Help! I need a little help with Science Homework.
Its all about solutions like these Keywords: Solution, Solute, soluble, solvent, Saturated, Dissolve, Insoluble.
If you have an answer can you use words like them above please, Thanks :)

I can't answer three, but heat is definately a factor.

As u know  solution is a homogeneous mixture composed of two substances  solute and  solvent. In such a mixture a solvent is a liquid, solid, or gas that dissolves another solid, liquid, or gaseous solute, resulting in a solution that is soluble in a certain volume of solvent at a specified temperature.
Solute,is the  substance dissolved in fluid, forming a solution.In here, Solute glucose is dissolved in solvent water to get a Glucose solution

solubility or how much of solutes dissolve  in a given volume of solvent depends on several factors and there is a maximum value for this at given conditions. this maximum also known as saturation is the point at which a solution of a substance can dissolve no more of that substance and additional amounts of it will appear as a precipitate

However, the point at which a solution can become saturated can change significantly with different environmental factors, such as temperature, pressure, and contamination. so u can change the solubility of Glucose by changing any of these factors.
but As i notice, u are asking abt  ways to increase  the   rate of dissolution of solute. In this case Glucose . increase in  solubility does not guarantee  increase in dissolution rate,
A)but increase in temperature would increase the dissolution rate,
B)other than this stirring also would also increase the solubility rate .
C)use of well grounded glucose also would  increase the rate

A)Increase temperature - Provides an increased amount of kinetic energy to the molecules allowing more of the molecules to have the necessary activation energy, Ea, to react. Therefore, the reaction speeds up.
Ex. An ice cube melts faster at 100°C than 50°C
In this case reaction is dissolution of Glucose in water

B,C)Increased surface area - Molecules can only react if they interact with one another (touch). By increasing the surface area, there will be more readily available molecules to react therefore, the reaction speeds up.
Ex. Powders dissolve faster than solids
      Stirring would increase the  interaction of molecules
