Tests!!!! eccentricity

Congratulations to Gabby for doing the Solar\Lunar eclipse extra credit.

Geo: review for similar tri-angles, ratio/proportion, perimeter's test tomorrow.

Eng: keep reviewing for book one (ch. 1-11) of TKMB; test tomorrow.

Global: keep studying for imperialism test on Friday.

ES: eccentricity lab tomorrow in class. Look at the cover of the esrt for the formula. Zero is closest to a circle for an eccentric path of a sate lite and closer to 1 (one) the path is more elliptical like the shape of a football.
Study the diagram, note an e of 0 makes a circular path, and as the eccentricity number increase toward 1 (one) ie: .77, the path becomes flatter and longer. Click the diagram to be teleported to a flash animation on planet eccentricity.
