1. Monday November 2, 2015 Science

2. Warm Up.. Bring your notebook, pencil, agenda to your desk Complete Monday’s warm up now – do not work ahead then review NOTES for TEST! YOU ARE QUIET, WORKING WHEN THE BELL RINGS

3. Today’s Agenda… Kahoot Review Students will take their Post Test 6.P.1.2 Visible Light Students will take a Pre Test 6.P.1.3 Sound We will review the standard and read aloud the unpacked standard, writing down any words we do not know Tuesday – Vocabulary Foldable for Sound

4. Kahoot Review We will review before our test on Visible Light I will give candy to the top 5 finishers Good Luck!

5. Chromebooks…. I will dismiss you by rows to get your chromebooks Once you are back at your seat, login In a search box type Kahoot it Select the site and wait for the pin to join the game

6. Summative Assessment Today You will take a 15 question summative (post- test) today on Visible Light This test includes all the information we covered over this last week related to Light Take your time and try your best! You will record your answers on a bubble sheet Please write POST TEST on bubble sheet

7. Procedures for Testing Remember you will receive 2 folders Sit these folders up to make your office space Once you are finished, place your test and answer bubble sheet inside your folder You will be given 25 minutes to complete the test ( if you finish early, you may read, draw or just sit quietly) Remember NO TALKING!!!

8. Formative Assessment Today You will take a 15 question formative (pre- test) today on Sound This information will be used as we begin this unit next week Take your time and try your best! You will record your answers on a bubble sheet Please write PRE TEST on bubble sheet

9. Let’s think about this…. Question – How is sound created? Question – Why are sounds different? Question – How do we hear sounds?

10. 6.P.1.3 Vibrations, Sound and Hearing In this unit our objective is to: Explain the relationship among the rate of vibration, the medium through which vibrations travel, sound and hearing Where is this objective in our room? Let’s read our unpacked standard now “Popcorn Style”

11. Our Vocabulary Activity… You will now have 3 minutes to write down all the words from our unpacked standard that you do not know or understand GO! Now take your list around and share with at least 5 of your classmates! GO!

12. Unit Vocabulary Sound Energy Amplitude Frequency Decibel Pitch Volume Parts of the Ear (Outer ear, Ear canal, Middle ear, Eardrum Hammer, Anvil, Stirrup, Cochlea, Auditory nerve) Larynx (Voice box), Trachea, windpipe

13. Vocabulary – Sound Energy caused by vibrations (movement up or down or back and forth)

14. Vocabulary - Amplitude The loudness or softness of a sound ( the intensity of sound) Large amplitude creates a loud sound Small amplitude creates a soft sound

15. Comparing Amplitude and Sound Which wave is louder, why?

16. Who has been to a concert? What does an amplifier do to the music at a concert? When it is combined with a loudspeaker it can amplify electric guitars and other musical instruments. Makes the concert more intense!

17. Vocabulary - Frequency The number of sound waves that pass a point in 1 second

18. Frequency Humans hear frequencies ranging 20 – 20,000 hertz Dogs hear frequencies up to 45,000 hertz (That is why we cannot hear a dog whistle)

19. Table of Sound Frequencies

20. Vocabulary - Decibels The measurement of sound Sounds over 120 decibels = dangerous Long exposure to loud sounds will cause permanent hearing damage that cannot be repaired

22. Common Sounds in Decibels Link http://www.dangerousdecibels.org/education /information-center/decibel-exposure-time- guidelines/ http://www.dangerousdecibels.org/education /information-center/decibel-exposure-time- guidelines/

23. Vocabulary - Pitch The highness or lowness of a sound Determined by how fast something vibrates

24. Pitch and Sound – If an object vibrates quickly = it will produce a high-pitched sound ( has high-frequencies and short wavelengths) Flutes have a high pitch (due to high frequency)

25. Pitch and Sound – If an object vibrates slowly = it will produce a low-pitched sound ( has low frequencies and long wavelengths) Tubas have a low pitch (due to low frequency)

26. Vocabulary – Sound Waves Sound travels in Longitudinal waves (also known as compressional waves)

27. Do we remember this? Sound can only move through a medium Sound cannot travel in outer space (vacuum) Solid liquid gas fastest in solids slowest in gases

28. Examples: Sound in different mediums MediumSpeed Air 740 miles per hour Water 3,324 miles per hour Steel 7,435 miles per hour

29. Study Jams…Sound In a moment you will watch a video on sound. Before, write these questions in your notebook leaving 2 lines between each question 1. What causes sound? 2. How does sound travel? 3. What is the frequency of sound? 4. What is a sound’s pitch? 5. What is a sound’s volume and how is it measured?

30. Study Jams…Sound Remember you are listening to the video to find out the answers to your questions… http://studyjams.scholastic.com/studyjams/ja ms/science/energy-light-sound/sound.htm http://studyjams.scholastic.com/studyjams/ja ms/science/energy-light-sound/sound.htm

31. Sound Lab – Canosa to pick up here You will count off from 1 – 4 to form lab groups You will be investigating sound today using tuning forks You will record all information into your interactive notebook We will review the lab procedure together now
