FRIDAY MORNING'S LESSON
We'll be looking at pitch this week and how instruments have a higher or lower sound.
On this page, there are 2 videos that will help to explain the information I will go through on the Powerpoint.
Your first task will be to complete the sentences in the 'Qualities of Sound' document (the words are on the bottom of the page to help you).
Your main task is to show in some way how either a STRING, WIND or PERCUSSION instrument changes its pitch. This could be as a poster or Powerpoint or step-by-step instructions or even as a drama performance! If you have an instrument at home, you could always make a video that shows the change in pitch - just remember to explain how it does it too. Use the books on GetEpic to help you as well - I've send you a list of Sound books that might be useful. Think about using the following vocabulary to make your explanation more scientific: pitch, vibrations, amplitude, higher, lower, faster, slower, wind, percussion, string, wave, plucking, blowing, striking.
The last two links (Water Xylophone experiment & Pan Pipe making) are instructions for making instruments where you can easily change the pitch with things you might have around the house. Give them a try and send me a video on ClassDojo of any song you make using your homemade instruments - be careful with the glasses in the first one!
CHALLENGE QUESTION: Which animals can hear the highest pitch and the lowest pitch?
(You might need to use the term 'frequency' to help you with this question.)
