STUDY GUIDE FOR TEST 6.P.1.1 WAVES  You will now receive a study guide to complete to help you review for tomorrow’s test!  You will complete this in class…  You will all have 10 minutes to complete this silently and independently at your desk  NO TALKING !

 CHROMEBOOKS FOR THE REMAINDER OF CLASS!  I will dismiss you by rows to grab your chromebook and login  Go to my teacher wiki page  Wait for teacher instructions  Click on lessons and download powerpoint Monday October 19

AGENDA  Review video - How sound travels through different materials with notes  Seismic waves introduction, video, and cut and sort activity

INTRODUCTION VIDEO  B942-C291-4CF4-BF81-CA9A C B942-C291-4CF4-BF81-CA9A C  Discovery Education login  User name: CMS student ID # _cms  Password: CMS student ID #

NOTES ON SOUND PLEASE WRITE THIS IN YOUR NOTEBOOK  Sound is a mechanical wave (requires a medium to travel)  Sound travels as a longitudinal wave ( also known as compressional wave) when molecules collide

WRITE THIS IN YOUR NOTEBOOK! NO MEDIUM = NO SOUND!!!! This is why there is no sound in outer space --- it’s a vacuum Light travels faster than sound Why we see lightening first then we hear thunder second

SPEED OF SOUND WRITE THIS IN YOUR NOTEBOOK! Sound travels Fastest in solids Slowest in gases

SPEED OF SOUND  ed.org/EducationResources/HighSchool/Sound/speedinmaterials.htm ed.org/EducationResources/HighSchool/Sound/speedinmaterials.htm  Click on play animation  Answer the following questions in your notebook  What happens when you change the material through which the sound travels?  Why do you think it is faster?

SEISMIC WAVES…  IN THE FOLLOWING SLIDES YOU WILL BE READING AN ARTICLE AND RECORDING INFORMATION FOR QUESTIONS, WATCHING ANIMATIONS AND COMPLETING A CUT AND SORT

READING GETTING TO KNOW SEISMIC WAVES  46AA-8B52-5E1DC3E2D AA-8B52-5E1DC3E2D932  Click on the link above and read the article  When you are done please answer the following questions in your notebook IN COMPLETE SENTENCES!  1. Is a seismic wave the same thing as an earthquake?  2. Is it true that seismic waves can’t cause any damage when they occur in the ocean?  3. Are there ways for scientists to study seismic waves?

SEISMIC WAVE SIMULATION  isualizations/es1002/es1002page01.cfm?chapter_no=visualization isualizations/es1002/es1002page01.cfm?chapter_no=visualization  Click on play for the P wave then the S wave

GRAPHIC ORGANIZER  You will now work on your Earthquakes and Seismic Waves Graphic Organizer  Please cut out the pictures  You will need to figure out which wave is a P-wave, S-wave, and surface wave. You will also need to figure out the speed, location, and other information for each wave  P Wave = picture showing compressions and dilations in undisturbed medium (compression)  S Wave = picture showing amplitude and wavelength (transverse)  Surface Wave = picture showing both wave types together

GRAPHIC ORGANIZER  You will now work on your Earthquakes and Seismic Waves Graphic Organizer  Please cut out the boxes  You will need to figure out which wave is a P-wave, S-wave, and surface wave. You will also need to figure out the speed, location, and other information for each wave
