Whats that Sound?

By Anonymous -

When something Vibrates or shakes very ,very quickly it makes the air around it vibrate too.When these vibrations travel to our ears we hear a Sound. 


 
 We made a long distant call!Using plastic cups threaded with string we held the cups so that the string was tight.One person  whispered into one cup while their partner listened with the other.The sound of one voice made the string vibrate carrying the sound to the other persons ear.







 Wow !!-the vibrations made by banging the tray made the air vibrate and the sound was carried to the bowl making the gladwrap vibrate and the rice on the top jump.












We have enjoyed mixing colours for our colour wheels.

Last term Room 3 had Performing Arts lessons each week. They learnt lots of different dances. On Friday, they shared one of the dances that they had learnt at the Full School Assembly. The audience sang as they did the dance. We hope you enjoy it!

  Diwali. We have been working hard during our Inquiry time learning about festivals and celebrations.The Indian festival of Diwali is centred around Light so we have been busy using our collage skills to create beautiful candles. Collage requires Patience and Perseverance. Well worth all the hard work though!! .     We also painted our own beautiful D iva's-  small candles which are placed around peoples homes during Diwali.   Lights welcome the New Year and create a happy festive atmosphere. Come into Room 3 and see what you think!

We are enjoying working with Mrs Hooke doing Performing Arts on a Thursday morning-moving to music and learning to make interesting shapes with our bodies. We also enjoyed having some time on Friday to construct models using old boxes,egg cartons etc.When describing our models we tried to think of interesting words. We spoke clearly and listened to each other.Some of the models were constructed in teams and we all co-operated together.    It's so enjoyable to work together. Well done Room 3!
