Liam and melinda have completed one trial testing the freezing point of several solutions, but they cannot agree on what to
do next in their experiment
what should be the next step in their investigation?
repetition, completing more trials for each solution
analysis, determining whether their data are precise and accurate
further investigation, testing new solutions and comparing them to their original data
replication, asking about their classmates findings to compare data
sube

answer:

explanation:

1. write hypothesis that predicts how each solubility factor will affect the solution. does it make it sweeter, watery, murky, or grainy? how does it compare to the control drink made according to the powdered drink mix package? the solubility factors to test are heating the solvent, stirring the solvent, and decreasing the particle size before dissolving the drink mix in the solvent.  

an example hypothesis could be: heating up a solvent increases the sweet taste of a powdered drink mix.

2. list your controlled variables, independent variable, and dependent variable for each test of the experiment.  

the answer would be d

a physical change is being made.
