Study Notes
Module L: Waves and Their Applications
- This module focuses on waves and their applications.
- Unit 1: Waves is the first unit.
Day 1 - Objectives
- Draw a mechanical wave.
- Explain the relationship between frequency and wavelength in a wave.
- Investigate the energy of a wave on a spring.
Starter
- Identify the differences between two depicted waves (Wave 1 and Wave 2).
Group Work Activity
-
Students will discuss and answer questions related to the given activity sheet.
-
Students will share and calculate the speed of waves.
-
Each group will use a device to simulate a wave on a spring.
-
Students will share answers, and the teacher will provide feedback.
-
All questions must be answered and returned to the teacher.
-
Students will be provided with frequency, wavelength, and wave speed data for Jack, Tom, and Alex.
-
A question asks which student has less energy applied to the spring and why.
-
Another question asks about the relationship between wavelength and wave speed.
Exit Ticket
- Students will complete an exit ticket at a link provided.
Day 2 - Lesson 2: The Behavior of Mechanical Waves
-
Standards:
- MS-PS4-1: Use mathematical representations to describe a simple model for waves that includes how the amplitude of waves is related to the energy in a wave.
- MS-PS4-2: Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.
Objectives
- Define a sound wave.
- Identify the meaning of loudness.
- Describe pitch.
- Explain how particles of a medium behave when a wave passes them.
- Compare the speed of sound waves transferred through gas, liquid, and solid.
Vocabulary
- Sound wave
- Loudness
- Pitch
Starter
- Label parts of a diagram. The diagram shows a wave and particles. The parts to label include A, B, C, and D.
The Behavior of Mechanical Wave - Sound Wave
- Sound waves carry energy through the air.
- When you shout, your friend receives the energy as sound.
- The air does not move from your vocal cords to your friend's ear.
- Air particles vibrate as energy passes.
Defining Sound Waves
- Sound waves are longitudinal mechanical waves caused by the vibration of medium's particles as the wave travels through a medium.
- Mechanical waves require a medium.
- Sound waves are longitudinal.
- Water waves are transverse.
- Electromagnetic waves do not require a medium.
- Light is an example.
What is a sound wave?
- A longitudinal mechanical wave caused by the vibration of medium's particles.
Check Your Understanding
- Where does sound travel faster (solid, liquid, or air)? Explain.
Sound Wave, Its Media, and Speed
- Sound travels fastest in solids, then liquids, then air.
Why?
- The closeness of particles in solids allows sound to travel quicker.
Materials (Solid, Liquid, Gas)
- Solids have tightly packed particles, liquids have loosely packed particles, and gases have widely spaced particles.
Checking Understanding:
- Describe how sound waves transfer energy.
- A sound wave passes a particle, how does the particle move?.
- Particle vibrates vertically, moving up and down.
Day 3 - Loudness and Pitch
- Objectives:
- Identify the meaning of loudness and pitch.
- Explain the relationship between loudness and energy, frequency, and pitch.
- Classify sounds as loud/soft or high/low pitch.
- Compare and contrast loud/soft sounds and high/low pitched sound from a given wave.
Test the Sound
- Test the sound of various materials to identify sounds (loud, soft, shrill, or deep).
Properties of Sound
- Loudness is related to volume/amplitude, and relates to energy.
- Pitch is related to frequency, or how high or low the sound is.
Properties of Sound (Summary):
- Loudness is related to the volume of sound and directly to the amplitude. Higher amplitude = louder sound
- Pitch is how high or low a sound is, and is directly related to frequency. A high-pitched buzz means sound waves have a high frequency reaching your ear.
Video Assignment (Plenary)
- Watch a video about the properties of sound using the provided URL.
Day 4 - Reteach with Activities
- Review of vocabulary (sound wave, loudness, pitch).
Reinforcement/Starter
- Label waves (loud/soft, high/low pitch).
Copybook Activity
- Draw different types of sound waves (loud/high, loud/low, soft/high, soft/low).
Comparing and Contrasting
- Compare and contrast the drawn waves.
Check Your Understanding:
- Describe how sound waves transmit energy. Label the provided sound wave illustrations.
Group Activity - Pitch & Loudness
- Each student records their voice (loud/soft).
- Record high and low-pitched sounds.
- Draw observations in a copybook.
Group Activity - High or Low Sound
- Write answers about a video demonstrating high and low sounds. Watch video using the provided URL.
Extended Activity - Quizizz
- Complete a quiz at the provided link.
