Mechanical Wave Propagation (MWP)
Pace: 5.5 class periods
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
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
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
Draw a diagram in your notebook that shows a mechanical wave, the medium it is moving through and how that medium is moving.
Mechanical waves are vibrations in a medium that move from source to receiver, conveying energy.
TERMS TO KNOW FROM Ch 25:
MWP.2 Sound Waves
Please use headphones.
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.
Complete the Sound Waves Practice Page in class and check with the key for corrections. Check in with teacher when complete.
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.
Sound is energy transferred by a wave, not energy transferred by matter.
Terms to Know:
Frequency = Pitch
Simple Harmonic Motion
Amplitude = Loudness
2-5 March (3 March ACT testing and 4 March 1/2 day)
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.
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.
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.
Terms to know:
Wave intensity decreases with the distance from the source.
Sound moves in all directions.
