Our method is… We filled cups with different amounts of water and we whacked them and they each made different notes. We made a cup whacking xylophone with different materials of spoons and I made a song. Method
Hypothesis We think that that the less water the higher the note will be.
Results We found out that we were right because the more water the lower the note will be and the opposite way.
Conclusion We found out that our hypothesis was right because the sound waves had more water to travel in so it made a lower note. We had a lot of fun doing this experiment. So we hope you enjoyed our slide show.
