To conduct a valid experiment, variables need to be identified and controlled. Summary. Students will help design an experiment to see if adding energy (heating) affects the rate of evaporation.
In this activity, students will be able to identify and control variables to design an experiment to see whether the temperature of a solvent affects the speed at which a solute dissolves. Students ...
