Wednesday, January 2 nd Entry Task 1.Have you ever been in an earthquake? 2.Have you seen damage from an earthquake on the news? 3.What are some things that can happen because of earthquakes (damage-wise) Schedule: Deadliest Earthquakes Video Homework: Read 7.1 Objective: I can understand the effects of earthquakes

Thursday and Friday January 3-4 Mrs. Guttormsen was out and there was a sub There were no entry tasks or objectives for these days. Thursday, The 7.1 RSG and Chapter 7 vocabulary were assigned—Choose a strategy and do for all words in Chapter 7.

Monday, January 7 th Entry Task Write down the entire sentence and fill in the blank with the correct term 1.All Earthquakes occur along _________. 2.The force exerted when an object pushes, pulls, or presses against another object is called ________. 3.Most faults are located along __________ ____________. Schedule: 7.1–Types of Faults Notes 7.2 RSG Homework: Read 7.3 Objective: I can understand that earthquakes occur along faults

Types of Faults

Rocks Move Along Faults Fault: –Fracture, or break, in Earth’s lithosphere, where blocks of rock move past each other At some parts of a fault, the rock slides slowly or constantly. At others it sticks or locks together. –Rock bends as stress is put on it (the force exerted when an object presses on, pulls on, or pushes against another object.)

Earthquake –shaking of the ground caused by the sudden movement of large blocks of rock along a fault –can occur when there is a sudden release of stress in the lithosphere. Release of stress occurs when the rocks break free from being stuck Strength of an earthquake depends on –The amount of stress built up –The distance the rocks move along the fault

The rocks that move Most faults are along tectonic plate boundaries –Most earthquakes occur here The rocks that move during an earthquake are smaller than tectonic plates A small percentage of earthquakes occur along faults within plates –Stress along a plate boundary can cause the rocks to break and move along weak areas in the middle of the plate.

Types of faults Faults are classified base on how they move –How they move is determined by the kind of stress that they are under. More than one type of fault may be present along the same boundary.

Normal Fault The block of rock above the fault plane slides down relative to the other block Occurs when stress pulls the rocks apart Earthquakes are common near boundaries where tectonic plates are moving apart –The Great Rift Valley of Africa.

Reverse Fault The block of rock above the fault plane moves up relative to the other block Occurs when stress presses rocks together Occurs near collision- zone boundaries between plates

Strike Slip Faults Blocks of rock move sideways on either side of the fault plane. Occurs when stress pushed rocks horizontally Happens when plates scrape past each other

Tuesday, January 8 th Entry Task Answer the following questions full sentences, IQIA. 1.List the 3 types of faults and briefly explain each. 2.Describe the relationships among the focus, epicenter and seismic waves during an earthquake. 3.Explain two ways earthquake damage can be reduced. Schedule: Lab- Earthquake Safe Structures Homework: None Objective: I can understand how structures are built to withstand most earthquakes. Please have on Desk: 7.2 RSG

Wednesday, January 9 th Entry Task Get your building and make sure you sketch it down in your lab packet Schedule: Lab- Earthquake Safe Structures Objective: I can understand how structures are built to withstand most earthquakes. Homework 7.3 RSG

Thursday, January 10 th Entry Task Get your structure on your desk, ready to test. You may make any last minute changes if need be. Schedule: Lab- Earthquake Safe Structures finish Homework: Complete Lab Packet 7.3 RSG Objective: I can understand how structures are built to withstand most earthquakes.

Friday, January 11 th Entry Task Decide if the following statements are true. If they are write them down as is. If they are not, correct them. 1.The epicenter is the point underground where rocks first begin to move. 2.Secondary waves move faster than primary waves. 3.Three circles, each drawn around a different seismic station, meet at the epicenter of an earthquake. Schedule: Seismic Waves Pre-Lab Homework Set up a graph to record your data in. Make sure to follow all instructions on “how to write a lab report” worksheet Objective: I can understand how energy travels in waves Please Have on Desk: Earthquake Structure lab packet

The purpose of this experiment is to determine which type of earthquake wave: P (pull-and- push) or S (side-to-side) travels at a faster rate.The purpose of this experiment is to determine which type of earthquake wave: P (pull-and- push) or S (side-to-side) travels at a faster rate.

If…Then…Because… 1.The P-wave (pull-and-push) will travel at a faster rate. 2.The S-wave (side-to-side) will travel at a faster rate.

1.Collect your materials. 2.Lay the piece of construction paper on the floor vertically - this will be your guide for knowing how far to move the spring. 3.Stretch out the spring 5 meters by having 2 people hold the ends of it.

4.Have one person pull-and-push one end of the spring so it sends a wave back and forth through the spring (record how long it takes for the wave to travel). 5.Repeat step 4 for two additional trials and calculate the average speed of the P-wave.

6. Lay the piece of construction paper on the floor horizontally. 7.Stretch out the spring 5 meters by having 2 people hold the ends of it. 8.Have one person move one end of the spring side-to-side so it sends a wave back and forth through the spring (record how long it takes for the wave to travel).

9.Repeat step 8 for two additional trials and calculate the average speed of the S-wave. 10.Clean up!
