Making Sounds 3

In this worksheet, students will answer questions about how sound waves are made by vibrations and how they can be investigated by observation.

'Making Sounds 3' worksheet

Key stage:  KS 2

Curriculum topic:   Sound

Curriculum subtopic:   Sounds and Vibrations

Difficulty level:  

Worksheet Overview

QUESTION 1 of 10

Sounds are produced when a material VIBRATES. The vibrations travel in WAVES from the source through gases, solids and liquids by making them vibrate too.

 

We cannot always see the vibrations because they are too small, but there are ways that we can show the movement. For example, sand on a drum skin bounces when the drum is struck. We can feel the vibrations produced by our voices by feeling our throats as we speak or sing.

Let's explore all about making sounds...

Megaphone

 

Sounds travel from their source by making what vibrate?

heat

light

particles in materials

energy

Sounds cannot travel through which one of these?

brick

wood

glass

space

water

Astronaut

 

In space astronauts communicate by...

shouting really loud

morse code

radio

Match up the vibrating material with the musical instrument.

Column A

Column B

drum
skin
clarinet
string
guitar
reed
trumpet
air

We hear the music from instruments because the sound waves... 

travel through the air

travel through the radio

are loud

We cannot always see sound vibrations because they are...

invisible

too small

only in our imaginations

 Tilly and Mathew want to show their 'sound' learning to the rest of the class.

 

Drum kit

 

They sprinkle dry sand on the drum skin then hit the skin with a drum stick.

 

What will the students see?

no effect

the sand will 'bounce'

a sandcastle

Tuning fork

 

Matthew takes a tuning fork. He has a shallow bath of water. He makes the tuning fork vibrate and then touches the surface of the water.

 

What will the students see?

the water will ripple

the water will evaporate

no movement

Tilly lights tea light in a saucer of sand to make it safe.

 

Tea light Plastic cup

 

She points the open end of a plastic cup towards the tea light and flicks the bottom to make a sound.

 

What TWO effects could the students see?

the flame will flicker

the flame will go out

the flame will get bigger

When we use our senses to record our science learning it is called...

modelling

measuring

observation

  • Question 1

Megaphone

 

Sounds travel from their source by making what vibrate?

CORRECT ANSWER
particles in materials
EDDIE SAYS
Sound is a form of energy, but particles within a material have to vibrate for the sound to be made AND for it to travel.
  • Question 2

Sounds cannot travel through which one of these?

CORRECT ANSWER
space
EDDIE SAYS
Space is empty - there is nothing there to vibrate!
  • Question 3

Astronaut

 

In space astronauts communicate by...

CORRECT ANSWER
radio
EDDIE SAYS
Radio waves can travel through space!
  • Question 4

Match up the vibrating material with the musical instrument.

CORRECT ANSWER

Column A

Column B

drum
skin
clarinet
reed
guitar
string
trumpet
air
EDDIE SAYS
A trumpet is a long column of air which vibrates when the player blows into it. Drum skins and guitar strings are made from different materials which vibrate. A clarinet is a 'reed' instrument, the player makes the reed vibrate by blowing over it.
  • Question 5

We hear the music from instruments because the sound waves... 

CORRECT ANSWER
travel through the air
EDDIE SAYS
The vibrations made by the instrument make the air in the room vibrate. These sound waves travel to our ears through the air.
  • Question 6

We cannot always see sound vibrations because they are...

CORRECT ANSWER
too small
EDDIE SAYS
Sound vibrations can be very tiny - too small for us to see them, but still hear them!
  • Question 7

 Tilly and Mathew want to show their 'sound' learning to the rest of the class.

 

Drum kit

 

They sprinkle dry sand on the drum skin then hit the skin with a drum stick.

 

What will the students see?

CORRECT ANSWER
the sand will 'bounce'
EDDIE SAYS
As the skin vibrates, the energy will also make the sand bounce.
  • Question 8

Tuning fork

 

Matthew takes a tuning fork. He has a shallow bath of water. He makes the tuning fork vibrate and then touches the surface of the water.

 

What will the students see?

CORRECT ANSWER
the water will ripple
EDDIE SAYS
The vibrating tuning fork will make the water ripple as the sound travels from its source. It's like actually 'seeing' the sound vibrations!
  • Question 9

Tilly lights tea light in a saucer of sand to make it safe.

 

Tea light Plastic cup

 

She points the open end of a plastic cup towards the tea light and flicks the bottom to make a sound.

 

What TWO effects could the students see?

CORRECT ANSWER
the flame will flicker
the flame will go out
EDDIE SAYS
The sound waves make the air move (they 'push' the air) and this in turn will make the flame flicker or even go out. It's worth a try if you've got something like a plastic cup.
  • Question 10

When we use our senses to record our science learning it is called...

CORRECT ANSWER
observation
EDDIE SAYS
Whether you are seeing, hearing or feeling, you are observing - that's taking in information. That's the first stage in an investigation. Then you have to start interpreting that information.
