Grade 5 Science: Sound Quiz

1. What is sound?

Sound is anything that can be heard and is a form of energy.

Sound is a solid material that can be touched.

Sound is a type of light.

Sound is a form of temperature.

Sound is a form of energy that travels through matter as waves, allowing it to be heard by the human ear.

Explanation

Sound is a form of energy that travels through matter as waves, allowing it to be heard by the human ear.

2. Why do we use sound?

We use sound for entertainment purposes only.

Sound is used solely for creating music and songs.

Sound is used to scare away animals in the wild.

We use sound to communicate with others to find out about what’s going on around us.

Sound serves multiple purposes in our daily lives, including communication and situational awareness. While entertainment and music are common uses of sound, its primary function is for conveying information and understanding our surroundings.

3. What is energy?

Energy is the same as power.

Energy is only used in machines to generate electricity.

Energy is the force of gravity acting on an object.

Energy is the ability to make things move. It is needed to start the vibrations that make sound.

Energy is the capacity to do work or create change in a system. It can be in various forms such as kinetic, potential, thermal, chemical, etc., not limited to just making things move or producing sound.

4. How is sound created?

Sound is created by the speed of the air in a room.

Sound is created by the color of the object producing it.

Sound is created by the temperature of the environment.

Sound is made by the vibrations of an object. To make a sound, all or part of the object has to vibrate.

The correct answer explains that sound is produced through vibrations, not by the speed of air, color of the object, or temperature of the environment.

Explanation

The correct answer explains that sound is produced through vibrations, not by the speed of air, color of the object, or temperature of the environment.

5. What are vibrations?

Vibrations are side to side movements of an object.

Vibrations are the back and forth movements of an object. Vibrations can be powerful, weak, fast or slow.

Vibrations are stationary movements of an object.

Vibrations are circular movements of an object.

Vibrations involve back and forth movements, not stationary, circular, or side to side movements.

Explanation

Vibrations involve back and forth movements, not stationary, circular, or side to side movements.

6. What are sound waves?

Invisible rays emitted by the sun.

A type of electromagnetic radiation.

Sound waves are vibrations that make sound.

Particles that travel at the speed of light.

Sound waves are mechanical waves that require a medium to travel through, unlike electromagnetic radiation which can travel through a vacuum.

Explanation

Sound waves are mechanical waves that require a medium to travel through, unlike electromagnetic radiation which can travel through a vacuum.
