Seeing Sound Practice

Xavi hits a drum with a drumstick and makes it vibrate. He rests his hand on the drum and stops the vibration. What happened to the sound of the drum?

• The sound stops because it cannot pass through his hand.

• The sound decreases in pitch because the vibrations have stopped.

• The sound becomes clearer because the vibrations have stopped.

• The sound stops because the vibrations have stopped.

The students in Ms. Morris' class use different methods to conduct investigations. Which of the following is an example of an experiment?

• making a scale model of the planets of the solar system

• determining the effect of sunlight on the growth of roses

• recording the number of species of birds in an ecosystem

• taking notes on where birds prefer to build nests

What is a change in pitch most related to?

• how loud the vibration is

• how soft the vibration is

• how long the vibration continues

• how fast the vibration moves back and forth

Which evidence is not the result of an observation?

• The rose quartz is the most beautiful rock in the collection.

• The arrowhead fossils all have the same shape.

• The volcano's lava flow advanced at 5 feet per second.
