design
    Finish designing a lab to test how the shape and size of a cell affects the rate of diffusion.
    Finish designing a lab to model the osmosis of water across a cell membrane.

    Take each of the Questions and objectives below and match them with the Big Idea, Enduring Understandings, and Essential Knowledge they correspond to:
      Essential Questions:
    • Why is carbon the base molecule for life?
    • What are the essential properties of water that makes it possible to support life?
    • What are the chemicals that make up living things and how do simple monomer molecules combine to form complex polymers?
    • How does the form of a molecule relate to its function?
    • How could simple organic molecules form the basis of life? How might chemical evolution occurred on early Earth?
    • How is a cell a self-contained system?
    • What are the components of the cell and how do they work to coordinate cellular homeostasis?
    • How do the properties of the cell membrane relate to the functions of a cell?
      Objectives:
    • Review simple chemistry rules regarding atoms and molecules.
    • Review the properties of water.
    • Review the properties of carbon and discuss the structural flexibility of hydrocarbons.
    • Identify and describe the major organic molecules found in living things.  Identify their uses.
    • Discuss the levels of structure of a protein.
    • Describe the process of dehydration synthesis and hydrolysis.
    • Analyze the statement “form relates to function” as it applies to molecules in living systems.
    • Investigate the hypotheses that explain to origin of life under abiotic conditions on Early Earth.
    • Discuss the historic development of the cell theory.
    • Define homeostasis and apply this definition to a cellular process.
    • Identify and describe the function of the major components of the cell.
    • Describe the fluid mosaic model of the cell membrane and determine how its structure relates to its function and how it is involved in maintenance of homeostasis.
      Activities, Readings and Labs:
    • Read – Campbell Chapters 2-5, 26, and 7 & 8
    • Properties of water lab
    • Cell Anatomy Lab
