Suzy - awesome job on your photos!
SCIENCE 2 - the boys missed David today, I hope he had fun with Grandpa and Grandma. We talked about vocal chords and how they work. Learned how we change the pitch and volume of our voice. Did experiments using balloons and yarn and watching the vibrations and how the end of the balloon is like the vocal chords - needs to be tightened to produce sound. I asked them to think about how people who have had their vocal chords removed are able to talk using a microphone against their throat. They are getting very good at applying what they already know to these kinds of questions. Key ideas for this unit - vibrations produce sound and everything is vibrating, pitch is either high or low, volume is loud or soft.
See everyone tomorrow, Rachelle
