Question
A student is bouncing a ball off the wall in gym class to model for a fellow student how sound waves interact with surfaces. At first, the student bounces the ball off a concrete wall in the gym, shown in Models 1 and 2. In Model 1, the student throws the ball directly at the concrete wall, and the ball bounces back to him. In Model 2, the student throws the ball at an angle, and the ball bounces at an angle to the floor.
Model 1 and Model 2 show how a surface can change the (Select)
(Select)
speed

moving energy. This represents how sound waves are (Select) reflected off
absorbed by
hard surfaces. Model 3 and Model 4 show how moving energy can be (Select)
(Select)
reflected off
transferred to
other objects. This represents how sound waves are (Select)
(Select)
reflected off
absorbed by
soft surfaces.

Based on the context provided about how a student is using a ball to model sound wave interactions with surfaces, here are the appropriate selections to fill in the blanks:
Model 1 and Model 2 show how a surface can change the **direction** of moving energy. This represents how sound waves are **reflected off** hard surfaces. Model 3 and Model 4 show how moving energy can be **transferred to** other objects. This represents how sound waves are **absorbed by** soft surfaces.
