Question

Hypothesis: If the temperature of the liquid is increased, then more sugar will dissolve, because warm solutions hold more solute than cold solutions.

To test the hypothesis above, you changed the
of the solvent and
measured the
of a solid.
A 100 milliliter beaker contains about 50 milliliters of water, some ice, and a blob of material just poured into the beaker from a spoon.

Answer 1

To test the hypothesis you changed the temperature of the solvent and measured the amount (mass) of the solid that dissolved — i.e., the solubility of the sugar.

(Independent variable: temperature of the solvent. Dependent variable: amount/solubility of the solid dissolved.)
