Science - Vibrations:

We can explore how vibrations create sound by sprinkling a little dry rice on the skin of a drum. When we strike the drum, the skin vibrates quickly, and these vibrations make the rice grains move and jump. This helps us see the vibrations that are normally invisible. The sound we hear is produced because the vibrating drum pushes against the air particles around it, creating sound waves that travel to our ears. The stronger and faster the vibrations, the louder and higher the sound becomes. This simple activity shows that sound is caused by vibrations moving through a medium like air.

Investigation

We also spent time investigating other instruments and how they vibrate to create sound waves. 

 

Times Tables Rockstar Day:

We had a great time celebrating Times Table Rockstars Day! We enjoyed creating our own Rockstar and designing a guitar. We did lots of TTR practise and enjoyed competing against the other Year 4 Class! We all looked amazing and enjoyed dressing up!

Science – States of Matter

For our Science unit, we looked at changing of states. We looked at how the particles change when an item is going from solid to liquid. To help us understand this we did a Science experiment on melting chocolate. We saw the different stages of the melting process and thought about how the particles must be during the different stages. We then were lucky enough to have a spoon of the melted chocolate – yum!
