Energy

Throughout term 4 Te Pahu school has bee studying energy. so far we have learnt what energy is and the different forms it can take. One of the main forms of energy we have been learning about is sound and its characteristics.

With the amazing teaching of Mr Marquand we have learnt through YouTube videos, walking about 100 M awat and having Mr Marquand clap to blocks together and listening to the delay of the sound, spoons connected to our ears with wool and banging it on a solid obgect to hear the difference in sound, bull roarers (pieces of wood and string spun around to vibrate the air and make interesting noise), slinky pushed to show how sound travels, sugar on tin then patted to see vibrations and putting our ear up to the table and taping it showing how sound travels faster through solids.

some of the interesting points and surprises were sound travels through solids faster than liquids, a sonic boom happens when something goes faster than the speed of sound, the vibration of molecules travels sound like waves and thunder comes after lightning because the lightning is far a way and the sound of thunder is delayed.

at the end of this some of us still have questions like can heat change into a different form or how does sound bounce and go through things. the most of us understand everything but some are still clueless
