Help w/ Evaporating Water!
Posted: Sat Dec 08, 2012 12:44 pm
Hello! My son is trying the "How Salty is the Sea" project, and we are now conducting the experiment. We chose 5 water samples, and we put them in the larger baby food jars. They are in the oven at 220 degrees as we speak. The experiment states that it takes a few hours to evaporate... 2.5 hrs have passed and the water levels haven't decreased at all! Am I missing something? Thanks!
