Wednes-Day 2
Bio- HW: due Monday, outline text section 39.1
We began our discussion of the Immune System by looking at causes of infectious, hereditary, and environmental/behavioral diseases.
We defined the term, pathogen, which is any agent that causes an infectious disease: virus, bacterium, fungus, protist, etc.
We discussed several means by which pathogens can spread infection throughout a population and
how some pathogens are more virulent or less fragile than others.
We also began to discuss the human organism's three lines of defense against pathogens.
Chem 7/8- we continued our unit on Organic Chemistry by looking at the various HOMOLOGOUS SERIES of hydrocarbons: the alkanes (all single bonds, saturated with H) , alkenes (contain ONE double bond), and alkynes (contain ONE triple bond; "alkYne-trYple"). We looked at the GENERAL FORMULA of each of the homologous series of hydrocarbons and noted that, for each additional multiple bond, TWO fewer H's are in the formula.
We also practiced naming each successive member of a homologous series and the possible isomers for a given chemical formula.
We also began another series of organic compounds, alkyl halides, each of which contains one or more halogen atoms covalently bonded to the carbon chain. We saw that the naming rules for alkyl halides are similar to those for naming alkanes with side chains.
We then did an activity in which we built models of all possible isomers of C6H14.
Chem 9- we continued our unit on Organic Chemistry by looking at the various HOMOLOGOUS SERIES of hydrocarbons: the alkanes (all single bonds, saturated with H) , alkenes (contain ONE double bond), and alkynes (contain ONE triple bond; "alkYne-trYple").
