In this lab experience, students carry out an investigation to observe the color of copper(II) sulfate at different concentrations. They then repeat the investigation using glucose. Students learn that there is a relationship between the amount of solute dissolved in a solution and its properties. They also observe that there are limits to how much material can be dissolved.
Safety:
Before conducting the lab, review the safety precautions on the student page with the class. Then discuss any safety precautions that are specific to your science laboratory or classroom. Good ventilation is required since burning food can generate a large amount of smoke. Allow some time between trials so that the smoke has time to dissipate.
