:lightbulb: A hypothesis is an informed guess as a results of an experiment;including quantity [how much] and dimension.but on ordinary guess

like a exmple
write your hypothesis as an If/then statement.
If this done,
Then this should happen.
Example:IF I water the plants, then they grow.
or like this If insecticide is sparyed on lime bean plants, then the plants will be protected from insect.

Hypothesis
 
The hypothesis can probably be..."If I tighten the rubber bands then the sound will become higher. If i loosen them the tone will be deeper":)

Hope all goes well,
