Waves, Energy and Information - Benchmark Amplify

Front

Movement of energy at a piano concert when it 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

A scientist studies the sounds of three different monkeys. She creates diagrams that represent the sounds each monkey makes. Study the diagrams and answer the question below. 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.

Front

Ali notices waves at the beach rise and fall, with some taller than others. Which idea about sound waves best represents this pattern?

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.

Front

Which plan would help an engineer design a cell phone to make pictures look brighter?

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.
