–Warm Up: Using The Big Bang: Formation of the Universe data table (below): How soon did protons and neutrons form after the beginning of the universe?

–Plan T.A.I.A. writing response. Students will have 15 minutes to plan with the book open. Then, they will have the remainder of the class period to write a response for the Think About It Again.

à How do astronomers measure how stars and galaxies move? What do these movements tell astronomers about how the Universe formed? How did the solar system form? What is the probability that there are planetary systems beyond our own? How do you know?

–Warm Up: Using your ‘geo words’, write 10 analogies.
Challenge your shoulder partner to complete the analogies.
–Partner: Finish the Understanding & Applying (p. 39) small group check answers with the key.
— Whole group: How Equinox’s Work-Beyond Our Earth http://www.youtube.com/watch?v=CjbgzL2Axok
Draw a diagram of the spring Equinox.
–Whole group: Solar Energy Nuclear Fusion in the Sun http://www.youtube.com/watch?v=pusKlK1L5To write 3things that you learned-2things that are interesting-1question/AHA! Share what you wrote with your shoulder partner.
–Plan T.A.I.A.  turn in planning page before end of class. How do astronomers measure how stars and galaxies move? What do these movements tell astronomers about how the Universe formed? How did the solar system form? What is the probability that there are planetary systems beyond our own? How do you know?

–Warm Up: In your own words, what is the difference between a law and a theory (you may refer to the book p. 38)? Now, create a comic strip that explains the differences between laws and theories.
— Individuals  Checking Up (p. 38; 1-9) Check the key when you finish; after you finish, work on vocabulary

— Partners: Understanding & Applying (p. 39) Small Groups whole group

–Reading Groups: Formation of the Universe, Solar System, AND Planets. Be sure to read the light blue box What is the Difference Between a Law and a Theory (p. 38)?
Individuals  Checking Up (p. 38; 1-9)
