• plastic drinking straws
• scissors

1. Ask an adult for permission to use scissors. Cut one end of a straw so it comes to a dull point.
2. Put the cut end of the straw in your mouth, so that your teeth gently press on the straw, near where you made the cut. Close your lips around the straw, and blow hard through the straw... it makes a sound!

Try making several oboes of different lengths... what do you notice?

the sound is higher
the sound is deeper
the sound is lower
