Question

Wanda and Marita are drinking bottles of water. Each girl sounds a different musical note by blowing across the top of her bottle. What is a good hypothesis that could lead to new experimentation?

Answer 1

Different circumferences of bottle openings cause different pitches when air is blown over.

Answer 2

The probable hypothesis would be - If a bottle having less water in it, then the note played is lower due to the presence of the more air to move around.

Explanation:

The hypothesis is an idea that is able to explain some problems with prior knowledge or experiments but it is not able to prove it. The hypothesis is not just a guess or it is also not a well-sustained explanation it is in between.

In this experiment, a hypothesis can be formed on the base of the water quantity present in the bottle as we already know the more air present in some instrument or in a medium the lower the sound it will produce.

Thus, the correct answer would be - If a bottle having less water in it, then the note played is lower due to the presence of the more air to move around.
