This is a lab you can do with middle grades students to demonstrate how surface area affects the rate/speed of a reaction. It describes a lab where groups of students use room temp water to see which dissolves faster - granulated sugar or a sugar cube.
Contains a lab sheet, data sheet with a place for hypothesis/prediction, and 5 reflection questions.

**Please note that dissolving is actually a PHYSICAL reaction, not a chemical one. The rate is still affected by the same factors - but this is a common misconception among students that we do not want to perpetuate. Make sure to mention it!**
