Science – Planning an Investigation into Sound


Today, you are going to bring together all of your learning over the past few weeks to plan an investigation into sound using materials from home.


Remember, we MUST make sure that our investigations are FAIR! This means you only change one part of the investigation (one variable). All other parts (variables) must remain the same!

Open and read the Investigation PPT below.

Then follow this link to help you plan your investigation:

Science – All About the Ear!


Start by following these links and watching the clips:


How do ears work? -

How do animals hear? -

What can help us to hear? -


Now open and read the following PPT then try the activities that follow:

High and Low Pitch Clip -


Choose an object from your home that you can create sound with. Try to change the volume and the pitch of the sound you make.


Copy and complete the sentences below.


Name of Object: ___________________________________________________


To make this instrument louder I had to________________________________________________________________________________________________________________________________

To make the pitch high I had to _________________________________________ _________________________________________________________________

To make the pitch low I had to__________________________________________ _________________________________________________________________

Repeat with different objects.


Now try playing this game of Higher or Lower Pitch:


Amplitude – the larger the amplitude, the louder the sound

Wavelength – the shorter the wavelength, i.e. the higher the frequency (number of waves per second) of waves, the higher the pitch


Using the images of soundwaves you have seen on this page, try drawing some of your own for sounds you have made using different objects.

LI – to understand how sound travels

Watch the following clip -

Next, we will play a game:

  • You’ll need a few people in your house to play with you.
  • One person needs to be the ‘tapper’. Everyone else sit silently, head resting on a desk, eyes shut.
  • If you are tapped on the shoulder, you should knock gently on the table.
  • Everyone else should then, without looking, point in the direction of the source of the knocking sound.
  • Everyone hold their ‘points’ and open their eyes. Are they all pointing in the same direction?
  • Repeat a few more times. Are people always pointing in the same direction?
  • Repeat with a softer sound. Person tapped on the shoulder should gently tap the table with one finger. Did everyone get the correct general direction? How did we know where the sound was coming from? We heard it through our ears.
  • How did the sound travel from the source to our ears?


Next, watch these clips -


What can you see happening? The tuning fork is vibrating and the ripples move outwards from the sound source (the fork). This is how sound travels, by causing the particles around the vibrating source to vibrate, which in turn vibrate other particles, sending a ripple away from the vibrating sound source. We usually hear sound that has travelled through the medium of air, but it can also travel through solids and liquids.


Now, you are going to create your own string telephone. Watch the instructional video below:

Which of these sounds can you find in your home?


What is noise pollution? Discuss it with the people you live with, then watch the following clip:

Week Commencing 30/03/2020



Watch this episode of Frozen Planet:

Discuss what is happening to the ice.

How does this link into what we know about the water cycle?

Which parts of the water cycle can you observe during the episode?

Why is this happening?

What impact will it have on the wildlife in these icy regions of the world?
