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?

 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)

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

 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.

 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

 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 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

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

Highlands, and maria, and craters…oh my!

 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.

 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.

 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.

 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

 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

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

 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%

 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 ( ° F) Really Hot! Really Cold!

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

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

 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

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

 Rilles  Valley-like structures found in the maria

 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

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

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

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

1. Read “History of the Moon” on pages 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)

 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?

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.
