Waves, Energy and Information - Benchmark Amplify

Front

Maria is at a piano concert with her sister. Which of the following best describes the movement of energy at the concert as soon as the concert begins?

Back

Sound energy moves from the piano to Maria’s ears.

Front

How close together are the waves?

Back

wavelength

Front

What happens to particles in the air when a mother dog's growling noise moves through the air?

Back

As the sound moves through the air, particles in the air collide with one another.

Front

What question would you ask to determine if energy has been transferred between interacting air particles?

Back

Did the particles change direction?

Front

The scientist makes the claim that Monkey 1 makes the loudest noises. Is her claim accurate? Explain using evidence.

Back

No; the amplitude from Monkey 1 is the smallest, which means the sound is the quietest.

Ali 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. Ali 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? Options: All sound waves from animals have the same amplitude, All sound waves from animals have the same wavelength, Some sound waves from animals have higher amplitudes than others, Most sound waves from animals do not have amplitudes or wavelengths.

Back

Some sound waves from animals have higher amplitudes than others.

Front

Why are patterns important for digital communication?

Back

Patterns create a code that the sending device and receiving device can understand.

An engineer 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? The engineer should test one combination of binary code and then implement it in the new phone., The engineer should test different combinations of binary code in an older phone before testing in a new phone., The engineer should test different combinations of binary code to see which solves the problem in the new phone., The engineer should test the one combination of binary code she thinks will work.

Back

The engineer should test different combinations of binary code to see which solves the problem in the new phone.

Front

Why should the engineer test her model of ocean waves?

Back

To make sure that it meets the criteria and to identify any failure points.

Front

Two squirrels (A and B) are in a tree. One squirrel (A) makes loud noises at the other one (B). Explain how energy is related to this example.

Back

Energy is transferred from squirrel A to squirrel B.
