A track runner is getting ready to run a sprint at a track meet after school. To begin, the track officiator blows a whistle. The runners all hear the sound and begin to race around the track. Which statement best describes the medium through which sound waves move to allow the runners to hear the whistle?

• The medium is the air.

• The medium is the whistle.

• The medium is the skin around the ears.

• Sound requires no medium.

A student makes observations about a wave in their science notebook. Another student notices the sticky note and makes an inference. Which inference is the 2nd student likely to make about the wave described in the note?

• The 1st student was describing a sound wave.

• The 1st student was describing a light wave.

• The 1st student was describing a gamma wave.

• The 1st student was describing a radio wave.

A student is conducting an experiment to test the perception of cell phone sounds and vibrations in a glass jar with all of the air . The student has the phone settings set to vibrate AND ring when a text message is sent to the phone. The student set up 3 different experiments, described in the table. The ability to hear the phone and the ability to feel the glass jar vibrate were measured. Which conclusion can be drawn from the interpretation of the data?

• Sound can be heard in all cases but vibrations only occur through the air.

• The phone was unable to receive text message signals when placed in a jar.

• Vibrations can occur through the glass jar but sound cannot be heard in a vacuum.

• The loose cap allows the metal from the lid to vibrate against the jar to transmit sounds from the cell phone.
