A good hypothesis is based on observations and must be testable.
a) Maybe music will effect the growth of plants.
b) If you give your dog three meals a day then it will be happier.
c) I think placing crickets in a box will make them chirp more sometimes.
d) If animals have more sharp teeth then dull teeth then they will eat meat.
e) Is oil denser than water? f) If you touch the Van de Graff generator
then you will be in a good mood.
