Waves, Energy and Information

A mother dog is communicating with her puppies by making growling noises. Once the growling noise leaves the mother dog, what happens next?

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

• As the sound moves through the air, particles in the air move back toward the mother dog.

• As sound moves through the air, particles in the air move a lot at first.

• As sound moves through the air, particles in the air line up and move toward the puppies.

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.

• Yes; the amplitude from Monkey 1 is the largest, which means the sound is the loudest.

• Yes; the amplitude from Monkey 1 is the smallest, which means the sound is the loudest.

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

• 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?

• 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.

Why should the engineer test her model?

• to make sure that the model is better than all other models

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

• to define the problem the engineer needs to address

• to determine the goals of the project

The fishing manager looks for information on the boats. Most of the fishing teams use the same kind of boat called the Pontus. The fishing business manager looks at the boat’s guide book and sees the following information.

What should the fishing business manager do based on today’s report?

• Allow all Pontus boats to leave the harbor.

• Prevent all Pontus boats from leaving the harbor.

• Find a different boat that navigates smaller waves.

• Wait until the waves reach an amplitude of 4 feet to leave the harbor.
