Sound Travel
Sound energy travels through water, air, and solid materials as a _________ from a source to a listener.
What is a wave?
What is a collision?
A ___ is something scientists create to help them answer questions and visualize things that are hard to see, like how sound travels at the particle level.
What is a model?
A ____ is a pattern of motion that travels away from a source.
What is a wave?
To ___ means to move back and forth quickly, which is what a sound source does to create waves.
What is vibrate?
The dolphin mother is considered the ___ because she makes the sound that travels to her calf.
What is the source?
When particles collide with each other in a sound wave, they ____ their energy to the next particles.
What is transfer?
Sound energy is a form of ___ that moves from place to place through different materials.
What is energy?
The ____ of a wave refers to the height of the wave.
What is amplitude?
In a sound wave traveling through water, the water particles move ___ and ___ (or back and forth), not in the direction the wave travels.
What is up and down?
When sound travels through a material, the particles in that material move only a _____, even through the sound energy travels far.
What is a little bit (or small amount)?
In a sound wave, particles collide and spread apart, then the next particles collide and spread apart. This pattern of _____ creates the sound wave.
What are collisions ( or particle collisions)?
The curved line that shows the pattern of a sound wave is called a ____
What is a waveform?
The distance from one peak of a wave to the next peak is called the ____?
What is wavelength?
Materials are made of ____ that are too small to see and are somewhat free to move when sound waves pass through them.
What are particles?
Sound can travel through different kinds of materials because all materials are made of ____ that are free to move and collide.
What are particles?
When a mother dolphin vibrates to make a sound, it causes the nearest water particles to move, which then collide with the next particles. This process ____ energy through the material.
What is transfers (or moves)?
Everything around us, including water, air, and rock is made of ___ that are too small to see.
When comparing two sound waves, if one wave has a larger amplitude than the other, the sound with the larger amplitude will be ____?
What is louder?
When a sound source vibrates, it first collides with the nearest particles. Those particles then collide with the ___ particles, transferring energy along the way.
What are next (neighboring)?
Explain how sound energy gets from a mother dolphin to her calf across a distance in the water.
What is sound energy travels as a wave through the water from the source (mother) to the listener (calf), and the water particles only move a little bit even though the sound travels far?
Describe what happens to energy and motion when two objects collide based on what you learned about sound waves in materials.
What is when objects collide, energy is transferred from one object to another, changing their motion, and some energy is also transferred to the surrounding air, creating sound and heat?
Explain why scientists use models like diagrams and Simulations to represent sound waves traveling through water.
What is because sound waves and particle collisions are too small for us to see directly, so models help us visualize and understand how sound travels through materials.
Explain the relationship between a wave's amplitude and the volume of sound that a listener hears.
What is when sound waves have different amplitudes, the listener hears sounds with different volumes: larger amplitude means louder sound, and smaller amplitude means quieter sound.
Describe the complete process of how a sound wave moves through a material at the particle level, starting from when the source vibrates.
What is when the source vibrates, it collides with the nearest particles and transfers energy, causing them to move; those particles then collide with the next particles and transfer their energy, which causes those particles to move; this pattern of collisions and energy transfer continues, creating a sound wave that travels through the material to the listener?
