Then choose two objects to use for building your soundmaker. Place the objects in the plastic bag I give you. Then write your name on the bag.
How Will You Build Your Soundmaker? Describe your ideas for building your own soundmaker. Which materials did you choose? How can you use these materials to build your soundmaker? How will you make a sound with your soundmaker? What will vibrate in your soundmaker? How will the sound get to your ears?
