This week's topic is all about sound. We have already done a little bit in school but don't worry if you have forgotten, there are some reminders below.
This week's learning
I can listen to and describe sound through a variety of mediums.
I can recognise that vibrations from sounds travel through a medium to the ear.
In school, we talked about sound occurs when an object sends vibrations through a medium to our ears. The medium could be air, water or even a solid object like a wall. Have you ever listened to sounds under water? Put your ear to a wall and try to listen to sounds coming from the other side. What do you notice? Why do you think the sound changes?
Try at least two of the following activities this week.
Make a youghurt pot telephone. Most adults will have made one when they were a child and they will need to help you make holes in the youghurt pots. Thay are great fun to make but can you explain how they work?
Go on a sound safari in your home, garden or local area but make sure your adults know where you are. Listen for sounds and write them down on the sheet. Can you tell if they are natural or manmade sounds? Some sounds are low and some are high, why is this?
How can we see sound? Watch the youtube clip and then invent your own experiment to see sound or just try to recreate the experiment in the video.
Finally, can you make a musical instrument from recycled materials? Can you change the pitch of your instrument?
You might want to make a percussion, string or wind instrument. What do you think these three words mean? Can you think of some examples of percussion, string and wind instruments? Try not to make it too loud as you might make your grown ups a bit grumpy.
