 Question 32: Open-Response Reporting Category: Waves and RadiationStandard: 4.3 - Distinguish between the two types of mechanical waves, transverse and longitudinal. A large anchor is being lifted into a boat with metal sides. As the anchor leaves the water it hits the side of the boat, making loud sounds and making waves on the surface of the water.Describe the motions of the sound waves and the water waves.Draw a diagram for each of the waves you described in part (a). Be sure to label each diagram.Describe how the wavelength is measured for the water waves.

Scoring Guide and Sample Student WorkSelect a score point in the table below to view the sample student response.

ScoreDescription
4 The response demonstrates a thorough understanding of the differences between transverse and longitudinal waves. The response correctly describes the motions of the sound waves and water waves, correctly diagrams each type of wave and labels them, and correctly describes how the wavelength is measured for the water waves.
4
3 The response demonstrates a general understanding of the differences between transverse and longitudinal waves.
2 The response demonstrates a limited understanding of the differences between transverse and longitudinal waves.
1 The response demonstrates a minimal understanding of the differences between transverse and longitudinal waves.
0
Response is incorrect or contains some correct work that is irrelevant to the skill or concept being measured.
