Grade 8 Marine Science students are studying solubility and temperature, looking at water as the universal solvent. In this water chemistry lesson, students learned how different temperatures may affect solubility. This hands-on experiment allowed students to visualize what they have been learning so far and will tie into upcoming conversations about climate change.
Students observed as their test subjects (M&M candy) were submerged in different temperature water–cold, room-temp, and hot. Over the course of one minute, the coating on each of the 3 M&Ms began dissolving at different rates. Students were asked to think about these changes on the molecular level, and the differences in the way water molecules move in the varying water temperatures.
Having the ability to conduct a hands-on test and visualize solubility helped students make connections between their readings and lectures.
