New PBIS Textbook – Ever-Changing Earth

I will need a volunteer from each row to go back and get enough copies of our new textbook for everyone

What is the Structure of Earth?Open your textbook and turn to page EE59

QuestionDo you think earth is covered by one solid

unbroken piece or do you think that there are breaks in the covering of the earth?

What are some clues?

What is the Structure of Earth?Turn now to page EE 60

Let’s think about what we just readBy studying pictures we can get

clues as to whether earth’s surface is continuous or broken.

You may also be able to infer what moves when there are earthquakes and volcanic eruptions.

Observe these pictures…Turn to pages EE 61 –EE 62 to view various picturesWorking with your table partner, you will answer

questions at the bottom of EE 60 in your interactive notebooks

I will assign each table a specific group of pictures to study; you and your table partner will then answer the questions

Group #1 = Mount St. Helens Eruption 1980Group #2 = Guatemalan Earthquake 1976Group #3 = Birth of the Isle of Surtsey 1963Does anyone have any questions about this activity?10 minutes! GO!

3 Corners....Go to the part of the room where other groups of students

studied the same picture as you.Discuss each group’s answers to the questions, compare

ideas, and determine what questions you may still have Group #1 = meet at the TV Mount St. Helens Eruption

1980Group #2 = at the pencil sharpener Guatemalan

Earthquake 1976Group #3 = at the glass cabinet Birth of the Isle of

Surtsey 1963You have 3 minutes.. GO…

Poster Creation with your table partner (30 minutes)

• 1. Title • 2. Before/After picture. What changed?• 3.How do you think a volcano erupts or

how does an earthquake occur.• 4. Other stuff you’d like to know about

earthquakes or volcanoes.• 5. How does the picture you studied help

you to think about if the earth is one continuous structure or one that is made up of many pieces.

Let’s share our findingsPoster presentations……
