 Ch.1                           The Nature of Life

• 1-1 What is Science
• 1-2 How Scientists Work p.9 Theories p.14-15 (2.2.2)
•  Parts of a Scientific Investigation

1. How to write a hypothesis (2.1.2)
2. Manipulated Variable
3. Responding Variable
4. Controlled Variables
5. Experimental Control
6. Validity
7. Reliability

• Practice Sampel labs (2.1.2)
• 1-3 Studying Life
• 1-4 Tools and Procedures

Ch. 2                         The Chemistry of Life (Organic Compounds

                                  and Enzymes)

• 2-3 Carbon Compounds
• Lipids
• Nucleic Acids  
  • Ch.12 DNA and RNA
    • 12-1 DNA pg. 291-294     

   Describe how proteins control life functions (the protein myosin and actin interact to cause muscular contraction; the protein hemoglobin carries oxygen in some organisms).

• Proteins
  • Enzymes  
    • Salivary amylase lab
    • Catalase Lab
    • Toothpick Activity
• Carbohydrates

Ch. 7                         Cell Structure and Function

• 7-1 Life is Cellular
  • Observing Different types of Cells

1.3.8 Understand how organisms, including cells, use matter and energy to sustain life and that these processes are complex, integrated and regulated.

• 7-2 Cell Structure
  • Cells- Structure and Function 
  • Organelles- a review of function 
    • 3-D Cell Project
    • The cell as a City

  Describe cellular structures that allow cells to extract and use energy from food, eliminate wastes, and respond to the environment.  (Every cell is covered by a membrane that controls what goes into and out of the cell).

• 7-3 Movement through the membrane
  • Cell membrane- selectively permeable barrier
  •  Diffusion- Demo: starch/iodine lab
  •  Osmosis- celery osmosis
  •  Microscope Orientation
  •  Onion/cheek cell osmosis (microscope lab)
  •  Active and passive transport
