Sound Pitch and Water Volume Experiment

The video tutorial demonstrates an experiment called 'Bikar Menyanyi' to investigate how different volumes of water in a beaker affect the pitch of sound produced when struck. The teacher outlines the problem statement, materials needed, and the procedure for the experiment. Observations are made on how the sound changes with varying water volumes. The video concludes with a discussion on identifying manipulated, responding, and controlled variables.

What is the main focus of the experiment discussed in the video?

• Observing the evaporation rate of water

• Measuring the temperature of water

• Studying the color change of water

• Investigating the effect of water volume on sound pitch

Which of the following is the problem statement of the experiment?
