Reviewed what we did on Friday (Listening Skills)
Handed back Room Scavenger Hunt papers and Quizzes on Class Policies

Students who did not take the quiz took it while I handed back papers

Paired students for Astrogeniosity Pre-Test
Students said something nice to partner, then took test. Must stay in seat and must talk ONLY to partner.

Students handed in tests.

Content Objectives:
Students will will able to
. Describe the motions of the Earth and Moon using words and pictures

Asked students to go to page 6 in their notebooks, write date, and write content objectives. In Table on Contents on Page 1, students wrote page 6, Motions of Earth and Moon and right hand rule.

Started with calender showing divisions into year, month, day.
Gave astronomical definitions of year, month, day and drew corresponding pictures
Also gave definitions of:
axis: line drawn through the object
rotate: spin or turn
orbit: go around an axis not part of the object

planet <--plane all planets go about the Sun in the same direction and in about the same plane.

Drew pictures for radius, diameter, circumference, area

Explained right hand rule poem

Thumbs up for Santa, right
Fingers curl, spin day to night
These same fingers also show
The way around the Sun we go!!

Students practiced poem

Talked about how theories change
flat Earth --> spherical Earth Asked for evidence (don't fall off Earth, when ships sailing away you see sails go out of view last, different stars depending on latitude, shape of Earth on Moon during Lunar eclipse)

Sun and planets around Earth --> Sun at center of solar system

Discussed when is best time to see shooting stars
