1. 1. Take your manila folder, a Catalyst Sheet, and a small piece of blank paper (by Catalyst Sheets) to your desk. 2. On your Catalyst Sheet, answer the following:  How do Earth’s movements affect our concept of time including days, seasons, and years?

2.  Day  1 day = 1 rotation of Earth (24 hours)  Season  Based on Earth’s revolution around the sun  Changes because of Earth’s tilted axis ▪ 23.5 ° from vertical  Year  1 solar year = 1 revolution around sun (~365 days)

3.  Catalyst  Opening/Objective  Mini-Lesson: Moon Features  Table-Partner Work: Formation Theories  Closing  Exit Ticket  Homework Completion Time!

4.  Welcome to your final quarter!  Let’s make this your most successful quarter yet!  Astronomy Books  Don’t forget to ALWAYS bring these to class!  If you haven’t gotten one, please see me after class.

5.  Calendar Homework  Due TODAY  Turn-in (INBOX!) at the end of class  If you need a copy (excused absence last class, etc.) ▪ Check the “Extra Copies” folder in the black bin ▪ Assignment is also posted online

6.  By the end of class, CWBAT briefly review the beginnings of space exploration, properly identify features of the Moon’s surface, and will create a foldable analyzing the theories of how the moon formed.  CCSS.ELA-Literacy.RST.11-12.4 Determine the meaning of symbols, key terms, and other domain- specific words and phrases as they are used in a specific scientific or technical context relevant togrades 11–12 texts and topics. CCSS.ELA-Literacy.RST.11-12.4

7.  Take out your notebooks and a writing instrument.  Remember: The most important pieces of information are in red/blue, underlined, bolded, or in italics.

8. Highlands, and maria, and craters…oh my!

9.  For many years all we had were telescopic observations.  Check-In: What are the two types of visible light telescopes?  Reflective telescopes and refractive telescopes  Most of our current knowledge comes from space probes and astronauts.

10.  Sputnik I  Launched in 1957 by the Soviet Union  This began the “Space Race” between the Soviet Union and the United States. ▪ Competition for supremacy in space exploration.

11.  On the small piece of paper given to you, answer the following:  Who was the first human in space?  (Be sure to put your name at the top!)  45 seconds  Place in basket as I come around.

13.  Yuri A. Gagarin  Soviet cosmonaut ▪ What is the difference between a cosmonaut and an astronaut? ▪ Nationality ▪ Astronaut: United States ▪ Cosmonauts: Soviet Union  Went into space in 1961

14.  Though the Soviet Union put the first human in space, the United States won the race to the Moon.  Apollo 11  July 20, 1969  Buzz Aldrin and Neil Armstrong land on the Moon

15.  The lunar surface is very different from the surface of Earth.  Any examples you can think of?

16.  The surface of the Moon is quite dark, despite being so bright in our night sky.  This is due to its small albedo.  The amount of sunlight an object’s surface reflects.  Moon’s albedo: 7%  Earth’s albedo: 31%

17.  No atmosphere  So what?  The amount of sunlight absorbed by the surface of the Moon contributes to its extreme temperature differences.  Sunlight  127 ° C (260.6 ° F)  No sunlight  -173 ° C (-279.4 ° F) Really Hot! Really Cold!

18.  Very different from Earth  No erosion (minus that caused by recent impacts)  Why? ▪ No atmosphere ▪ No water

19.  Highlands  Light in color  Mountainous  Heavily covered with craters  Maria (singular, mare)  Dark, smooth plains  ~3 km lower in elevation than highlands

20.  Impact craters  All craters on the Moon are impact craters  Caused by objects from space crashing into the Moon’s surface  Ejecta  The material blasted out during impacts which falls back to the surface

21.  Rays  Long trails of ejecta radiating out from a crater

22.  Rilles  Valley-like structures found in the maria

23.  Hold up the number of fingers that corresponds with the correct answer.  Which area of the Moon is known for its numerous craters? 1. Highlands 2. Maria 3. Albedo

24.  Which area of the Moon is known for it’s numerous craters? 1. Highlands 2. Maria 3. Albedo

25.  Which area of the Moon is known for being very smooth with few craters? 1. Highlands 2. Maria 3. Albedo

26.  Which area of the Moon is known for being very smooth with few craters? 1. Highlands 2. Maria 3. Albedo

27. 1. Read “History of the Moon” on pages 755-757 in the Earth Science Books. 1. Create a foldable about the three major theories regarding the formation of the Moon.  You must include: ▪ The name of each theory ▪ A brief description of it in your OWN words ▪ Why it is commonly rejected or accepted  You may work with your table partner, but every person needs to have their own sheet!  Feel free to add pictures! Description Accepted or Rejected and Why? (Name 1)(Name 2)(Name 3)

28.  By the end of class, CWBAT briefly review the beginnings of space exploration, properly identify features of the Moon’s surface, and will create a foldable analyzing the theories of how the moon formed.  Thumbs-Up/Thumbs-Down?

29. 1. On your Catalyst Sheet, answer the following:  List at least 3 features of the Moon’s surface and briefly describe each one. 2. Place your completed Catalyst Sheets in the INBOX. 3. Take a Homework Sheet from near the black bin and get started.
