5th Grade Topic 2 Quick Check Review

During math class, students were using a geoboard and a number of identical rubber bands to create geometric shapes. The rubber bands were stretched to different lengths. The students noticed that when plucked, the bands produced different sounds. Which statement explains this difference in sounds?

• The bands stretched tighter, vibrated faster, and created a higher pitch.

• The bands stretched tighter, vibrated slower, and created a higher pitch.

• The harder someone plucks a rubber band, the vibrations are slower, and the pitch is higher.

• The harder someone plucks a rubber band, the vibrations are very fast, and no sound is made.

When an object vibrates, causing air particles to move and vibrate, sound is produced. If the vibrations are fast, what feature of sound is heard?

• low pitch

• high pitch

• loud sound

• soft sound

A vase with flowers is sitting on the teacher's desk. What type of energy does this vase have?

• stored thermal energy

• released thermal energy

• stored mechanical energy

• released mechanical energy
