b. 
Astronomy or Astrology?
     I would like you to do some basic research on the difference between astronomy and astrology. Many people confuse the two terms, or use them interchangeably.  After you have read about these two terms, I would like you to consider and answer the following questions:
    
    Why is astronomy considererd a science, while astrology isn't?
     If astrology is not a science, then why do so many people believe
     in it?       Do you?     If so, then the question becomes, why do you?


c.
Microclimate:
     We live at a time when humans are unintentionally changing the climate of their planet.  We also change the climate of our homes, but do so that we are more comfortable.

       I would like you to identify and discuss at least four ways in which your family controls the microclimate of your home.

d. 
There's seaweed in my what??
     Seaweed is an ingredient that is often found in cosmetics, candy bars, soups, salad dressings, ice cream, yogurt and jelly.  It is not listed as seaweed in the ingredients list, however. (They wouldn't want to make you sick.)
     Carrageenan is a generic term for compounds extracted from species of red algae.  Carrageenanas are used in stabilizing and gelling foods, cosmetics, pharmaceuticals, and industrial products.  From brown algae come alginates.  They make water based products thicker, creamier, and more stable over extreme differences in temperature, ph, and time.  Beta Carotene, a natural pigment derived from green algae, is used as a yellow-orange food coloring.

     I want you to find and list 10 products that contain seaweed.  Be sure to give the brand, name of the product, and what was on the label.  For two of the items you must bring in the label.
