Julia did an experiment using drums. She compared the vibrations she felt and the pitch she heard listening to two different drums. Her data is shown in the table below. Data From Drum Investigation Type of Drum Vibrations Felt Pitch Heard Bass Drum slower vibrations lower pitch Snare Drum faster vibrations higher pitch Which conclusion fits the data she gathered? Larger drums make higher-pitched sounds. Faster vibrations make higher-pitched sounds. The type of drum does not affect the pitch. Slower vibrations make higher-pitched sounds.

2 2. In the picture below, the impalas can be seen in the water. What happens to light at the surface of the water that creates the upside down image of the impalas? The light is refracted. The light is turned into sound. The light is absorbed. The light is reflected. 3. The airplane windows in the picture are transparent. Which of the following must be true about the windows? Light passes through the window easily. Most of the light bounces back off of the window. No light is able to pass through the window. Only a little bit of light can pass through the window.

3 4. Vibration speed is measured in hertz. The graph below shows the vibration speeds and pitches of six sounds. Pitch & Vibration Speed of Sounds Which of the following can be concluded from the graph? As the rate of vibration increases, pitch decreases. The pitch of a sound is not related to vibration. All sounds have the same vibration speed. The higher the vibration speed of a sound, the higher the pitch. 5. Jordan was using different materials to make musical instruments. He hit a plastic pipe and a metal pipe with a stick. The metal pipe had a much higher pitch. Which of the following could explain why the metal pipe had a higher pitch? The pipes are made from different materials. The pipes are different colors. The pipes were hit with the same stick. The pipes are exactly the same size.

4 6. In the picture of the harp below, the string on the left is vibrating faster than the string on the right. If Sue is listening to both strings vibrating at the same time, then she should be hearing a sound that has no pitch. a sound that is very cold. two different pitches. only one pitch. 7. Which of the following always causes a sound to change pitch? changing the strength of the vibration changing the material that is making the vibration changing the speed of the vibration none of these 8. Which of the following surfaces reflects the most light? aluminum foil yellow cloth concrete sidewalk tree trunk

5 9. Garrett has four strings that are the same thickness and are made of the same material. Garrett cuts the strings to different lengths and pulls them to the same tightness. When he plucks the strings with his finger, which string will have the highest pitch? It is impossible to say. They will all have the same pitch. The longest string will have the highest pitch. The shortest string will have the highest pitch. 10. During a thunderstorm, Mel saw lightning flash in the distance. A few seconds later, Mel heard thunder. Which of the following is a reasonable explanation for Mel's observations? Light travels faster than sound. Thunder is not made by lightning. Thunderstorms are dangerous. You cannot hear thunder unless you are outside.

6 11. W. Ear drum vibrates. X. Air around tuning fork vibrates. Y. Tuning fork vibrates. Z. Tuning fork is hit. Which of the following shows the steps above in the order that they must occur for someone to be able to hear the tuning fork? Z Y X W Z X Y W Y Z X W W X Y Z 12. X-rays are high energy waves that can pass through many objects in much the same way that light travels through glass. A shield of lead can stop x-rays from going through it. Sound is another form of energy that moves in waves. Which of the following will stop a sound wave? a solid wall a glass window a lead shield a vacuum

7 13. The pencil in the picture below is completely straight, but it appears not to be. Why does the pencil look like it is broken? The light traveling from the pencil is refracted as it moves from the water to the air. The water changes the shape of the pencil. The water reflects all of the light that comes into contact with it. The water absorbs all of the light that hits the pencil.
