Science Experiment: Does Sound Travel Equally Well Through Different Materials? by Rosie
5MJ investigated in various materials to find out whether all materials travel equally well. We made a prediction and then created a fair test to investigate our original question. Do you know what 'factors' means in this experiment. See if you can work it out...
Prediction: No, for example sound travels through paper more easily than brick.
Method:Carefully wrapping, we will cover the logit in chosen materials. We will measure the decibels with a logit.
How will I make it a fair test? We will use the same amount of material and we will place the logit and buzzer the same differnce apart each time.
What factors will I change? We will change the materials
What factors will I measure? We will measure the decibels
What factors will I keep the same? We will keep the buzzer the same annd the logit the same.
|Material||Decibels measured (volume)|
Conclusion: I can conclude that sound does not travel equally well through all materials. From the results I can see that foil lets out the most decibells. The shape and the size are not the same E.G. control and leather.
