Ms. Meyer is at a Taylor Swift concert with her sister. Which of the following best describes the movement of energy at the concert as soon as the concert begins?
a. Sound energy moves from Taylor Swift to Ms. Meyer's ears.
b. Sound energy moves from Ms. Meyer's ears to Taylor Swift.
c. Sound energy moves from Taylor Swift to Ms. Meyer's ears, and then straight from her ears to her sister's ears.
d. Sound energy moves from Taylor Swift to Ms. Meyer's brain.
a. Sound energy moves from Taylor Swift to Ms. Meyer's ears.
A mother duck is communicating with her ducklings by making quacking noises. Once the quacking noise leaves the mother duck, what happens next?
a. As the sound moves through the air, particles in the air collide with one another.
b. As the sound moves through the air, particles in the air move back toward the mother duck.
c. As sound moves through the air, particles in the air move a lot at first.
d. As sound moves through the air, particles in the air line up and move toward the ducklings.
a. As the sound moves through the air, particles in the air collide with one another.
What question would you ask to determine if energy has been transferred from one air particle to another?
a. Did the particles get bigger?
b. Did the particles come from a source?
c. Did the particles change direction?
d. Did the particles change their shape?
c. Did the particles change direction?
4. A scientist studies the sounds of three different dolphins.
She creates diagrams that represent the sounds each dolphin makes.
The scientist makes the claim that Dolphin 1 makes the loudest noises. How would the diagram look in order for her claim to be accurate?
The amplitude of the wave diagram would have to be the biggest.
Luke is at the beach with his family. He notices that the waves flow toward the shore and make a pattern of rising up and falling back down. Some waves are taller than others. Luke has been studying sound in school, and he thinks this reminds him of something he learned. Which of the following ideas (that he has learned) best represents the type of patterns he notices with the ocean?
a. All sound waves from animals have the same amplitude.
b. All sound waves from animals have the same wavelength.
c. Some sound waves from animals have higher amplitudes than others.
d. Most sound waves from animals do not have amplitudes or wavelengths.
c. Some sound waves from animals have higher amplitudes than others.
Why are patterns important for digital communication?
a. Patterns in the code help to keep the message secret.
b. Patterns help the digital device to send electrical signals.
c. Patterns create a code that the sending device and receiving device can understand.
d. People who receive the messages use the code pattern to create a new code.
c. Patterns create a code that the sending device and receiving device can understand.
Apple is designing a new type of cell phone with a special feature. The goal is for the phone to make pictures look brighter. Which of the following plans would help with this design process?
a. They should test one combination of binary code and then implement it in the new phone.
b. They should test different combinations of binary code in an older phone before testing in a new phone.
c. They should test different combinations of binary code to see which solves the problem in the new phone.
d. They should test the one combination of binary code she thinks will work.
c. They should test different combinations of binary code to see which solves the problem in the new phone.
An engineer, Mrs. Reams, is designing a model of ocean waves. she wants to use it to teach science students. Why should Mrs. Reams test her model?
a. to make sure that the model is better than all other models
b. to make sure that it meets the criteria and to identify any failure points
c. to define the problem the engineer needs to address
d. to determine the goals of the project
b. to make sure that it meets the criteria and to identify any failure points
Two birds (A and B) are in a tree. One bird (A) makes loud noises at the other one (B). Explain how sound energy is related to this example.
a. Sound energy is transferred from bird B to bird A.
b. Energy is created by bird A.
c. Energy is transferred from the ground, then to bird A, and then finally to bird B.
d. Energy is transferred from bird A to bird B.
d. Energy is transferred from bird A to bird B.
If the amplitude is increased, how does the sound change?
When given a slinky toy and a yellow rope, which material can be used to model a LONGITUDINAL WAVE (side to side)?
slinky toy
When given a slinky toy and a yellow rope, which material can be used to model a TRANSVERSE WAVE (up and down)?
yellow rope
What is the difference between a LONGITUDINAL WAVE and a TRANSVERSE WAVE?
a longitudinal wave moves side to side and a transverse wave moves up and down
When looking at a waveform diagram, and without listening to the sound itself, how can you determine the sound's volume?
a taller amplitude wave will be a louder sound and a shorter amplitude will be a quieter sound
When looking at a waveform diagram, and without listening to the sound itself, how can you determine the sound's pitch?
A stretched out and wide wavelength creates a lower pitched while a squeezed together and narrow wavelength creates a higher pitch.
