Catalyst
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?
Catalyst Answers
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)

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
Objective
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.
Mini-Lesson
Take out your notebooks and a writing instrument. Remember: The most important pieces
of information are in red/blue, underlined, bolded, or in italics.
The Moon’s FeaturesHighlands, and maria, and craters…oh my!
Learning About the Moon 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.
First Satellite
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.
Extra Credit Opportunity
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.
Guesses?
And the Winner Is…
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
Reaching the Moon
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
So What Did They See?
The lunar surface is very different from the surface of Earth. Any examples you
can think of?
The Lunar Surface
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%
The Lunar Surface: Temperature 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!
Lunar Surface: Physical Features
Very different from Earth No erosion (minus that
caused by recent impacts)
Why?▪ No atmosphere▪ No water
Features of the Moon
Highlands Light in color Mountainous Heavily covered with
craters Maria (singular,
mare) Dark, smooth plains ~3 km lower in
elevation than highlands
Features of the Moon
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
Features of the Moon
Rays Long trails of
ejecta radiating out from a crater
Features of the Moon
Rilles Valley-like
structures found in the maria

Creative Study: Formation Theories
1. Read “History of the Moon” on pages 755-757 in the Earth Science Books.
2. 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!

Closing
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.
