Biology Story Time

The city of San Fransico has just passed a law that will prohibit large grocery chains and pharmecies from using any plastic bags.  Other cities have also passed such laws, some outlawing styrofoam as well. 

Look up the environmental impact of plastics and polystyrene products.    

1.  Goggle this:  plastics and polystyrene recycling? 

2.  What are your thoughts about having a law restricting the use of plastics? 

3.  Would you ask your family to switch to using paper bags at the grocery store - why or why not?  

4.  Why did I title this article, “OIL … what is it good for?”

Our second test for this 2nd quarter is coming up this week.  The test will cover the topics of water chemistry and biochemistry.  We did a lab on the pH scale and we’ve covered the structure of an atom … how to determine it’s structure from its atomic number and mass.  The 4 macromolecules covered on the test will be:  carbohydrates, lipids, proteins, and nucleic acids.  There have been 3 homework assignments to review the topics, we will be making a foldable, and the material being tested is found in Chapter 6 of the text book.
