what would be a good hypothesis for this problem? "What affect will adding sugar have on the viscosity of water?"
t depends on the temperature of the water and what you are adding to it. if the water is warm enough to melt sugar then the velocity is lowed because sugar makes the water thicker and the water changer a slight hint of yellow. but if you add salt, it just changes the chemical compound but really has no effect because sugar is heavier than salt.
Hypothesis is an explanation for a set of observations, which is usually in experiments. For this, you might guess: Adding sugar will make water more viscous due to the high amount of concentration of sugar by breaking of hydrogen bonds and so forth... Something like that. It is an educated prediction of what you will guess to happen.
