Science - Experiment 6
The prac was completed successfully, was able to work with my peers/partner really well.
Completing this prac was successful, the sound produced numerous virbrations and you were able to hear it through the wood.
We know that:
When a sound is spoken through the microphone the waves go up and down, when a soft sound comes through the microphone the waves go really small and a loud pitch creates a larger waves.
The higher in pitch makes really tall and lots of waves whereas the lower pitch makes one long line.
This experiment provided up the class a good example of how sound is used and recorded.
Today I worked through the project ruler rumble. I was easily able to understand the project and managed it to get it done. The conclusions and what happened are below in the attachments.
Experiment 1 & 2
During class yesterday I was able to discover how sound vibrates through different metals and materials. I observed that when the tuning fork hit the rubber stopper, the tuning fork created a vibration which created the water to move/splash. Also when the tuning fork was still vibrating and the aluminium was placed against the fork, it bounced off and because of gravity the aluminium fell back against the fork repeating the process. The other practical report involved a aluminium can with a rubber stretched across the top and on top a solar power panel piece and when speaking into the aluminium can the sound waves went across to the outstretched piece of rubber shaking the solar panel which created the light to flicker and move across the wall. I learnt that voice of humans creates a sound wave to vibrate across the can.
