This is a mini-lab activity that is designed to be completed and reviewed in one class period, quick and easy. It could even be used as a station within this topic. The materials are very simple - thermometers, cups and food coloring. Students get the opportunity to practice measuring temperature as well as observing how water temperature affects the speed at which food colorings mix. Includes the following sections: materials, procedure, data table, and analysis (includng claims/evidence/reasoning section). Analysis focuses on how particle motion is affected by temperature. Directly supports both NGSS MS-PS1-4 and MA 8 MS-PS1-4.
