Mechanical Wave Propagation (MWP) |
Pace: 5.5 class periods

ESSENTIAL QUESTIONS
|
STANDARDS COVERED
P4.5A Identify everyday examples of energy transfer by waves and their sources. P4.5B Explain why an object (e.g., fishing bobber) does not move forward as a wave passes under it. P4.5C Provide evidence to support the claim that sound is energy transferred by a wave, not energy transferred by particles. 4.5D Explain how waves propagate from vibrating sources and why the intensity decreases with the square of the distance from a point source. P4.5E Explain why everyone in a classroom can hear one person speaking, but why an amplification system is often used in the rear of a large concert auditorium. |

PreTest and Differentiation
Pre-test data will be collected and used by the teacher to offer alternative projects to demonstrate mastery. You may also self select for an alternative assignment upon conferencing with your teacher. Please talk to your teacher if you have any questions. |
Chapter Textbook and Notes
All resources will be linked to the practice |
MWP.1 Energy Transfers
25-26 February
MWP.1 PracticeNOTES
Complete Cornell Notes using the Energy Transfer Module. There will be four slides. Potential / Chemical Energy Energy Transfer - Kinetic Energy Transfer - Light Not Enough Energy PRACTICE Review Water Waves and/or Wave Intro Video and explain why a fishing bobber does not move forward when a wave passes beneath it in your lab notebook. Complete the Wave and Energy Transfer Practice page below #1-6 and 10 only. Check with the key 
MASTERY CHECK
Draw a diagram in your notebook that shows a mechanical wave, the medium it is moving through and how that medium is moving. |
STANDARDS:
4.5A 4.5B 4.5C BIG IDEA: Mechanical waves are vibrations in a medium that move from source to receiver, conveying energy. | ||
MWP.2 Sound Waves
27 February
MWP.2 Practice
|
Please use headphones.
NOTES Create Cornell Notes or other using the Terms to Know while you watch the Bozeman Science Sound Waves video. Include drawings frequently to help explain terms. Most terms are explained but you might have to use prior knowledge from Chapter 25 for a few. Turn down the volume before you try part 2. Explain what is happening in this video of a Sound Wave Experiment based on your understanding of Sound Waves. Include your discussion at the bottom of your notes. PRACTICE Complete the Sound Waves Practice Page in class and check with the key for corrections. Check in with teacher when complete.
MASTERY CHECK
Complete #1-6 CHECK YOUR UNDERSTANDING questions at the bottom of the Physics classroom webpage in your notebook. Be sure to check your answers AFTER you have worked to complete the practice. |
STANDARDS:
4.5C 4.5D Big Idea: Sound is energy transferred by a wave, not energy transferred by matter. Terms to Know:
Mechanical Waves Longitudinal Waves Transverse Waves Frequency = Pitch Simple Harmonic Motion Amplitude = Loudness Harmonic Hertz (Hz) | ||
MWP.3 Intensity
2-5 March (3 March ACT testing and 4 March 1/2 day)
MWP.3 PracticeNOTES
Create Cornell Notes or other using the Terms to Know while you watch thenewboston Wave Intensity video. Include drawings frequently to help explain terms. Most terms are explained but you might have to use prior knowledge from Chapter 25 for a few. PRACTICE PAGE Complete the Sound Intensity Practice Page below in class or at home and check with the key for corrections. Check in with teacher when complete.
MASTERY CHECK
IN your notebook, explain why everyone in a classroom can hear one person speaking, but why an amplification system is often used in the rear of a large concert auditorium. Use a diagram that include wave diagrams and wave intensity to help explain. |
STANDARDS:
4.5D 4.5E Terms to know: Frequency Period Wave Amplitude Intensity Decibels (dB) Source Big Idea:
Wave intensity decreases with the distance from the source. Sound moves in all directions. | ||
