We had a great time yesterday investigating sound.  We used a straw to make a sound and we changed the pitch of it by making it longer and shorter.  We found out that the longer the straw, the lower the pitch and the shorter the straw, the higher the pitch is.  We also found out that the harder you blow the louder the sound is.  We also worked with a partner to investigate sounds that elastic bands make.  In the classroom, we also had a range of activities to explore such as making a loud sound near a drum with rice on it to see the vibrations, hitting a tuning fork and placing it in water to see the vibrations, we listened to the sounds that a metal coat hanger made and we also played different notes on a violin and a xylophone.  What a wonderful afternoon we had!
