(Remember; you don't have to write down today's notes. We're just getting things up-to-speed for this school year.)
I. Current Events: California fires.
A. The city of Pacifica woke to ash covering cars and homes as wildfires, started by last week's lightning, merged and grew.
B. The California fire season - usually August through November - has been getting longer because of climate change.
ASIDE: Look up the Oakland Hills fire or 1991. A warm, off-shore breeze and dry conditions caused a huge fire storm in the Bay Area.
II. Observation skills and science: Two scientists that we'll learn about this school year are Darwin and Fleming … Both used OBSERVATION SKILLS to change the history of science.
A. Darwin: For his observations aboard the HMS Beagle.
B. Fleming: For his observations that led to the wide-spread use of penicillin.
ASIDE: When you see words or phrases CAPITALIZED please look them up. Be sure to define these KEY TERMS.
III. Observation practice: Locate a convenient object outside. (Tree, house, pole, you, etc.).
A. Note the time and date and mark the length of the shadow.
B. Predict: When you return at the exact same time of day will the shadow be longer, shorter, or will it not have changed?
