As we are looking at our senses and hearing, we would like you to try to make a 'shaker'. You could use an empty plastic bottle with a lid and put in some rice. Try different amounts of rice to see if it makes a different noise. Try using pasta or dried beans to see if the noise changes.
If you don't have a bottle, you could use a plastic cup with a piece of paper to cover the top and an elastic band to secure it.
