Leonardo da Vinci
Read and take notes.  Keep your notes simple.  This might be a good time to go back to where  I give you the rubric for taking notes in the very beginning.

Follow any links at Beyond Books for information about Leonardo da Vinci and also check out these links. Both Worlds.   The next links are a few drawings that represent his sensitivity and scientific eye.   Sensitivity   and his  Scientific    Eye.

Those are 3 separate links the last one showing da Vinci's drawing of a flying maching or what appears to be the beginning of a  helicopter.  And this last link is a timeline of   HIS LIFE.  The last link has many options but look at his life and then if you're curious look at the other liinks.
