UNIT 2: GEOLOGIC EVENTS

7th Grade IB Science

U2: Geologic Events

U2: AHA Connections

Bell Work Set up AHA Connections pages on pgs. 22-

23 of your notebook. The title is: U2: AHA Connections. NO DATE Record the following question in the light

bulb: How do people cope with things beyond their

control? Add these 3 questions in to the same area

of pgs. 22-23: What evidence supports continental drift? Why did scientists question the continental drift

hypothesis? Which coastlines might once have been joined

together?

U2:Trigger Activity Sept. 6, 2011 Objective: You will create 2 puzzles (one with

small pieces and one with large pieces).

Put the title and date on pgs. 24-25 in your notebook.

Using 2 pieces of notebook paper, draw a simple picture.

Cut one picture into large puzzle pieces. Cut the other picture into small puzzle

pieces.

U2:Trigger Activity Sept. 6, 2011 Write a hypothesis in your notebook on

pg. 25 about which puzzle will go back together with less trouble. “If I put together the puzzle with…then I will be able to get all the pieces to fit.”

Put pieces together. Write a statement after your hypothesis

to explain if your hypothesis was supported or not and why.

U2:Trigger Activity Sept. 6, 2011 Homework:

Look at a map of the globe and answer the following question on pg. 24 of your notebook: Which coastlines might once have been joined together?

Answer in a STATEMENT not a paragraph. What evidence from today’s activity helped

you answer this question?

How old is the Atlantic Ocean, 9-14-11

Copy the mini lab from pg. 197 onto pg. 31 in your notebook.

Choose a partner. Work through the lab together. Analyze and Conclude about the age of the

Atlantic

Types of Mountains 10-4 (NB44-45)

Folded Mountains Examples: Rocky Mountains, The Alps Created by compression at convergent boundarieshttp://www.youtube.com/watch?v=jVyBsUgD7Gk&feature=results_main&playnext=1&list=PL957C73D6B68723E3

Fault-Block Mountains Example: Basin and Range Province in western and

southwestern U.S. Created by tension at divergent boundaries – crust

pulls apart to form a fault and large blocks of crust slide up or down

Types of Mountains 10-4 (NB44-45)

Uplifted Mountains Example: Sierra Nevada Mountains

Volcanic Mountains Examples: Mt. St. Helens, Hawaiian Islands Formed by sitting over a hotspot or by

subduction of an oceanic platehttp://www.youtube.com/watch?v=Bf4iJvrAv-M

Transform Faults Occurs when plates at a divergent

boundary slide horizontally to each other, perpendicular to the ridge/rift

Fault Zones Occur when plates slide past each other,

shearing and causing smaller faults to form perpendicular to the main fault

As you read through chapter 9, write questions on sticky notes (front table and back counter).

Imagine yourself teaching either earthquakes or volcanoes. What do you think is important for students to know? (Use this to guide your question writing).

Do you have any project ideas for this chapter that could help answer the BIG IDEA question (see your AHA Connections pages for Geologic Events)?

Types of Faults 10-17-11

Strike-Slip Fault Forms at a Transform boundary (like the

boundary between the Pacific Plate and the North American Plate, which has formed the San Andreas Fault Line)

Types of Faults 10-17-11

Normal Fault Forms at a divergent boundary when two

plates (or blocks of crust) are pulled apart and one slides down the other

http://www.youtube.com/watch?v=tJDnfT1pqhQ&NR=1

What type landform can a normal fault cause?

Types of Faults 10-17-11

Reverse Fault Forms at a convergent plate boundary

when two plates compress and one plate gets pushed up slightly

Which type of fault caused the Japan 2011 earthquake 80 miles off the east coast of the islands? Why do you think that?

Comparing Earthquakes 10-18-11 How are responses of people in other

nations different than and similar to the responses of people in our nation?
