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? - https://www.youtube.com/watch?v=RiVx5Lih_44
How do animals hear? - https://www.youtube.com/watch?v=EowcFKQPYcI
What can help us to hear? - https://www.youtube.com/watch?v=mptjEoHF2aI
Now open and read the following PPT then try the activities that follow:
Have a look on the British Sign Language website (http://www.britishsignlanguage.com/) then watch the following clip and try the activity below:

LI – to understand pitch
'What is Sound' clip - https://www.youtube.com/watch?v=3-xKZKxXuu0
Complete sections 1 and 2 of this online activity:
Follow these links: http://www.bbc.co.uk/schools/scienceclips/ages/9_10/changing_sounds.shtml
High and Low Pitch Clip - https://www.youtube.com/watch?v=yMLTF_0PAQw
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: https://www.youtube.com/watch?v=0yuEM3IfLX0
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 - http://www.bbc.co.uk/education/clips/zkbygk7
Next, we will play a game:
Next, watch these clips - https://www.youtube.com/watch?v=XnTYb8k_ElY
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?
